Hammer Octopus
Octopus australis
Octopus australis (commonly the hammer octopus or sometimes the southern octopus) is a species of octopus. It gets the common name hammer octopus from a modified arm possessed by males and used in reproduction. It was first described by William Evans Hoyle in 1885, based on a specimen found in Port Jackson in New South Wales.
