Post-spawning egg care by a squid
Brad A. Seibel1,2, Bruce H. Robison1 and Steven H. D. Haddock1
Gonatus onyx is one of the most abundant cephalopods in the Pacific and Atlantic Oceans1 and is an important prey species for a variety of vertebrate predators2, 3, but a full understanding of its life history has been hampered because spawning occurs at great depths4, 5, where observation is difficult. Here we describe post-spawning egg care, or brooding, in this deep-sea squid. Our finding is unexpected because this behaviour differs from the reproductive habits of all other known squid species.
