Minnesota River Monster Tale

I guess the moral to this story is that corncob wine and river monsters don't mix.

In any case, it doesn't sound like anything reptilian. Actually, except for the size, it sounds like one of the lampreys, though the native species in the Red River barely reach a foot in length, if that. But then, the corncob wine might have incited a little exaggeration...

A Strange Fish from Yap

I recently ran across mention of a "mystery fish" from the Micronesian island of Yap, in Kenneth Brower's 1983 book, A Song for Satawal. Brower mentions that in a paper on ethno-ichthyology of the island, Dr. Margie Falanruw listed a fish the Yapese call galuf nu medai, translated as "monitor lizard of the sea." She noted: "Lives in mangroves, head like a crocodile, caught at night, has lizard-like skin and red meat that tastes like salmon. Three to four feet long."

It sounded interesting, so I contacted Dr. Falanruw to see if it was actually unknown. She was kind enough to provide an identification of the fish: Cymbacephalus beauforti, or crocodilefish.

But, she notes that she is currently working on the description of a new reptile from the region, so zoological discovery continues, even in a fairly well-known part of the world.

The "Giant Prehistoric Minnow"

Years ago, I came across Lost Legends of the West, by Williams & Pepper (1970). They briefly mention the story of a man in the early 1960s who caught a "giant prehistoric minnow" in Lake Mojave, which excited wildlife officials. The story is repeated in the 2007 book, Weird Las Vegas and Nevada. When I posed the question of the species of the fish on the old CZ list in 1999 (actually, I see that Matt Bille had previously queried on the subject there), Jack "Rabbit" noted that it was probably the Colorado squawfish, Ptychocheilus lucius (now called the Colorado pikeminnow). With recent advances in search capabilities, it's now possible to confirm this identification, and I can point to a closer source to the story. Desert Magazine from August 1963 gives a few details in its article on Lake Mojave. The court battle (with victory for the fisherman) for the 1960s fish's remains (noted in Lost Legends) isn't mentioned, so I am uncertain as to whether it is apocryphal. Today, of course, there would be no legal grounds for possession of an endangered fish, but as Federal protection wasn't even available until the ESA in 1973, I suppose such a court case could have happened.

"This foreshortening of the color spectrum under the waves was also assumed to correspond to a narrowed field of vision in fish, said the study's lead researcher in an interview." ...
"Looking through a filter while scuba diving that blocked out the brighter green and blue light waves, leaving only red ones, they suddenly saw a whole universe of sea creatures glowing various hues of cherry, crimson, ruby and rust."

"The fish has been named Chromis abyssus in honour of the TV series.
"The story is a more complicated one, however, because Dr Pyle first saw this fish more than a decade ago. Other researchers, too, had sightings, including one from a small submersible and another from a Remotely Oerated Vehicle (ROV).
"It was during the BBC filming, though, that nine specimens were finally captured, allowing for an official scientific submission this year."

"Dr. Jeff Drazen detailed, 'One of the animals we observed on this expedition was a fish called an eel pout. We don't know the species for certain, but it belongs to a family of fishes that have never been documented in the Hawaiian Islands.'" ...
"These were at a depth of 10,000 feet. ... 'They were attracted to the bait and they seemed to eat some of the other animals that were also attracted,' said Drazen."
"The research team plans to head back out to the Northwest Hawaiian Islands next year to catch some specimens-of eel pout and possibly other fish!"

Someone in North Carolina thinks they may have seen an unidentified species of small fish:

"Abe Nail has seen some very strange fish swimming in Phillip’s Creek. Nail said the fish he saw were a bright, scarlet red with white fins, and were about 2 to 2 ¼ inches long.
"Nail said the fish come around for a few weeks in late May and early June.
"Nail thinks the fish may turn this bright red color as part of their mating ritual. He said they turn back to a drab orange after a few days." (News source.)

Given that there are probably quite a few small cyprinids in NC, I'd suspect a little-known species over an unknown species, and you'd probably need a specialist to determine that, but there was a new species of fish described in WV earlier this year, so you never know...

New Fish in West Virginia

A new species of darter has been discovered in West Virginia. (News source.)

"A new species of fish has been discovered in the lower Elk River near Charleston by a West Virginia University professor. Stuart Welsh, assistant professor in the Wildlife and Fisheries Resources Program in the Davis College of Agriculture, Forestry and Consumer Sciences, named the new species Crystallaria cincotta, or 'diamond darter.'
"His findings were recently published in Zootaxa, an international journal for animal taxonomists. The diamond darter is a close relative of the crystal darter (Crystallaria asprella), a small fish found in the drainage basins of the Mississippi River. Diamond darters are translucent; adults range from 3-5 inches long."

