Macroctopus maorum
Maori octopus | Octopus maorum
Distribution
Temperate Australasia
Description
Dark red colour, smooth skin, long arms of unequal length and the head being separated from the body by a distinct constriction. For a long time this species was known as O. flindersi, but recent work indicates that Australian animals are the same as the New Zealand-named species O. maorum. This octopus is a major predator of rock lobsters and is caught incidentally in lobster pots in sufficient quantities to be commercially important in its own right in South Australia.

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (4.4% 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.
