  1. Squid, octopus and cuttlefish have scrambled-up genomes that may help explain how these cephalopods evolved the most complicated nervous systems of any invertebrate. New genetic sequencing reveals that these animals' genes are mixed up, arranged in strange orders not seen in other, non-cephalopod species.

    Do squids have a complex brain?
    It seems that the blueprint for complex brain development remains the same, despite 500 million years of divergent evolution. Scientists who watched nerve cells connect inside the eyes of growing squid have uncovered a remarkable secret — the cephalopods’ brains independently evolved to develop in the same way ours do.

    Is a squid a cephalopod?
    This squishy, walnut-sized creature is a cephalopod (a group that includes octopuses, squids and cuttlefish), the only invertebrate group that has evolved nervous systems and behaviors as complex as what we see in mammals and birds.

    Why do octopus and squid have a brain-boggling genome?
    'Mind-boggling' scrambled genome found in octopus and squid. It could explain their smarts. Just as in vertebrates, the researchers saw the squids’ progenitor cells arrange themselves into a structure called a pseudostratified epithelium — a long, densely packed structure that forms as a crucial step in the growth of large, complex tissue.

    How did squid evolve?
    They describe how the animals evolved using a family of chemotactile receptors within their arms and offer a glimpse into how such functional changes likely took place as adaptations to environment over deep evolutionary time. Squid are ambush predators that strike and capture unsuspecting prey with their eight arms and two long tentacles.

    Can squid be a model for Neuroscience?
    The Atlantic longfin inshore squid, Doryteuthis pealeii, has been studied for nearly a century by scientists as a model system for neuroscience investigations. Credit: Elaine Bearer Squid, octopus, and cuttlefish—even to scientists who study them—are wonderfully weird creatures.

    Could editing squid genomes help us understand nervous systems?
    Squid's giant nerve fibers have been essential to research for decades. Now breakthroughs in editing squid genomes could lead to a more complete understanding of nervous systems in general. “We’ve got tuuuuuubes!” fisherman Matt Rissell shouts as he leans over the gunwale of the Skipjack to check his line.
