Temperate Australasia


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.


Max Size: 5 cm

Sea Temperature Range: 17.7-22.9°C

Depth: 0-20m

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Data Deficient

Occurrence: Rare (0.8% 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: Several (9 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
