Pygmy squid
Idiosepius sp.
Family Idiosepiidae
updated Aug 10
Where seen? This tiny squid is commonly seen on many of our shores, among seagrasses and near reefs and rubble. Often dismissed as bits of floating rubbish, this small, well camouflaged animal is usually seen hunting alone.

Features: 1-2cm. The Family Idiosepiidae comprises only one genus Idiosepius that have a special glue gland on the upper body. A pygmy squid may use this gland to glue itself to the underside of seagrasses and seaweeds. Like other squids, it can change colours rapidly, check out Andy's awesome video clip.

Sometimes mistaken for a juvenile squid, this squid doesn't get very large.

What does it eat?
Tiny shrimps and crabs are its main prey.
