This fish (different from the knife fish above) emits electric pulses at frequencies betwen 250 and 600 per second for electrolocation and communication. M. Kawasaki, at the University of Virginia, has investigated what happens when two of these fish operating on similar frequencies meet. Ordinarily, the fish would jam each other's sensory apparatus and "blind" each other. To circumvent this Eigenmannia has evolved a "jamming avoidance response," in which they both shift their pulse frequencies away from each other. To accomplish this, the fish must be able to detect time disparities between the two sets of signals less than 1 microsecond long. Their individual electroreceptors are not capable of handling such small time differences. Kawasaki has concluded that the jamming avoidance response can come only from highly sophisticated signal processing in the fish's central nervous system. (Kawasaki, Masashi; "Temporal Hyperacuity in the Gymnotiform Electric Fish Eigenmannia ," American Zoologist , 33:86, 1993.) Comment. Echo-locating bats and dolphins also possess sophisticated data processing apparatus for analyzing the echos they receive back from their prey and surroundings. It will be interesting to discover if evolution has come up with similar organic "components" for handling acoustic and electric signals. Further, we know ...

These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture. In another remarkable example of evolutionary convergence, these bioluminescent organs emit light spectrally matching the eye sensitivity of deepsea fish! So far, though, this story is not any more amazing that many others woven into evolution's fabric. But suppose that a deviant species of deepsea fish upset this cosy status quo by evolving visual pigment and bioluminescent organs operating in a part of the electromagnetic spectrum that other deepsea fish could not perceive. It would be as if this species had radar but the others did not! Well, three genera of dragon fish do ...

Some are true parasites. Attached by their teeth, they drink the blood of their hosts. Other fishes have fins that have been transformed into adhesive disks that allow them to also live inside the mouths and gill cavities of larger fish. These are true symbionts that feed on food scraps. The sizes and shapes of these invaders are neatly adapted to the mouths and cavities of each host. It is possible, but not easy, to explain how these remarkable physiological and behavioral transformations were initiated and perfected via random mutations and natural selection.

To understand the answer to the electric fish puzzle, we must restrict the discussion to those fish with active electric sensing systems. This group includes electric eels, South American knife fish, and African elephant snout fish. All of these have evolved, in a remarkable instance of parallel evolution, the capability of generating pulses of electricity. These pulses (up to 1,000 per second) radiate through the surrounding water. Prey and other nearby objects distort these oscillating electric fields. Electroreceptors on the fish and a sophisticated data processing system convert the field distortions into an "image" of the surroundings. M. and S.J . Lannoo, of Ball State University, have watched the black ghost knife fish, which plies murky Amazon waters, approach likely prey tail first. Swimming backward using an elongated belly fin, the knife fish slowly cruises past its potential victim. If the electrical image looks appetizing, the knife fish grabs its dinner with a forward lunge as it appears in front of it. "The researchers suggest that the fish swims past objects in order to scan them with its electroreceptors. This is the only way the fish can identify prey because an electric sense cannot be focussed like an eye. But if the fish carried out its scan by swimming forwards, the prey would end up ...

(From: Eastman, Joseph T,; Antarctic Fish Biology , San Diego, 1993.) In the frigid waters ringing the continent of Antarctica live approximately 275 species of fishes, 95 of which are assigned to the suborder Notothenioidei. This particular group of fishes is renowned for its unusual adaptations, as outlined below by D. Policansky: "Some of them have glycoprotein antifreezes in their blood, some have no hemoglobin, some have so small a temperature tolerance that they die at temperatures above 4 C, some are neutrally buoyant despite lacking swim bladders, and some live as deep as 2950 meters. The suborder has no known fossils, largely because no bony feature -- indeed, no single character of any sort -- can be used to define it. How did these animals arrive there, what are their ancestors, how do they make a living in such an environment, and how can they support commercial harvests?" (Policansky, David; "Southernmost Fauna," Science, 264:1002, 1994.) Comment.

I have noticed during passages around the world how the colours do apparently change, varying from almost trans-lucent purple to a deep navy colour, and wonder how many other colourings of flying-fish wings have been reported. "I think that flying fish are just taken for granted but perhaps if we looked at them more closely, then we may see some really weird and wondeful colours, especially in island areas. What does baffle me, is why, when the wings are only extended during flight, they should be of differing colours. I could understand it if they were a coral-swimming fish where the colours are designed to help them blend into the coral colours and so evade capture, but why the need in flight over crystal clear waters like the Coral Sea?"

