Did you know?
When threatened, the grey reef shark puts on an impressive intimidation display before attacking: arched back, lowered pectoral fins, and an exaggerated zigzag swim. It often gathers in groups near reef drop-offs during the day before hunting alone at night.
What defines this group — Sharks & Rays
The cartilaginous fish: not a single bone in the body, a skeleton made entirely of cartilage.
- A cartilage skeleton, lighter and more flexible than bone.
- No gill cover: five to seven gill slits open on the sides or underneath.
- Pores on the snout — the ampullae of Lorenzini — pick up the electric field of prey.
