Species

edit

There are currently two recognized species in this genus:[1]

Tridensimilis brevis is distributed in the Amazon River basin in Brazil, while T. venezuelae is distributed in the Orinoco basin in Venezuela.[2] Both species grow to about 2.5–3.0 centimetres (.98–1.2 in) TL.[3][4] T. brevis lives in the sand of shallow rivers and creeks. It is parasitic, entering the gill chambers of larger catfishes. It is also known for entering, probably by mistake, the urethra of mammals urinating under water.[3]
