11. Belongs To The Elasmobranch Family

Blackmouth catsharks, the species that our skinless wonder belongs to, are actually part of the large Elasmobranch family of fish. This family of fish includes sharks, sawfish, and rays – and are mainly known for having a skeleton made from cartilage instead of bones.

The Elasmobranch fish have been around for a long time – dating all the way back to the time of the dinosaurs! This puts them to be as old as 145 to 66 million years ago – that’s quite something! Elasmobranch fish are also known for having broad, flattened gills, from which they also derive their name – in Ancient Greek.- Elasmo means ‘plate’, while branchia translates to ‘gills’.
