So while scientists are not sure why the male argonaut octopus detaches its penis during sex there must be a very good reason for it. When mating, male blanket and argonaut octopi will detach their specialised arms: a tentacle-like copulatory organ called a hectocotylus and give it to the female to fertilize her eggs.

This species of octopus, like other octopi, uses one of their tentacles to deliver the sperm inside the female – a much more intimate process than many other invertebrates. The paper nautilus or Argonaut is usually found near the surface of tropical and subtropical seas. Not voted quite as disgusting is the Hooded seal.
