Octopus oliveri (Berry, 1914)

DIAGNOSIS.—Animal small to medium-sized (“dorsal length of body” 27–30 mm (Berry, 1914b:136)). Mantle broad (MWI 103–137), pyriform, widest posteriorly; neck weakly constricted; head short, narrower than mantle (HWI 77–89); eyes elevated, with small, puckered openings. Arms short (ALI about 75), stout, tapering abruptly near tips, arm formula II = III > I = IV; proximal 4 suckers on each arm uniserial, suckers biserial distally. Web thick, shallow. Dorsal surface of mantle and head with numerous conical papillae; eye surrounded by circumocular ring of 5 to 6 low, individual papillae, supraocular papillae absent; ventral surface smooth. Color dark slate dorsally, lighter ventrally. Inner surface of suckers light brown to cream.

ORIGINAL DESCRIPTION.—Berry, 1914b:136, as Polypus oliveri.

TYPE LOCALITY.—Sunday Island, Kermadec Islands (intertidal among rocks).

TYPE.—Holotype: USNM 816455, female, 30 mm ML, SSB no. 405.

DISTRIBUTION.—In addition to the type locality, Okutani etal. (1987) attributed a specimen from Ishigaki Island, Okinawa, to this species.

Octopus oliveri

provided by wikipedia EN

Octopus oliveri, is a species of octopus found in the western Pacific Ocean off the coast of Japan, Hawaii, and Kermadec Island, in reefs and boulder coasts.[1][2]

It is a small species, roughly 70-260mm in length.[2] Females will take longer to mate, the larger their body size.[2][3] Afterwards, ~5000 eggs will hatch in about five weeks after being laid, and the male/female ratio seems unaffected by temperature. These eggs are laid in strings attached to a hard substrate.[2][4]
