How fast can an octopus move?
25 miles per hour
Common octopus Unlike the other streamlined ocean animals on this list, octopuses don’t scream “speedy” at first glance.

How do octopuses envenomate?
From what I can find, it seems that octopus venom is produced in their salivary glands and is then secreted into the buccal mass, which is the muscular structure surrounding the beak (essentially the octopus’ mouth). Envenomation then occurs when the octopus bites its prey and the saliva, containing the venom, enters the bite wound.
Where do octopuses live?
Octopuses live in oceans all over the world. Most are pelagic, meaning they live near the water’s surface in shells, reefs and crevices. Some species live on the floor of the ocean, making their homes out of caves.
