Overview
Found singly or in squads, during the day in warm shallow coastal waters, hovering close to estuaries, rock reefs, and seaweed reefs, moving to deeper waters at night hunting for food.
They feed nocturnally on crustaceans, fish, and molluscs.
These squid are sometimes mistaken for cuttlefish due to the large fin that surrounds their mantle.
Commonly seen at night and can be inquisitive of divers, however if approached they can swim backwards at great speed producing a jet of water from the funnel in the front. Their fins are used for turning.
This species is known for its elaborate courtship displays and size sorted schooling behaviour.
In some pictures can be seen the nursery of squid eggs hanging on lines like washing drying! All in sausage shaped bundles, when the squid hatch they will be as tiny as a grain of rice.
