Octopuses occasionally stroll around on two arms, UC Berkeley biologists report: "When walking, these octopuses use the outer halves of their two back arms like tank treads, alternately laying down a sucker edge and rolling it along the ground. In Indonesia, for example, the coconut octopus looks like a coconut tiptoeing along the ocean bottom, six of its arms wrapped tightly around its body."

There have been observations of some fishes using their side fins as limbs to wriggle. This was especially required in swampy areas where there was a lot of muck to get through. Swamps are thought to be the testbed for limb evolution, and thereby for the first tetrapods who came out of water to become the first land vertebrates. Coelacanth is regarded to be a living fossil to play a vital role in such a development. Post a Comment
