NOT UNLIKE THE ant-decapitating fly and the satanic leaf-tailed gecko, the fang blenny’s name does not disappoint. This tiny fish wields two massive teeth that it uses to gouge chunks out of much larger fish and, in a bind, scrap its way out of the grasp of a predator. And one particular group of fang blenny even injects venom, just like a snake, to give its attackers that extra what-for.
Researchers have discovered that Atlantic killifish are now 8,000 times more resilient to high levels of toxic waste than other fish, allowing them to survive extreme levels of pollution that would normally be deadly. It sounds like an evolutionary success story, but examples like this are exceptionally rare in the animal kingdom.
There are thousands of ships sailing the seas to catch the fish you eat, and now you can watch them sail the ocean in almost real-time on this interactive map.
Smithsonian Channel’s Secrets of Shark Island is a wonderful documentary about the ecosystem in the waters around the Revillagigedo Islands, a group of four volcanic islands 240 miles off of Mexico. Because it’s “the only natural juncture for miles” in the Pacific Ocean, there’s a lot going on around there. Most scarily, a shit ton of migrating sharks. My God, just look at all them.
Researchers have used compounds found in algae and reef fish mucus to create a material that naturally blocks harmful UV rays, according to a paperpublished recently in ACS Applied Materials & Interfaces.
The car-tire-size opah is striking enough thanks to its rotund, silver body. But now, researchers have discovered something surprising about this deep-sea dweller: It’s got warm blood.