It is also the home of more than 300 species of cichlid fishes. Ordinarily, that number of different species would pose no problem for the biologists -- look at the 400 or so species of hummingbirds in Central and South America! Lake Victoria, however, is a very young lake, and all of these cichlid fishes are endemic. Therefore, they must have evolved rather rapidly. Recent seismic surveys of Lake Victoria and piston cores from its deepest parts by T.C . Johnson et al have surprised everyone: Lake Victoria was completely dry 12,400 years ago. Nor were there deeper "satellite" lakes that could have served as refuges for Lake Victoria's biota during extreme droughts. It is difficult to avoid the conclusion that the present-day 300+ species of cichlid fishes all evolved in less than 12,400 years. This being so, can random mutations -- the accepted source of evolutionary novelty -- have generated so many new species in such a short time? That would be one new species every 40 years or so on the average.

The flat sides and silvery scales of this species make highly efficient mirrors. These fish have learned how to maneuver their bodies so as to reflect bright flashes of sunlight directly into the eyes of their opponents. These intense bursts of light are often enough to burst blood vessels in the eyes of the target fish -- sometimes even stunning it. Pairs of Amazonian angel fish have been observed flitting about in "light-fights" as they attempt to zap each other and avoid optical counterattacks. (Anonymous; Creation/Ex Nihilo , 21:7 , March-May 1999. Attributed to Sydney Morning Herald , October 13, 1998.) Comments.

The gills of other fish are its usual targets, but the orifices of other animals, including humans, are fair game, too.

The short-range "radars" of these fish are marvelously sophisticated, considering the low limb fish occupy on the Tree of Life. In fact, the following introductory paragraph from an article in Nature sounds almost as if it came from a textbook on electronic signal processing. "Behavioural experiments have demonstrated that certain species of fish can perform remarkable analyses of the temporal structure of electrical signals. These animals produce an electrical signal within a species-specific frequency range via an electric organ, and they detect these signals by electroreceptors located throughout the body surface. In the context of one electrosensory behaviour, the jamming avoidance response (JAR), the fish Eigenmannia determines whether a neighbour's electric organ discharge (EOD), which is jamming its own signal, is higher or lower in frequency than its own. The fish then decreases or increases its frequency, respectively. To determine the sign of the frequency difference, the fish must detect the modulations in the amplitude and in the differential timing, or temporal disparity, of signals received by different regions of its body surface. The fish is able to shift its discharge frequency in the appropriate direction in at least 90% of all trials for temporal disparities as small as 400 ns." (Rose, Gary, and Heiligenberg, ...

It is so dark down there that one would expect deep-sea fish to be blind like many cave-dwelling animals. They are not blind; rather many have eyes of fantastic size and novel construction. An unusual feature of some deep-sea eyes is a layered retina. In the conger eel, five layers of photoreceptors are plastered on top of one another. Yet, experiments with conger eel eyes reveal that only one layer of photoreceptors is active at any one time. R. Shapley and J. Gordon, who carried out these experiments at the Plymouth Lab., surmise that the extra retinal layers are being held in reserve, much like the rows of spare teeth found in sharks' mouths.

Called "whitings," these clouds of suspended material are not minor phenomena to file away and forget. Some of the bright streaks are 200 square kilometers in area and can be seen from the Space Shuttle. The source of the whitings has not been determined with certainty. The locals claim that schools of fish stir up the fine, white, calcareous sediments. This is doubted because fish are very scarce in the areas where whitings occur. Another thought was that calcium carbonate was being precipitated directly from the ocean water. Chemical tests showed this to be impossible. A new theory has schools of sharks intentionally raising clouds of bottom sediments to blind fish.

They then drop to the bottom and begin their independent lives, some of which will span a half century or more. "Glochidia that do not hook up with a host fish are doomed. To cover these stakes, the pocketbook mussel and its relatives have evolved a fleshy appendage that flaps in the currents and, to a smallmouth bass, looks like a breakfast minnow. Taking the bait. the duped fish gets doused with glochidia. Another resourceful mussel sends its glochidia out in pulsating little packets resembling worms."

Responding to the article in SF#108 on the Lake Victoria cichlids, A. Mebane called our attention to Lake Malawi. While the Lake Victoria cichlids seem to have evolved a profusion of species in a space of about 12,500 years, those cichlids in Lake Malawi may have done the same in only a century or two. T. Goldschmidt advances this evenmore-abbreviated time scale in his book Darwin's Dreampond . In it, he discusses how the water level of Lake Malawi fell more than 120 meters during the 1800s -- an exceptionally dry period in Africa. Today, the Lake is again high and once more host to isolated rocky islands, each with its own unique complement of cichlid fish; each island has species found nowhere else in the lake. Where did all these species come from, considering that their little islands were bone dry just a century ago? Goldschmidt writes: "Cichlids that inhabited these exposed rocks would have suffocated, unless they had already left for wetter climes. Yet today, species that do not exist anywhere else can be found near almost every rocky island. From an orthodox point of view, the most plausible explanation for this is quite surprising: many color forms as well as biological species developed over a period of less than two hundred years."

