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: About 1cm. Body long
cylindrical, with tiny circular fins at the rear end. It is often
seen floating about with its longer tentacles extended beyond the
shorter arms, with a slight curl at the tips of the tentacles. It
has been seen catching shrimps that are as big as the squid.
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
where it lurks in wait for prey. Like other squids, it can change
colours rapidly, check out Andy's awesome video
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.
It is said that
that to catch shrimps, it sneaks up on a shrimp and immobilises the
prey by biting through the nerve cord.
