Scientists have discovered the first fully warm-blooded fish
It’s one of the most basic biology facts we’re taught in school growing up: Birds and mammals are warm-blooded, while reptiles, amphibians and fish are cold-blooded. But new research is turning this well-known knowledge on its head with the discovery of the world’s first warm-blooded fish — the opah.
One of the two fish from Dandy Orandas that I received yesterday! This fish is often called a telepearl because it is a cross of a telescope and a pearlscale but the japanese name for it is the horyu (穂竜). I can’t wait to have a few of these guys in my pearlscale group.

This is the first known footage of the “Black Seadevil,” a species of anglerfish.
The deep sea anglerfish is famous for the bioluminescent lure the females have on their foreheads, which are meant to draw prey near to their gaping mouths.
This anglerfish was captured on film by a remotely operated vehicle, 2,900 feet below sea level. The Monterey Bay Aquarium Research Institute also captured the fish, but anglerfish don’t usually survive long when brought out of their deep, high-pressure waters.
