Description

The blind shark is a small bottom shark (Brachaeluridae) from coastal waters of eastern Australia. The species grows to about 1.2 metres and has a stocky, brownish body with barbels and small eyes. Its name comes from the habit of closing its eyelids when caught, not from actual blindness. As a nocturnal bottom-dweller it lives among rocks and reef crevices of shallow coastal water and eats small invertebrates and small fish. It tolerates some time out of water. The fish is harmless to humans.
