Octopus oliveri explained

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. Females will take longer to mate, the larger their body size.^[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.^[4]
