[2] [3] Since then, these genera were recognized as synonyms of Pterygoplichthys by Armbruster, as the few differences between the genera were not deemed great enough to validate Glyptoperichthys and Liposarcus, and that recognizing ...

[12] Flathead catfish are a benthic fish species meaning they are a fish which prefers to lay on the bottom of a body of water.
