Another cute (almost) photo and this is the banded piglet squid (Helicocranchia pferreri). Its name comes from its rotund shape and normally it's found more than 320 feet or 100 metres below the surface of the ocean.
Measuring just 3.9cm in length, this squid species has a singular light producing organ (photophore) to help it navigate the depths.
Because of its deep water habitat little is known of its behaviour but it is known to be a sluggish swimmer with ammonium ions in its body fluid to help keep it bouyant and in this photo it's swimming upside down. Look at the frilly frippy of its little back fins, sweet.
The image was taken from a remotely operated vehicle (ROV) in the Gulf of Guinea near oil pumping equipment at a depth of 1015 metres.
They like tropical and subtropical oceans also the north temperate waters of the Atlantic Ocean with the smaller squid staying higher in the water table and descending into deeper water as they get larger and older.
