A small, cave-dwelling fish found in some parts of Mexico. Originally thought to be extinct, small colonies continue to be discovered. Very little is known about how these fish live, but constant inbreeding caused by extreme isolation has taken its toll on their physical and mental aptitude. This is one of the reasons scientists believe the diatribe population is so small.
"As far a mating goes, only a few of these diatribes seem to have the physical ability and desire to understand what it is they are supposed to be doing. It's fascinating, but also quite sad."--Scientist
