Vampire squid stranger, even, than previously thought.

Science Daily goes deeper into the singular (and kinda sexy) oddness of the vampire squid:

At ocean depths from 500 to 3,000 meters, they don’t swim so much as float, and they get by with little oxygen while consuming a low-calorie diet of zooplankton and detritus. Now, researchers reporting in the Cell Press journal Current Biology on April 20 have found that vampire squid differ from all other living coleoid cephalopods in their reproductive strategy as well.

“Their slow mode of life seems insufficient to support one big reproductive event, unlike other coleoid cephalopods,” says Henk-Jan Hoving, who is working for the Cluster of Excellence “Future Ocean” at the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany. “Perhaps it is therefore that vampire squid return to a gonadal resting phase after spawning, and presumably start accumulating energy for a new reproductive cycle.”

In other words, they make a little whoopee, then take a little break, then make a little more, then take another break. Most other squid species save up for one big outing… which just sounds like a recipe for heartbreak to me.
