The Indonesian mimic octopus has the boldest defense strategy of any of its cephalopod cousins, and now scientists know how that strategy evolved. Rather than blending into the scenery, the octopus mimics the swimming behavior and shape of a variety of toxic sea creatures, like flatfish and sea snakes, and displays bold color patterns that shock predators. Scientists have reconstructed the family tree and unique evolution of the Indonesian mimic octopus,
Thaumoctopus mimicus, using DNA sequences from 35 of its relatives.
