Spirulidae: Spirula spirula  (Linnaeus, 1758) ('common ramshorn-squid')  

Synonym(s): spirula Linnaeus, 1758.

Figure a: 12 mm, Falmouth, TAS (E), coll. S. Grove.

Typical shell-length 23 mm. Living animal is a deep-water pelagic squid. Once dead, the animal's chambered, gas-filled shell floats and may drift a long distance before beaching. Lives in offshore waters in midwater, undertaking diel migrations from 1000 m depth by day to 100 m by night.  Native. Occurs all around Australia (QLD, NSW, TAS, VIC, SA, WA and NT); also widespread in warmer oceanic waters worldwide.  In Tasmanian waters the beached shells of this species are mostly recorded from the E coast, where it can occasionally be common.
