So I live in DC and I went to the National Zoo on a day off. They have a really old male cuttlefish - 20 months old, which is a Methuselah of a cuttlefish - and he sired offspring, three of which apparently survived, a male and two females. They did not know this until the male impregnated his sisters. No good can come of this for the cuttlefish (it's like cephalopodian Deliverance). At the same time, I am almost morbidly curious to see what kind of deformities come from this and what it can tell us about cephalopod genetics in general, since presumably octopuses, cuttlefish, and squid share a massive amount of genes.
