The vampire squid

The vampire squid does not ink.The tips of its tentacles emit a cloud of bioluminescent sticky mucus that glows for up to 10 minutes, plenty of time for the squid to escape a predator.

Vampire squid are cephalopods that are about the shape, size, and color of a football. The name “vampire” was given to these little squid because of the dark blood-red coloration, eye color (sometimes blue in different lighting), and what looked like spines on the tentacles.

These gave rise to the false idea that it sucked blood out of its victims. In fact, these squid float peacefully in their deep, dark, oxygen-deprived habitat, waiting for food to come to it— a different behavior than that of other squid and octopus species.

The vampire squid can turn itself "inside out" to avoid predators.
