Tag: Sharks, Skates and Rays (Elasmobranchii)

Elasmobranchii is one of the two subclasses of cartilaginous fish in the class Chondrichthyes, the other being Holocephali (chimaeras).

The main features that set Elasmobranchs apart from the vast majority of other fish groups are the lack of a swim bladder, a cartilaginous skeleton and skin comprising tiny "tooth-like" structures called dermal denticles, rather than the typical scales found on most other fish species.

Due to the relatively small number of species found in local waters, i decided to group the Sharks, Skates and Rays together.

I've also added the family group to all three categories (Reef, Pelagic and Benthic) as there are species which inhabit one particular zone but not the others eg. Stingrays are typically Benthic whilst Whale Sharks are definitely Pelagic.