Search on for Strange Fish

Another case of an unwitting cryptozoological investigation in mainstream science: sightings and photographs of a strange anglerfish have been taken, but the species (perhaps the family) is still unknown. (Eurekalert.) [Image: M. Snyder, starknakedfish.com/divingmaluku.com]

"The fish, sighted in Indonesian waters off Ambon Island, has tan- and peach-colored zebra-striping, and rippling folds of skin that obscure its fins, making it look like a glass sculpture that Dale Chihuly might have dreamed up. But far from being hard and brittle like glass, the bodies of these fist-sized fish are soft and pliable enough to slip and slide into narrow crevices of coral reefs. It’s probably part of the reason that they've typically gone unnoticed – until now." ...
"Husband and wife Buck and Fitrie Randolph, with dive guide Toby Fadirsyair, found and photographed an individual Jan. 28 in Ambon harbor. A second adult has since been seen and two more – small, and obviously juveniles – were spotted March 26, off Ambon. One of the adults laid a mass of eggs, just spotted Tuesday." ...
"The newly found individuals have no lures so they seek their prey differently, burrowing themselves into crevices and cracks of coral reefs in search of food." ...
"With its unusual flattened face, the fish's eyes appear to be directed forward, something Pietsch says he's never seen in 40 years as an icthyologist, a scientist who studies the structure, classification and habits of fishes. Most fishes have eyes on either side of their head so that each eye sees something different. Only very few fishes have eyes whose radius of vision overlaps in front, providing binocular vision, a special attribute well developed in humans that provides the ability to accurately judge distance." ...
"Whether the new fish represent a new family will entail DNA testing and a close examination of a specimen, says Pietsch, whose anglerfish work is currently funded by the National Science Foundation. Scientists have already described 18 different families of anglerfishes and this is probably a 19th, Pietsch says. Families are large groupings, for example, all dog species belong to the larger family that includes wolves, coyotes and, even, hyenas. One can see an example of an anglerfish family, the one named Antennariidae, at http://www.tolweb.org/Antennariidae/21993, a part of the Tree of Life Web project.
"When only a single fish had been sighted, Randolph and Andy Shorten, co-owner of Maluku Divers, kept the find quiet to protect the animal. With more individuals being found, and having a better idea of where to look to find others, the two became comfortable enough to post images on the firm's Web site, see http://www.divingmaluku.com/new-frogfish."

Korean Scientist on the 'Tianchi monster'

A North Korea scientist has suggested that the images of the 'Tianchi monster' captured by a Chinese photographer are large trout, the offspring of fish introduced into the lake by North Koreans 40 years ago. From the news:

"77-year-old Kim Li-tae said during an interview with the Choson Shinbo, a newspaper published by the General Association of Korean Residents in Japan, that he was one of the North Korean researchers who released nine trout into Tianchi Lake, located on Changbai Mountain, on July 30, 1960. At a later date they released other species of fish such as carp and mosquito fish into the lake." ...
"In 2000, the Korean researchers did experimental tests on 'Tianchi trout' found in shoal waters that measured 85 centimeters in length and weighed 7.7 kilos, but they've never been able to test trout from the deeper waters of Tianchi Lake. The 'Tianchi monster' that Chinese photographer Zhuo Yongsheng, who works for a local TV station run by the administration office of the nature reserve at Mount Changbaishan, Jilin Province captured on film last month, might be a 'Tianchi trout' from the deep of the lake, Kim said."

Albino

A foot-long albino ratfish was caught during a University of Washington research project off Whidbey Island. From the Eurekalert:

"'Ratfish usually hang out in places with soft, muddy bottoms,' says Jon Reum, the aquatic and fishery sciences doctoral student who found the albino ratfish during a UW research project. 'The typical ratfish in Puget Sound is brown or black with a smattering of white spots so it blends in with the sediments.'
"This fish was almost pure white with a crystalline layer near the surface of its skin that gave it a silvery sheen." ...

"After the albino ratfish was caught the researchers attempted to keep her alive in a bucket of water but, in spite of boards placed over the top, she managed to flip out of the bucket onto the deck during the night. She is now preserved and part of the UW Fish Collection, which has 82 other ratfish specimens, ranging from eggs to full-grown adults. The collection, which focuses on North Pacific and Bering Sea fishes, is needed by researchers on and off campus to identify species and to understand fish biology and conservation."

L. Alexandrei described - new Brazilian Snapper

Lutjanus alexandrei has been described recently in the paper “A new species of snapper (Perciformes: Lutjanidae) from Brazil, with comments on the distribution of Lutijanus griseua and L. apodus” by R.L. Moura and K.C. Lindeman (in Zootaxa 1422: 31-43: 2007).

This new endemic species from Brazil has been misidentified in the past as other species, including L. apodus (schoolmaster), L. jocu and L. griseus (gray snapper) . This brings the total known western Atlantic species of snapper to 12.

First known to be different in 2003, the species was further acknowledged as being unique through subsequent morphological examinations in the field and museum specimens.

Having a reddish body and fins, blue spots, and white lines along its surface, this snapper is a rather stunning fish indeed. Named after naturalist Alexandre Rodrigues Ferreira, this new snapper has had the common name of Brazilian Snapper proposed.

Galaxy rasbora placed in new genus

Galaxy rasbora placed in new genus


"Microrasbora sp 'Galaxy' has been officially described and placed in a new genus. Tyson Roberts today described the new species as Celestichthys margaritatus in a paper in the Raffles Bulletin of Zoology. He has also given the fish the new common name of Celestial pearl danio. Roberts says that the new species is a member of the cyprinid subfamily Danioninae and is most closely related to two danionins from Inle Lake in Myanmar, Microrasbora rubescens and "Microrasbora" erythromicron.


"Prior to its official description, the fish was only tentatively considered a member of the Microrasbora genus, on account of its similarity to M. erythromicron. Roberts believes that Celestichthys margaritatus is so different to other Microrasbora that it warrants a genus of their own, possibly along with "Microrasbora" erythromicron. The fish, which was discovered in August 2006, was first covered by Practical Fishkeeping in September and featured in the Interesting Imports column in the December 2006 issue of the magazine."