When scientists at the Osaka City University asked for reports of unusual animal behavior around the time of the great January 17 quake, over 1,200 people in the Kobe-Osaka area came forth with anecdotes. Some typical pre-quake observations were: Doves flying into walls. Caged birds (Chinese hawk-cuckoos) flying against the sides of their cages. Fish rising to the surface in great numbers. At the port of Shioya, "millions" of gizzard shad turned the surface of the water into silver. Captive stag beetles and turtles emerging from hibernation. And strangest of all, silkworms and fish in ponds orienting themselves in the same directions.

We don't know how upside-down animals get that way; and, obviously, we don't think anyone else does either. Nevertheless, biologists are now discovering some radical things about life that could lead to some real "answers." First, we have a case of genetic material being transferred from a fish to a bacterium. The case at hand is the light-producing bacterium that provides the ponyfish with its luminous organ. In this symbiotic arrangement, the fish somehow passes genetic instructions to its retinue of bacteria. (Lewin, Roger; "Fish to Bacterium Gene Transfer," Science, 227:1020, 1985.) Comment. Perhaps symbiotic relationships are fine-tuned by the mutual exchange of information! Second, the role of viruses in transferring genetic material across species barriers is at last getting some serious attention. (Remember how Fred Hoyle was snickered at for promoting this idea in his books?) D. Erwin and J. Valentine, of the University of California, are now pointing out how a whole colony of "hopeful monsters" might be created en masse by an attack of viruses carrying new genetic blueprints. (And remember how Richard Goldschmidt got the same treatment as Fred Hoyle for suggesting "hopeful monsters" decades ago? (Anonymous; "Gene-Swapping Breaks Barriers in Evolutionary Theory," ...

"Using a dull handsaw, Harvey cut a dead dogwood tree down to a 10-inch stump and then began sawing it lengthwise -- an act of worm fiddling that sounded like someone playing the bassoon, and made the ground purr beneath our feet. "At first, Harvey's sawing seemed to agitate only insects and spiders, but after a while we saw our first fiddled worm. It was 6 inches long, wriggling next to Harvey's boot." Twenty worms at each site are about average with Harvey's fiddling. His fiddled worms are top fish-catchers; the slime they produce even glows in the dark.

These biological lenses focus clicks and other sounds sonar-fashion ahead of the swimming animal, which then listens for echoes from prey and other targets. But what if these bursts of sound could be made very powerful -- could they be employed to stun and disorient prey? Bits of evidence are accumulating to support the theory that some whales and porpoises actually have acoustic stun guns in their foreheads. First, there are visual observations of fish being hunted by whales and porpoises suddenly giving up flight, becoming passive, and almost asking to be snapped up by their pursuers. Second, the stomachs of whales often contain much faster and more mobile prey -- often without any teeth marks. Finally, bottlenose dolphins are known to have the capability of producing bursts of sound five orders of magnitude more intense than their usual navigating clicks. This is more than enough to kill small fish. (Norris, Kenneth S., and Mohl, Bertel; "Can Odontocetes Debilitate Prey with Sound?" American Naturalist, 122:85, 1983.) Comment. Here is another instance of the "problem of perfection." An existing organ of great complexity seems utterly useless of only fractionally developed.

This small, slim, scaleless species of catfish inhabits the Amazon where it preys on other fish, often by invading their gills and feasting on blood and tissue. They also aim much higher on evolution's ladder: they are the only known vertebrate parasites of humans. It is when they prey upon humans that they swim up the wrong streams -- at least their victims think so! Their technique is simple. They detect human urine released by swimmers and follow it right to the source. They don't stop there but insert themselves right into the penis and keep going, sometimes all the way to the bladder. Once inside the penis they erect their spines and cannot be extracted except by surgery. Left alone, they are not only excruciating to the unwise bather but can eventually be fatal.

(SF#89) Snakes, too, it seems, possess an electrostatic sense. The experimental setup for demonstrating the electrostatic-generating capabilities of rattlesnake rattles. Snakes were not blessed with the voltage-generating organs of electric fish, but the simple act of slithering along the ground can generate potentials of 100-1 ,000 volts. In fact, their dry skin seems adapted to generating and retaining electrical charge. Even more curious, laboratory experiments with snake rattles demonstrate that they can generate 75-100 volts when shaken! What is the electrostatic payoff for snakes in their search for prey? It is hard to say. Who has followed hungry snakes around checking on their electric fields? A clue may lie in the ways snakes use their forked tongues in hunting. When following a chemical trail, snakes usually touch surfaces with their flicking tongues. In general exploration, when chemical trails are absent, snakes seem to wave their tongues up and down in a distinctive manner, avoiding surfaces. Herpetologists usually ascribe this action to chemical "sniffing." However, W.T . Vonstille and W.T .

