Uniformitarian geologists have steadfastly maintained that such diatomaceous-earth deposits require millions of years to form as the tiny skeletons sink slowly to the sea floor. At Lompoc, however, embedded in the thick layer of diatomaceous earth is the fossil of a large whale apparently standing on its tail. How could this whale fossil have maintained its position and integrity over hundreds of thousands of years as it was buried millimeter by millimeter? Wouldn't the bones have been quickly scattered? Creationists have pointed to this whale as proof that the Lompoc diatomaceous-earth deposit was formed catastrophically, interring the whale almost instantaneously, and burying doctrinaire uniformitarianism at the same time. (Creationists want to "shorten" geological time to fit Biblical schedules.) But was the whale really entombed on its tail? Creationist geologists studied the Lompoc deposit and put a different slant on the story but not on its ending. "Contrary to some reports that have circulated, the 80-90 ft (24-27 m) long fossilised baleen whale found in April 1976 in an inclined position in a diatomite unit in the Miguelito Mine at Lompoc, California, was not buried while 'standing on its tail'.

These mammals are effectively toothless for predatory purposes. In fact, some marine biologists speculate that they secure their slippery prey by suddenly vacuuming them up by actuating a pumplike tongue. (AR#2 ) But how do the beaked whales find their prey in the first place? With their sonar, of course. But these superbly streamlined animals lack the huge external ears of the sonar-using bats. How do they detect the weak echoes bouncing off fleeing fish? P. Zioupos and J. Currey, at the University of York, have drawn attention to the rostrum bone that forms the beaklike upper jaw of Blaineville's beaked whale. At 2.7 grams/cubic centimeter, this bone is 50% denser than the average mammalian bone. "The bone also turned out to have unique chemical properties. It contains 35 per cent calcium by weight -- 13 per cent more than the highest value known previously. Using microscopes, the team showed that the bone is riddled with tiny tunnels. containing highly concentrated minerals." The channelled nature of this bone make it very brittle, making it unlikely that it is used as a ram in mating bouts. Zioupos and Currey propose that this uniquely structured bone is really an acoustical pipe for the beaked whales' sonar signals. (Barnett, Adrian ...

The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R . Johnson, is the northeastern Bering Sea, where sensitive side-scanning sonar has sketched large numbers of pits and furrows in the shallow sands. The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried organic matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C. Hans, and Johnson, Kirk R.; "Whales and Walruses as Tillers of the Sea Floor," Scientific American, 256:112, February 1987.) ...

McLeod, a paleontologist at the Los Angeles County Museum of Natural History, has been studying the bones of a 10-million-year-old whale found in a backyard in Southern California. It is claimed that these bones "will fill an im portant gap in (the) knowledge of the evolution of whales." Actually, the opposite seems to be the case. "One of the interesting things about the discovery is that it appears 'this guy didn't follow the same evolutionary path as living whales,' McLeod says. Sperm whales today have well-developed teeth only in the lower jaw, whereas the fossil whale shows evidence of very large, very welldeveloped teeth in both upper and lower jaws." (Tyndall, Katie; "A Whale's Legacy," Insight, 49, June 15, 1987. Cr. C. Stiles.) Comment.

Here are found free-living bacteria, tube worms, molluscs, and several other species that prosper without the benefit of photosynthesis. These chemosynthetic, thermal-vent communities are separated by thousands of kilometers of sea-floor "desert." Yet, the species involved are similar worldwide and must, at some time, have crossed these wide, forbidding expanses. One possible mechanism for this mysterious dispersion came in 1987, when the research submersible Alvin chanced upon the remains of a 21-meter whale at a depth of 1,240 meters off California's coast. The whale's skeleton was covered with bacterial mats like those at the hydrothermal vents. Also sustained by the carcass were mussels, snails, and worms; all in all, a community much like those at the vents. Furthermore, many of the species partaking of the whale's energy and chemical resources are not normally found in that part of the Pacific. Subsequently, more "whale falls" with attached biological communities were found elsewhere. Calculations suggest that whale falls are more common that one might suppose -- perhaps occurring with average spacings of only 25 kilometers. They could very well be the stepping stones that allow hydrothermal vent communities to disperse across the ...

