Extreme plasticity in life-history strategy allows a migratory predator (jumbo squid) to cope with a changing climate.
Dosidicus gigas (jumbo or Humboldt squid) is a semelparous, major predator of the eastern Pacific that is ecologically and commercially important. In the Gulf of California, these animals mature atExpand

Brooding and sperm storage by the deep-sea squid Bathyteuthis berryi (Cephalopoda: Decapodiformes)
Squids of the family Bathyteuthidae have generally been infrequently encountered in their deep-sea habitat. Remotely operated vehicles were used to observe seven individuals in situ in the MontereyExpand

Spermatophore implantation in Rossia moelleri Steenstrup, 1856 (Sepiolidae; Cephalopoda)
The small sepiolid cephalopod Rossia moelleri Steenstrup, 1856 transfers sperm by implantation of spermatangia into female tissue. Although this is a common sperm transfer and storage strategy inExpand

Getting Under the Skin: Autonomous Implantation of Squid Spermatophores
Squid spermatophores are complex structures that store sperm and, when transferred to the female, evert into sper matangia. Some deep-sea squid implant spermatangia into unmodified tissue of theExpand
