Once they can hold a shotgun, we’re doomed. Or the octopuses are.

lobster-deformity

One annoying thing is that the news report keeps saying it has multiple claws. No, it does not. It has two big chelipeds, the correct number, and it has a number of walking claws or pereiopods that look about right. The left cheliped is weird: I can’t tell for sure, but it either has mirror-image duplication of the propodus and dactylus, or multiple duplications of the dactylus. The latter would be interesting; that would suggest a failure of the proximal-distal patterning information in the claw.

Someone more knowledgeable in the fine-grained morphology of lobster claws ought to do a labeling of the digit identities for us.