Kirschvink, of the California Institute of Technology, has plotted the hundreds of beachings of whales and dolphins along the U.S . east coast. He finds that these cetaceans tend to run aground at spots where the earth's magnetic field is diminished by the local magnetic fields of rocks. These coastal magnetic lows are at the ends of long, continuous channels of magnetic minima that run for great distances along the ocean floors. Kirschvink believes that the stranded whales and dolphins were using these magnetic troughs for navigation and failed to see the stop sign at the beaches and ran aground. The mag-netic troughs in this view are superhighways for animals equipped with a magnetic sense. If Kirschvink's theory is correct, the magnetic sensors of the whales and dolphins are extremely sensitive, because the deepest magnetic troughs are only about 4% weaker than the background magnetic field. Magnetite crystals have been found in birds, fish, and insects, where they are thought to contribute to a magnetic sense of some sort. So far, no magnetite has shown up in whales and dolphins.

Whales subconsciously strand and kill themselves in order to maintain their populations at optimum levels! Well, the dozen or so other theories that have been advanced to account for whale strandings haven't been much better. M. Klinowska thinks that she has some clues indicating a better theory. First, all whale strandings (in Britain, at least) occur where magnetic field contours are perpendicular to the shoreline. Second, strandings are also correlated with irregular changes in the magnetic field. You will see the significance of these facts after you hear her theory. "Cetaceans use the total geomagnetic field of the Earth as a map. A timer, also based on this field, allows them to monitor their position and progress on the map. They are not using the directional information of the Earth's field, as we do with our compasses, but small relative differences in the total local field. I arrived at this explanation after a detailed analysis of the records of strandings in Britain, but it has so far been confirmed by two groups working in the U.S . Similar work is in progress in other parts of the world. "The total magnetic field of the Earth is not uniform. It is distorted by the underlying geology, forming a topography of magnetic 'hills and valleys.' My analysis shows that the animals move along the contours of ...

Ford is the curator of marine mammals at Vancouver's Public Aquarium. For years, he has been listening to killer whales converse as they hunt along the coast of the Pacific Northwest. About 350 whales in the area are divided into two communities, each of which is subdivided into several pods. Each pod has its own dialect of sounds used in communication. Some of the dia-lects are regional, like Bostonian or Texan; others are more divergent, like English and Japanese. This discovery promotes killer whales to the level of some primates and harbor seals. Usually, Ford says, the sounds made by animals are determined genetically.

They're talking about intricate, stylized compositions - some longer than symphonic movements - performed in medleys that can last up to 22 hours. The songs of humpback whales can change dramatically from year to year, yet each whale in an oceanwide population always sings the same song as the others. How, with the form changing so fast, does everyone keep the verses straight? Biologists Linda Guinee and Katharine Payne have been looking into the matter, and they have come up with an intriguing possibility. It seems that humpbacks, like humans, use rhyme." Guinee and Payne suspect that whales rhyme because they have detected particular subphrases turning up in the same position in adjacent themes.

Sophisticated music predates the advent of modern humans by tens or hundreds of million years. Whales and birds filled the ocean and primeval forest with song long before our hominid branch sprouted on the Tree of Life. As a matter of fact, our closest relatives, the great apes, sing not at all. Somewhere in the hominid genome "music" genes reside, unexpressed in the apes, but somehow triggered into activity in the human line. We have learned recently that the Neanderthals manufactured bone flutes as far back at 53,000 years. They may not have been able to speak to one another in words, but they had the language of music. Their music, and ours, may have been entrained in genes inherited from nonhominid ancestors that lived 60 million years ago, but which have been suppressed in primates until Neanderthals and modern humans came along. You may wonder where this argument is taking you. It goes back at least 60 million years to when the cetacea (whales and dolphins) split off from the evolutionary track leading to humans. It may even go back farther to when birds split away from the reptilian line. The music of birds and whales incorporate some of the complexity and sophistication of Beethoven's Fifth. The genes that have led to such musical talents may be ancient indeed, as speculated in the Science article under review. The authors go ...

