A.B.C. Octopus koellikeri = Tremoctopus violaceus (common blanket octopus)
The common blanket octopus or violet blanket octopus (Tremoctopus violaceus) is a large octopus of the family Tremoctopodidae found worldwide in the epipelagic zone of warm seas. The degree of sexual dimorphism in this species is very high, with females growing up to two meters in length, whereas males grow to about 2.4 cm. The first live specimen of a male was not seen until 2002 off the Great Barrier Reef. Individual weights of males and females differ by a factor of about 10,000 and potentially more.