But enter the pigs: "There is firm evidence that pigs can become infected by and may transmit both human and avian influenza viruses not only amongst other pigs but also back to the original hosts. Therefore, pigs seem to be 'mixing vessels' where two separate reservoirs meet and where reassortment between avian and human influenza A viruses occurs, giving rise to the antigenic shift by creating new human pandemic influenza strains with new surface antigens."

Much more devastating to the killerwhale image is an article in Natural History describing the vicious attack of a pack of killer whales on a pod of much larger sperm whales 70 miles off the California coast. To ward off the attack, nine sperm whales had formed a rosette, heads together, with their powerful tails splayed outwards towards the enemy. The killer whales circled the sperm whales ominously. Every so often, one would dash in and tear off a huge chunk of blubber. Eventually, all nine sperm whales floated dead or dying in an ocean of blood.

Are these from the radar screen of a fighter closing in on an enemy aircraft? Or perhaps the electrical signals generated by the fish mentioned in SF#43? Of course the answer is: None of the above. We have a different story to tell. These blips, representing queries and responses, are not generated by human-built radars or by electrical fish, but rather by animals much 'lower' on the evolutionary ladder -- fireflies. This illustration is Fig. 3 in a lengthy review article and carries the following unilluminating caption: "Examples of Entrainment of femme C's (see Table 3) Responses to Multiple Counterfeit Flashes." It seems that we have some sort of electronic warfare between the femme (predatory female fireflies that lure other fireflies with false signals) and the preyed-upon species. The many pages describe all sorts of feints, verification signals, and other stratagems. (Carlson, Albert D., and Copeland, Jonathan; "Communication in Insects," Quarterly Review of Biology, 60:415, 1985.) Comment. It is impossible to do justice to this paper in this short review, but two things should be mentioned: (1 ) Fireflies may be considered "low" on the evolutionary ladder, but ...

Science Frontiers ONLINE No. 45: May-Jun 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Platypus Bill An Electrical Probe The bill of the duck-billed platypus has always looked kind of dumb -- as if Nature flushed with her success with polar bears (below) got careless when designing the platypus! How ignorant we were of Nature's genius. The platypus didn't borrow its snout from ducks but rather from the electric fishes. "That evolutionary enigma, the duckbilled platypus, has more than its egglaying to distinguish it from other mammals. It now appears that in common with some species of fish and amphibians, it can detect weak electric fields (of a few hundred microvolts or less). Not only that, but it uses its electric sense to locate its prey, picking up the tiny electrical signals passing between nerves and muscles in the tail of a shrimp."

But the sky produces other exotic materials, such and blocks of ice and (ugh!) raw sewage. July 26, 1998. Rue, Switzerland. "On Sunday July 26, 1998, at around 9h 45m Central European DaylightSaving Time (7h 45m UT), a Rue farming couple were in front of their house when they heard a whistling sound "like a big rocket on August 1" (Swiss national holiday). They just had time to see a block of ice the size of a "football" pass in front of their field of vision and crash into the tarred path near to their farm. The block broke up into thousands of pieces and the witness recuperated [sic] the largest which was "the size of a skittle." The ice was "very hard" and "snow-colored." "The witness estimated the weight of the ice block at 7-8 kg and the piece he was able to recuperate at 6-7 kg. Unfortunately, he did not think of conserving the block in the freezer, and let it melt near his house after having shown it to his neighbor, who had also heard the noise." Swiss aviation officials claimed they could not identify any aircraft that might have been responsible "because of incertitude over the time of the incident" ...

Science Frontiers ONLINE No. 106: Jul-Aug 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Looking Up Into A Tornado Funnel January 21, 1992. Near Cripple Creek, Colorado. Shortly after 2 PM, while fishing at Skagway Reservoir, D. Mc Gown spotted an ominous cloud formation developing in the west. A horizontal, black cloud rolled toward him. Suddenly, it lifted to reveal a huge, twisting funnel advancing directly at him. He threw himself to the ground, but got a good look up into the interior of the funnel. "The outside of the tornado was spinning so fast my eye couldn't follow it, but the inside was rotating almost lazily. I could see a thousand feet up inside it. Tiny fingers of lightning lined the hollow tube." Passing over him, the funnel bounced across the lake, ripped up some trees, and was gone. (McGown, Dennis; "Letters," Time, 147: 8, June 10, 1996) Comment. The "tiny fingers of lightning" are of great interest to anomalists, because most meteorologists deny that electricity plays any part in tornado activity. Of course, there is often plenty of ordinary lightning in the accompanying storms. An observation very similar to McGown's occurred in Kansas, in 1928. (GLD10-X2 in Lightning, Auroras. For information on this book, visit here .) Today, American meteorological journals are mostly filled with articles on the computermodelling of weather systems, satellite-imaging ...
