The Hawaiian Bobtail Squid’s genome is half again the size of a human’s.
The Hawaiian bobtail squid has two different symbiotic organs, and researchers were able to show that each of these took different paths in their evolution. This particular species of squid has a light organ that harbors a light-producing, or bioluminescent, bacterium that enables the squid to cloak itself from predators. At some point in the past, a major “duplication event” occurred that led to repeat copies of genes that normally exist in the eye. These genes allowed the squid to manipulate the light generated by the bacteria.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
