Male parr (parr are young sal-mon that have not yet been to sea) are becoming sexually precocious in large numbers. The small males have up to 20% of their body weight allocated to testes and, in consequence, seem to be bulging from full meals. Actually, they are ready to dart in under mature spawning salmon and fertilize some of the newly laid eggs. Experiments show that the parr are rather successful in their furtive endeavors. The question at hand is why the parr are developing precociously when there are sufficient mature male salmon around to do the job. (Montgomery, W. Linn; "Parr Excellence," Natural History, 92:59, June 1983.) From Science Frontiers #30, NOV-DEC 1983 . 1983-2000 William R. Corliss ...

Science Frontiers ONLINE No. 51: May-Jun 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Giant Fish Reported In China "In August, 1985, both AP and UPI wired dispatches from Beijing, People's Republic of China, reporting the discovery of enormous red fish in a remote lake in the Xinjiang Autonomous Region of northwestern China. The report, originating with the Xin-hua News Agency, quoted Professor Xiang Ligai, of the biology department of Xinjiang University, as stating: 'The mystery of monsters in Lake Hanas has been solved.' The fish, he stated, were a giant species of salmon reaching a size of over 30 feet." The ISC Newsletter originally declined to relay the AP/UPI stories without confirmation by more responsible Chinese sources. Then, in April of 1986, the official Chinese Magazine China Reconstructs, presented a short article on the subject, which included additional information. For example, large nets have been destroyed and horses going down to the lake to drink have disappeared! (Anonymous; "Giant Fish Reported in China," ISC Newsletter, 5:7 , Autumn 1986.

... aggregations of 5-17 males were observed formed around these individual attractive males, which we have termed 'she-males.' In competitive mating trials, she-males mated with females significantly more often than did normal males, demonstrating not only reproductive competence but also a possible selective advantage to males with this female-like pheromone." In the competitive mating trials, the she-males were successful in 29 out of 42 trials. The normal males won out in only 13! The authors ask the question: Why aren't all males she-males given such an advantage? (Mason, Robert T., and Crews, David; "Female Mimicry in Garter Snakes," Nature, 316:59, 1985.) Comment. Among the fishes, bluegills and salmon (and probably many others) have female-appearing males competing with normal males. From Science Frontiers #41, SEP-OCT 1985 . 1985-2000 William R. Corliss ...

... interest is usually focussed (by the media) upon the supposed monsters in Loch Ness, Lake Champlain, the Chesapeake Bay, etc. Actually, an immense body of sea serpent reports also exists. B. Heuvelmans collected many of these in his 1965 classic In the Wake of the Sea-Serpents. P.H . LeBlond, a professor at the University of British Columbia, is extending Heuvelman's work, concentrating on the thousand miles of Pacific Coast between Alaska and Oregon. Since 1812, there have been 53 sightings of sea serpents or other unidentified animals along this narrow strip of ocean. Some of these are very impressive. Take this one for example: "In January 1984 a mechanical engineer named J.N . Thompson from Bellingham, Washington, was fishing for Chinook salmon from his kayak on the Spanish Banks about three-quarters of a mile off Vancouver, British Columbia, when an animal surface between 100 and 200 feet away. It appeared to be about 18-20 feet long and about two feet wide, with a 'whitish-tan throat and lower front' body. It had stubby horns like those of a giraffe, large (' twelve to fifteen inches long') floppy ears, and a 'somewhat pointed black snout.' The creature appeared to Thompson to be 'uniquely streamlined for aquatic life,' and to swim 'very efficiently and primarily by up and down rather than sideways wriggling motion...'" LeBlond and biologist J. Sibert have analyzed all of the 53 sightings in a 68page report entitled "Observations ...
