Friday Squid Blogging: The Hawaiian Bobtail Squid Genome

The Hawaiian Bobtail Squid’s genome is half again the size of a human’s.

Other facts:

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.

Friday Squid Blogging: Multiple Organisms Co-Evolving in a Single Squid

Interesting research on the genomic evolution of the Hawaiian bobtail squid: “These analyses represent the first genomic insights into the evolution of multiple symbiotic organs within a single animal host.”

From a news article:

Now, Foster and an international team of researchers have mapped the genome of a Hawaiian bobtail squid, creating a new tool to explore these questions. By parsing the squid’s genome, the team has already discovered that the evolution of its light organ followed a completely different pathway than that of a second symbiotic organ, which supports reproduction.

Friday Squid Blogging: Squid-Focused Menus in Croatia

This is almost over:

From 1 December 2018—6 January 2019, Days of Adriatic squid will take place at restaurants all over north-west Istria. Restaurants will be offering affordable full-course menus based on Adriatic squid, combined with quality local olive oil and fine wines.
