I wish I could find a picture of it, but I can't seem to.Chicago Sun Times wrote:BANGKOK, Thailand -- Scientists have discovered the world's smallest fish on record in an acidic peat swamp in Indonesia, with a see-through body and a head that is unprotected by a skeleton, researchers said Wednesday.
Mature females of the Paedocypris progenetica, a member of the carp family, grow only to 7.9 millimeters [0.31 inches] and the males have enlarged pelvic fins and exceptionally large muscles that may be used to grasp the females during copulation, researchers wrote in the Proceedings of the Royal Society.
"This is one of the strangest fish that I've seen in my whole career," said Ralf Britz, zoologist at the Natural History Museum in London, who helped analyze the fish's skeleton. "It's tiny, it lives in acid and it has these bizarre grasping fins. I hope we'll have time to find out more about them before their habitat disappears completely."
At any rate, here's a picture of the fish I keep, which is small, but not as small as this one newly discovered:
That's an adult female. The males are much smaller and shaped somewhat differently.
