Twotone Pygmy Squid

Found singly or in squads, around mangroves and seagrass beds, over shallow, coastal waters and lagoons.
They feed nocturnally crustaceans.

Some of the smallest squids, they can change colour when predators come near.
These squid have a glue gland on their backs so they can cover themselves in sand for camouflage. There is also a light organ in their bellies, that hosts bioluminescnt bacteria which produces the iridescent colours.
