• Squid and octopus genome studies reveal how cephalopods' unique traits evolved

    23 days ago - By ScienceDaily

    Squid, octopus, and cuttlefish - even to scientists who study them - are wonderfully weird creatures. Known as the soft-bodied or coleoid cephalopods, they have the largest nervous system of any invertebrate, complex behaviors such as instantaneous camouflage, arms studded with dexterous suckers, and other evolutionarily unique traits. Now, scientists have dug into the cephalopod genome to understand how these unusual animals came to be. Along the way, they discovered cephalopod genomes are as weird as the animals are. Scientists from the Marine Biological Laboratory in Woods Hole, the...
