Unable to defend themselves, octopuses often fall prey to predators. [76] This makes most octopuses effectively semelparous . The larger Pacific striped octopus (LPSO) is an exception, as it can reproduce repeatedly over a life of around two years.
With both smarts and dexterity, in addition to arms that can think for themselves, octopuses can do fascinating things. Just like the octopus did in the video when it forcibly tore off the pacifier.
Opisthoteuthidae are a group of octopuses characterized by a web of skin in between their arms. They broad U-shaped shell that support muscles for a pair of small fins on the mantle, these fins are far less developed than other families in Cirrina and essentially only act as stabilizers when the animal swims (using a medusoid motion of the arms and webbing).

Two distinct behaviors have been observed in inking cephalopods. The first is the release of large amounts of ink into the water by the cephalopod in order to create a dark, diffuse cloud (much like a smoke screen) that can obscure the predator's view, allowing the cephalopod to make a rapid retreat by jetting away.
The more scientists study octopuses, the more we learn how fascinating these creatures really are. Octopuses are incredibly intelligent, displaying all kinds of amazing behavior like completing ...
Octopuses taste by touching objects with their tentacles. Here's a sampling of the coolest animal discoveries from 2020. 22 discoveries this year changed our understanding of how animals ...
The major neurotoxin component of the blue-ringed octopus is a compound originally known as "maculotoxin"; in 1978, this maculotoxin was found to be tetrodotoxin, [17] a neurotoxin also found in pufferfish, rough-skinned newts, and some poison dart frogs; the blue-ringed octopus is the first reported instance in which tetrodotoxin is used as a ...
