Thornback Rays (Raja clavata) are identifiable by their thorny plates along their tail – usually two. Their body is brown in colour with yellow patches. Thornback rays, like other rays and skates have firm wing-like pectoral fins to help them glide through the water.

Rays are related to sharks and share many of the same characteristics such as having a body made out of cartilage, rough skin made from dermal denticles (or ‘skin teeth’) to give them an aerodynamic advantage in the water, and gill slits to breathe.

Rays have small openings called spiracles above their eyes on top of their body which allows them to breathe if they are sitting on the floor.
