| Range of the onefin catshark | |
The onefin catshark (Pentanchus profundicolus) is a relatively unknown species of marine catshark, and part of the family Scyliorhinidae. It is the only member of its genus. The only specimen recovered was from the Mindanao Sea near the Philippines.[2] It is classified as harmless to humans and of least concern to the IUCN redlist.[3]
Description & behaviour
The Onefin catshark is a small, dark brown shark. It only has five pairs of gills and one dorsal fin near its tail. It has an elongated and flattened head which is pointed at the nose. Its anal fin is notably long - larger than the pelvic and dorsal fins. The caudal fin is also elongated.[2] The maximum known length of the catshark is 51cm.[3]
They tend to live between depths of 673m to 1069m.[2]
Etymology
The scientific name 'Pentanchus' is possibly a mix between the word 'penta' from the greek 'pente' meaning five, and 'anchus' a possible abridgment of the greek 'branchos' meaning gill. This would refer to the five pairs of gills the shark has, which would make the shark unique if it were a hexanchoid - the authors mistakenly believed this to be the case.[3]
