Post-spawning egg care by a squid
Brad A. Seibel1,2, Bruce H. Robison1 & 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.
