Beautiful photos of a Bobtail Squid. These guys are more similar to cuttlefish than true squid, but without a cuttlebone. I’m not sure which species this is. They have a symbiotic relationship with bioluminscent bacteria, which don’t just make them beautiful but also hide them from predators; in return for sustenance, they react to light shone on the squid from above by producing a matching amount of light, making them difficult to spot from below. I’m not sure if they also have chromatophores like cuttlefish and some other cephalopods. Oh, and just to make them even cuter: they’re tiny. These ones are only about five centimetres long.
These photos were taken by wildlife photographer Todd Bretl, and originally published online by (American) ABC News. (Word of warning: his web site’s front page is mostly pictures of sharks, so don’t look if you’re phobic!)
