Global proliferation of cephalopods
Human activities have substantially changed the world’s oceans in recent decades, altering marine food webs, habitats and biogeochemical processes. Cephalopods (squid, cuttlefish and octopuses) have a unique set of biological traits, including rapid growth, short lifespans and strong life-history pl...

Human activities have substantially changed the world’s oceans in recent decades, altering marine food webs, habitats and biogeochemical processes.
