Cephalopod limbs bear numerous suckers along their ventral surface as in octopus, squid and cuttlefish arms and in clusters at the ends of the tentacles (if present), as in squid and cuttlefish. [9] Each sucker is usually circular and bowl-like and has two distinct parts: an outer shallow cavity called an infundibulum and a central hollow ...
Octopuses offer many possibilities in biological research, including their ability to regenerate limbs, change the colour of their skin, behave intelligently with a distributed nervous system, and make use of 168 kinds of protocadherins (humans have 58), the proteins that guide the connections neurons make with each other.
Both octopuses and squids have mantles (referenced above) which function towards respiration and locomotion in the form of jetting. The composition of these mantles differs between the two families, however. In octopuses, the mantle is made up of three muscle types: longitudinal, radial, and circular.
Akkorokamui's nature as an octopus means that it is persistent and it is near impossible to escape its grasp without permission. [ citation needed ] Akkorokamui enjoys the sea and offerings which reflect this: fish, crab, mollusks, and the like are particular favorites of Akkorokamui, which give back that which it gave.

Giant Pacific octopuses are able to recognise individual humans [66] and common octopuses can recognise other octopus individuals for at least one day. [ 67 ] In a study on social learning, common octopuses (observers) were allowed to watch other octopuses (demonstrators) select one of two objects that differed only in colour.
Deer grow antlers anew each spring, often at the rate of an inch per day. Now, scientists want to take the cells that power deer antler growth and figure out how to give that same ability to humans.
Researchers usually use naturally occurring injuries and/or scars to identify individuals but this technique does not work for long term identification. An octopus is able to regenerate limbs and heal in a relatively short amount of time. Researchers can also use external tags to help track individuals but octopuses are able to remove external ...
