Size 800mm or 31.5" SL. Find near, nearer or same sized spp.
IdentificationOnly smaller fish are similar to the Asian Chaca Frog mouthed cats. Otherwise this is an instantly recognisable fish.
SexingUnknown
General RemarksA very interesting fish as it appears to be a very good example of parallel evolution. Compare with catfish of the Asian genus Chaca. The English common name 'Pac Man Catfish' is interesting as it obviosly and accurately compares this species with the yellow, large-mouthed and pellet gobbling arcade game character, but also it is a bastardisation of the Brazilian name for the fish, Pacamã. Furthermore, the source of that may be that Paco is a common nickname for Francisco (this species is only found in the Rio Sao Francisco) albeit commonly used in Spanish as opposed to Portuguese (typically Chico).
