However, they are considered gonochoric like other members of the Cephalopoda class, which means they die shortly after mating and breeding. The giant squid’s genome includes 33,406 protein-encoding genes splayed across 2.7 billion DNA bases, compared to our 20,000 or so genes in a 3.2 billion base genome. REFERENCES: 1.
