|Scientific Name||Pterygoplichthys disjunctivus (Weber, 1991)|
|Common Name||Vermiculated Sailfin Catfish|
|Type Locality||Rio Madeira, Amazon R. system, Restauracao, Amazonas, Brazil.|
|Pronunciation||terry gop LICK thees|
|Etymology||Greek, pterygion, diminutive of pteryx = wing, fin + Greek, hoplon = weapon + Greek, ichthys = fish.|
|Size||430mm or 16.9" SL. Find near, nearer or same sized spp.|
|Identification||Pterygoplichthys can be identified by the number of rays in the dorsal fin. Ten or more dorsal rays (usually more than 10) indicates that it's a Pterygoplichthys. Most other plecos have 8 or fewer rays (in particular the larger Hypostomus species that are most likely to be confused with Pterygoplichthys).
This species is most likely to be confused with P. pardalis. The pattern on the abdomen is the most useful external key: P. pardalis has a spotted pattern, where P. disjunctivus has a vermiculated pattern. For more info see: Zootaxa 1109: 57?68 (2006)
|Sexing||Comparison of the genital papilla in mature fish shows the differences in the sexes to the trained eye. In males this is a small yet thick stump which noticeably protrudes from the fish's undercarriage. In females it is less obvious and is recessed or lies flat with the body.|
