How can the soft bodies of coleoid cephalopods so aptly hide in their environment? Why must they? What cells and specialized organs make such crypsis possible for one of the older evolutionary ...

During the pandemic, researcher Daniela Rößler couldn't go out, so she started looking around her for her next research ...

Ammonites were shelled cephalopods that died out about 66 million years ago. Fossils of them are found all around the world, sometimes in very large concentrations. The often tightly wound shells of ...

The many chambers of their shells likely helped these cephalopods glide through the planet’s warm, shallow seas. A thin, tubelike structure called a siphuncle pumped air through the interior ...

Science Giant creatures evolve beneath the ocean's surface. Their discovery changes our perception of underwater life. At depths of over 8,200 feet (2,500 meters), scientists have uncovered a ...

Mating happens at arm’s length for the four species of these cephalopods. The tiny male detaches its hectocotylus—a modified arm that holds its sperm—and gives it to the female, who keeps it ...

Drawing on over 300 scientific studies, we have evaluated the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid ...

Onlookers glimpsed an “incredible sighting” in a California harbor, a business said. About 25 octopuses surfaced over the ...

Scientists believe they have only scratched the surface of the way animals are being forced to adapt to plastic, and the ...

Sleep is one of the most mysterious, yet ubiquitous components of our biology. It has been described in all major groups of ...

We are also studying the evolutionary origins of the hair cells of the inner ear by studying the development of similar sensory cells in cephalopods (squid) and urochordates (sea squirts).
