Stressed out? Take a minute to stop and appreciate the beauty in my recovering squid.

This juvenile glass squid (Bathothauma lyromma) haunts the waters with stalked, bulbous eyes and two short arms. Like many glass squids, members of this species contain light-emitting organs on their lower surfaces, which are used to fool predators and obscure the silhouette of their eyes.

Octopus Squid (Octopoteuthis deletron)-
O. deletron, is a deep sea dwelling cephalopod and is under multiple scientific studies due to its handful of strange traits.
It is unique to the O. deletron to be (one of the?) only squid to have only eight arms and no tentacles. Babies (bottom left) lose their two tentacles as they mature. Light flashing photophores at the tips of the arms attract prey, and possibly mates. O. deletron is able to drop parts of its arms at will. The sharp “teeth” on its arms hook onto predators and prey. If needed, the squid can detach any arm at any length (unlike an octopus that drops the entire tentacle). Like a lizard tail, the arms grow back.
Also unusual among squid, the O. deletron sports a large penis. In the photos, o. deletron displays small white dots on near its mantle. These are sperm packets deposited by passing males. Since they are solitary and live in the deep sea, finding a mate is difficult. Whenever a male o. deletron meets another member of its species, it will deposit its sperm packets regardless of the gender of its companion.

Cannibalism Amongst Deep Sea Squid
Cannibalism is not so unusual in the deep sea, especially for squid, but until recently the diet of Gonatus squid was largely unknown. By using ROVs to make observations of these squid in their natural habitat, scientists now know a great deal more about their feeding behavior.
A recent paper by Henk-Jan Hoving and Bruce Robison reveals that the diet of the two similar Gonatus squid species—Gonatus onyx (bttm image) and Gonatus berryi (top) — have a higher than expected incidence of cannibalism.
Hoving is a former MBARI postdoctoral fellow and is now with the Helmholtz Center for Ocean Research Kiel, Germany; Robison is an MBARI senior scientist and midwater ecologist.
