 Spirula spirula
Spirula spirula is a small, muscular species (45 mm ML) found in mesopelagic waters of the tropical open ocean.
Spirula carries an unusual internal shell that is calcareous and has the shape of a horn coiled in a single plane without the coils touching one another (open planispiral).
Clarke (1969) found that Spirula occurs at depths between 550 and 1000 m during the day (peak distribution is at 600-700 m) and at night migrates into the upper 100-300 m (peak at 200-300 m).

Spirula are a genus of cuttlefishes or cephalopods comprising only three known species, so named for their very delicate shell being rolled into a spiral form.
The shells are very numerous on the shores of New Zealand, but the animal forming them is extremely rare, being seldom found except in it’s fragmentary state.
Live specimens of Spirula take on a vertical position, head downwards, when at rest.