They are usually portrayed as gentle, intelligent, human-friendly marine mammals that dine only on fish. Lately, though, we have been reading that Alaskan killer whales have been snacking on those cute little sea otters. 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. The "gentle-giant" portrait of the killer whale is tarnished further in the Antarctic where they habitually dine on the lips and tongues of minke whales, then leave them to die.

Only the male humpbacks sing, and then only during the mating season. In contrast, the songs of blue whales are exceedingly dull. They consist of only five notes repeated in various combinations. Since both sexes sing most of the year, the songs of the blue whale probably have nothing to do with reproduction. Then, why do they sing? A clue to the purpose of the blue whales' songs is found in their precision timing. One note is sung every 128 seconds. Furthermore, these notes (sound pulses) carry for hundreds of kilometers. C. Clark, a Cornell scientist, believes these notes are really sonar pulses used for fixing a whale's location. Echoes returned from distant seamounts, continental shelves, and other undersea topography enable the whales to map their positions within the wide ocean basins as they wander far and wide. (Hecht, Jeff; "Rhythm of Blues Charts the Ocean Depths," New Scientist, p. 19, June 20, 1998.) Comment.

Tokerau Beach, North-land, New Zealand. A pod of 80 pilot whales ran aground and were stranded by the ebbing tide. Local townspeople followed a new technique developed for aiding stranded cetaceans. They waded out, talking soothingly to the whales, and keeping their skins wet. When the tide came back in and refloated the whales, the New Zealanders turned them around and tried to guide them to deeper waters. Sometimes refloated cetaceans just turn around and reground themselves again, but this time the pilot whales were fortunate. A school of dolphins fishing offshore somehow apprehended the situation and swam into the shallows around the pilot whales. The dolphins then guided them out to sea. 76 of the pilot whales were thus saved. In a similar incident 5 years earlier at Whangarei harbor, a helicopter followed the dolphins and whales several miles out to sea, confirming interspecies aid. Such stories are reminiscent of those where drowning humans are helped by dolphins. (Anonymous; "Dolphin Pilots," Oceans, 17:50, 1984.) Reference.

Yet, these whales have no problem catching and consuming their swift, fishy prey. Apparently, they first stun their dinners acoustically and then suck them in with the pump-like action of their muscular tongues. (AR#2 and BMA25 in Mammals I) Occasionally, whalers have caught sperm whales with congenital, grossly twisted jaws that are completely useless in hunting, yet these animals thrive on a rich diet of fast, elusive squid. A. Werth of Hampden-Sydney College theorizes that these much larger cetaceans also suck in their prey just like the beaked whales. Sperm whales also generate sound pulses so strong that they can very likely stun the giant squid, their preferred food, as they pursue them with their sonar in miledeep blackness.

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.

Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on the evolution charts. In other words, they were probably not random, unlucky mutations; rather, something more profound. Neo-Darwinists are quick to explain that these afflicted species may have originally frequented shallow waters where sensitivity blue light was not so important.

It did not seem to be in much of a rush, and it swam very slowly. The water was very clear, and 5 to 10 feet behind the hump, about 5 to 8 feet below the surface, I could see its tail. The tail was forked and horizontal like a whale's , and it was 4 to 6 feet wide. As the hump submerged, the tail came to the surface until its tip poked above the water about a foot...About 4 or 5 minutes passed from the time it bumped me until the time it swam from view.'" Ogopogo's estimated length was 25-30 feet; breadth, 3-4 feet. No fins or hair were seen. The animal was serpentine -- seemingly without a neck. Its vertical undulations and horizontal tail procclaimed it to be a mammal, possibly a primitive type of whale.

New varieties of the culprit -- called a calicivirus -- have since turned up in diverse hosts: whales, cats, snakes and even primates. To reach such a variety of hosts, they either jump from organism to organism, Smith proposes, or they escape from bubbles popping on the ocean surface, waft ashore and enter a food chain. If he is right, the seas may be a bottomless reservoir for viruses -- and our attempts to combat diseases on land may be nullified by legions of new strains waiting to come ashore. In fact, some flu viruses are said to be spread by wild ducks." (Anonymous; "Are the World's Oceans a Viral Breeding Ground," Science Digest, 92:20, February 1984.) Comment.

