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. Ref: https://en.wikipedia.org/wiki/Euprymna_berryi
