octopus : any of a genus (Octopus) of cephalopod mollusks that have eight muscular arms equipped with two rows of suckers; broadly : any octopod excepting the paper nautilus — Webster

octopuses or octopi (Merriam-Webster)
OneLook, Free Dictionary, Wiktionary, Urban Dictionary


Roget’s II (Thesaurus.com), Merriam-Webster Thesaurus, Visuwords


Octopus is a soft-bodied, eight-armed mollusc of the order Octopoda. Around 300 species are recognized and the order is grouped within the class Cephalopoda with squids, cuttlefish and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the centre point of the arms (which are sometimes mistakenly called “tentacles”). The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight arms behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviorally diverse of all invertebrates. — Wikipedia

  • Theon - O. briareus Back with a new baby!
    by invalid@example.com (sedna) on August 17, 2019 at 7:57 pm

    I got this new little one two weeks ago from KP Aquatics. I haven’t had one since the last one passed in December, and now that we’re safely two weeks into acclimation, I’m ready to start a journal! I’d say it’s a small briareus, but sometimes I’ve thought that and they turn out to be a joubini. I just got those FluvalSmart lights and love the ability to control dawn & dusk! I’ve been keeping it set to 1% red light over night, starting at 7pm […]

    by invalid@example.com (Tomh) on August 17, 2019 at 3:22 am

    Hi recently got a juvenile twin spot about 2 weeks ago. His mantle is about 1 1/2 -2 inches. I had him in a critter container until he ate frozen then released him to tank. His second in tank he is exhibiting some behavior I have never seen!! I have a rock partially buried in sand. He dug a hole under rock and seems to be making a den under it? I had one before and he never done this? Is this normal for them? Thanks

    on August 15, 2019 at 12:09 pm

    Fossilised flies that lived 54 million years ago have revealed a surprising twist to the tale of how insects' eyes evolved. These craneflies, unveiled in Nature today, show that insect eyes trap light the same way as human eyes, using the pigment melanin—yet another example of evolution finding similar solutions to similar problems.

  • Decoding the complex life of a simple parasite
    on July 30, 2019 at 1:12 pm

    Dicyemids, microscopic parasites comprising 30 cells, are in-between creatures. With their basic three-part body plan, they are more complex than single-celled protozoans but considerably less complex than multicellular metazoans—the animals of the kingdom Animalia. Yet the simple makeup of these so-called mesozoans does not translate to a simple life.

    Animals have an intimate and important connection with the microbial populations (microbiomes) that live inside their bodies. This holds for the behaviorally sophisticated cuttlefish, whose microbiome, it turns out, contains only two different kinds of bacteria.

    Superglue is incredibly useful—right until you end up attached to your craft project. But a new adhesive invented by University of Pennsylvania scientists is just as strong as standard superglue, and far more forgiving. The adhesive, based on snail slime, can be unattached and reattached over and over without losing its strength, and may save manufacturers from costly mistakes.