Caddy" is short for Cadborosaurus , the speculative sea animal seen rather frequently off the British Columbia coast and as far south as Oregon. Professor P. LeBlond, University of British Columbia, recently presented a paper on Caddy at a joint meeting of the Canadian and American Societies of Zoology. Of all the supposed sea serpents, Caddy seems closest to respectability. Not only are there many sightings on record, but the remains of a 3-meterlong carcass of an apparent juvenile specimen of Caddy was discovered in the stomach of a sperm whale. Adult Caddys are about 7 meters long. "The descriptions [of Caddy] are generally similar. They suggest a long-necked beast with short pointed front flippers, a horse-like head, distinct eyes, a visible mouth and either ears or giraffe-like horns. Often Caddy is described as having hair like a seal, and sometimes a mane along its neck." Most interesting is Caddy's body hair, which implies a mammal rather than a reptile. But if it is a mammal, how does it get air, since it surfaces so rarely? Some have suggested that the giraffe-like horns are snorkels! But E. Bousfield, a colleague of LeBlond, thinks that the tubercules reported along the animal's back might be gill-like tissues that would allow a mammal to extract oxygen from seawater! With so ...

Of course, we recognize that whales and other cetaceans also seem to "talk" to one another, and that other animals employ their sense of smell for relaying messages. But most of us do not realize that lowly fireflies congregate to communicate en masse, with untold thousands of individuals cooperating in huge synchronized light displays. In reading some of the descriptions of these great natural phenomena, one recalls the light displays used to communicate with the aliens in the movie Close Encounters of the Third Kind . J. Buck has been studying flashing fireflies for over half a century. In fact, his first review paper was published in 1938. Buck has now brought that paper up to date in the current Quarterly Review of Biology with a 24page contribution. It is difficult to do justice to this impressive work in a newsletter.

Why did they go all the way to the ends of the closed passages, given their excellent echo-location systems? Pertinent here is the discovery of skeletons and recent carcasses of green turtles in similar situations in underwater caves in Indonesia.

... that much biological evolution proceeds not in minute steps but by large jumps or saltations. Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas. Nevertheless, many biologists think that species are somehow frozen in time by environmental forces that keep them from straying from their little niches. This being so, paleontologist D. Jablonski, University of Chicago, asks: If stability is the rule, how do you get large-scale shifts in morphology? How do you get from funny little Mesozoic mammals to horses and whales?

"New field measurements and computer analysis link the gigantic ground drawings to the Andean tradition of dividing up space and time by cycles of the Milky Way. By including ethnoastronomy in the analysis, these conclusions differ from [those of] previous researchers. The first hypothesis tested was that the figures could be considered like labels to the lines. Of the twenty-seven figures, ten are birds, three are whales, and two are seaweed plants. Theodolite measurements revealed a non-random distribution of the directions of lines attached to look-alike figures. The second test showed a physical relationship of present-day Andean plant and animal figures imagined as silhouettes in dark spots along the Milky Way to figure-lines pointing to the rising and/or setting of the same Andean figure 2000 years ago. In the third test, all other lines extending to the desert horizon from a figure center keyed into dark spots and bright stars along the Milky Way at the same Local Sidereal Time in the same year.

To descend deep for long periods, they have evolved a diving adaptation radically different from that employed by the dolphins, whales, and seals; namely, rectal gills.

We are talking 50-foot sharks and larger here; sizes that make the hero (or heroine) of the Jaws series seem minnow-like. All of these hints come from the Pacific and focus on the possible survival of the shark Carcharodon megalodon , a monster relative of the great white shark. Megalodon is thought to have met its demise a million or so years ago. The word megalodon means "big tooth," and indeed the fossil teeth of this monster approach 6 inches in length. Sharks sporting teeth of this size could be as long as 50 feet. Measurements of the manganese dioxide layers accumulated on megalodon teeth dredged up from the seafloor suggest that it might actually have survived the Ice Ages and terrorized the Pacific as late as 10,000 years ago. Actually, some unfossilized teeth 5 inches long have been brought up by dredges, implying an even more recent existence. Do scuba divers have anything to fear today?
