Genus of octopuses
Paroctopus is a small genus of octopuses from the family Octopodidae.
"Paroctopus" are small-bodied; short mantled, pouch like octopuses with short, stocky arms which are 2 or 3 times the length of the mantle. The males have 1-3 enlarged suckers on each arm with their right third arm being hectocotylised and shorter than its opposite arm. There are stylets and these are non-mineralised. One to 3 enlarged suckers on all arms of males only. The ligula is of medium size with a short calamus. Their gills have 6‑8 lamellae per outer demibranch. "Paroctopus" lays small to medium-sized eggs which are on very short stalks and are attached singly in small clusters within the empty shells of gastropods and bivalves. They are uniformly coloured with little variation in pattern and they lack a patch and groove system. There is a faint frontal white spot complex. The integument lacks large primary papillae.
The species of Paroctopus are distributed in the northeastern Pacific Ocean off Mexico and the Gulf of California and in the western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico.
