Octopus bimaculoides: Arms and Suckers
Octopuses are perhaps most easily recognized by their eight appendages. The arms are strong muscular hydrostats, each covered with hundreds of suckers that allow octopuses to exert powerful suction forces. The flexibility and strength of octopus arms is a unique morphological innovation in the animal kingdom. The O. bimaculoides genome and transcriptome is reported by Albertin and Simakov et al.
