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
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

Hello! Nov-18-2019 This last year I went to Seaquest and fell even more in love with the Octopus when I was able to interact with it. We have an Aquarium about 100 miles away in Spokane, and they also have an octopus, but I recently learned they aren't able to interact the same way as the other aquarium. that's fine by me as I understand. Still. I would love to take a trip over to Blue zoo and see what they have. I want to learn everything about […]
Callistoctopus macropus suitable for home...
by firstname.lastname@example.org (Benjie) on November 18, 2019 at 6:54 pm
Hi there, our local fish store today told us they were offered an octopus labeled as "Callistoctopus macropus". Nothing of this animal is known, size, origin etc... Some research on Callistoctopus made us a bit sceptic: - night-active? - difficult to feed? - can get really huge? So, would you advise that we should stay in touch and get more information, or should we abandon the idea? ... that said, I was unable tu run a search in the forums ... where has the "search" button gone??? thanks for […]
Tropical octopus species for mid-sized tank
by email@example.com (Vindicus) on November 18, 2019 at 2:50 am
Hi all, Recently picked up a used tank from work that would suit itself well to being escape-proofed and I've been considering trying an octo at home. The tank is approximately 280 gallons and measures 72"x30"x30" (182x76x76cm). I would prefer a mid-sized species that I can interact with, as I used to be able to play with a GPO at my old job and I miss it. However, I'd rather not run a chiller on this tank for a number of reasons, foremost among them the fact that I'm setting up a large reef […]
