Encyclopedia

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

  • New Antarctic deep-sea doco with cool squid...

    Hi folks... after a rather unbelievably long wait, the documentary I was part of in January 2017 is finally airing in the US. It will be on tomorrow evening (16 May) in the US, on Nat Geo Wild. Don't know exact time, sorry. But you can apparently also watch it here Channel Homepage . The title is a bit of a mystery... we weren't hunting the giant squid... but OK. Still encountered some stunning animals (cephs and others). I have not actually seen this version, but I hope those who watch it […]

  • Theon - O. briareus Back with a new baby!
    by invalid@example.com (sedna) on May 20, 2019 at 11:25 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 (Tintenfisch) on May 20, 2019 at 7:42 pm

    Soooooo while I wasn't looking, our resident Crafting Wizard @Heather Braid made a full-scale anatomically correct female giant squid, with internal organs and removable beak. We have many marine-education-related plans for her (the squid, but also Heather I suppose) but first she needs a name! We've put out a call for suggestions on Twitter, but would love to hear suggestions from the TONMO community as well, since we know you all to be brilliant, ceph-minded and--above all--punny! […]
