Peaceful Harlem Meer has long been a place to cast a fly or a worm-baited hook in hopes of catching something in the panfish category—yellow perch, small bass, and crappies—but several fishermen have been reporting surprise or downright terror when they have latched into toothy gamefish with pugnacious attitudes and mouthsfull of razor-sharp teeth. Tucked into the northeastern corner of New York City’s Central Park, Harlem Meer is an 11-acre manmade body of water created started …

Some are gentle giants, feeding on algae and plankton, others are voracious feeders who grab animals from the banks and pull them into the water. These fish have what’s known as “indeterminate growth”, growing larger as long as they live without disease or predation. So the larger fishes …

Striped Surgeonfish Photograph by Paul Nicklen The striped surgeonfish is an attractive Indo-Pacific reef fish that’s best handled with care because its caudal spine is venomous. Scientists believe that the world’s seas hold some 1, 200 different venomous fish species and estimate that they injure about 50, people per year.

Paleontologists have discovered a unique backbone structure, never seen before, in the fossil remains of a fish that lived 240 million years ago. This long-bodied fish has the scientific name Saurichthys curionii. Its vertebrae had twice the number of bony extensions called vertebral arches than similar fish, which formed its elongated body. However, as a result of its backbone structure, this primitive predatory fish lacked the flexibility of today’s long-bodied fish – for example …

A science team in Australia has the first clear evidence that damsel fish can change the size of both a false eye and their real eye to maximize chances of survival. Small prey fish can grow a bigger false eye on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new scientific research has found. Researchers from Australia’s ARC Centre of Excellence for Coral Reef Studies (CoECRS) have made a world-first discovery that, when …

One of the more popular exhibits at The Tech Museum of Innovation in San Jose is the wetlab. This is where museum visitors get to add the green fluorescent protein (GFP) gene from jellyfish to bacteria to get the bacteria to glow green. The 20, or so people who do this each year get to learn about how genetically engineering bacteria can help to create important medicines like EPO, insulin and growth hormone. The exhibit is getting a little long in the tooth so I was looking …
