Venomous Cephalopods

We were lucky enough to see and photograph our first flamboyant cuttlefish on our recent Philippines holiday.  We knew these critters were small, but I still wasn’t prepared for how small, about 5-7 cm.  Also I didn’t know they are poisonous, like the striped pyjama squid and the blue ring octopus. The flamboyant cuttlefish is one of the few venomous cephalopods.

Nelson Bay, Australia is the only other place where we’ve come across other venomous cephalopods while scuba diving.

The pyjama squid (technically a cuttlefish) is about the same size as the flamboyant cuttlefish, but a lot harder to find.  They tend to bury themselves in the sand with just their eyes poking out.
