Same Genus
Distribution
Temperate Australasia
Description
Unlikely to be confused with other cephalopods, because of its distinctive black stripes down the body and its small rounded shape. The species is common on sand in estuaries and along the open coast. When disturbed, striped pyjama squid commence a spectacular display of colour and pattern changes. Females lay eggs in objects such as shells and tin cans and guard them until hatching occurs.

Conservation and Rarity
IUCN Status: Data Deficient
Occurrence: Rare (0.6% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Solitary (1 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
