1987. If the invertebrate structure has suckers along its entire length, it's called an arm; if it only has suckers at the tip, it's called a tentacle. Tentacles: Doctor Octopus' superhuman abilities derive from the four mentally-controlled, electronically-powered, telescoping, prehensile titanium-steel tentacles attached to a stainless steel harness encircling his body from lower chest to waist.

Where cephalopods are concerned, marine biologists are careful to distinguish between "arms" and "tentacles." In addition, tentacles generally come in pairs. The tentacles are the parts that contain most of the nervous system which aids in the octopus locomotion and other hunting and feeding strategies as well as for defense (Mazzolai et al, 2013). If you believe that eight are too many, here is a shocking piece of information for you: a 96-tentacled octopus has been captivated and displayed in a Japanese aquarium. In: W.B. Thousands of neurons are present within these systems which influence lots of different sophisticated behaviours unique to the octopus (Altobelli and cimini, 2007).The eyes are another interesting organ. The order Octopoda includes 289 species, according to the World Animal Foundation. The brain is part of the central nervous system and consists of a large amount of lobes including optical lobe and frontal lobe.

A study has determined that the octopus has two legs and six arms, often commonly referred to as "tentacles".

The octopus is essentially a mollusk that lacks a shell but has eight arms and three hearts. The term cephalopods, in other words, is used to indicate that these species have their limbs attached to their heads. One species of octopus however possesses a small internal calcareous shell produced by the mantle [WWW2]. Some cephalopods have tentacles as well as arms, but the octopus manages just fine with the eight arms it uses for practically everything: eating, moving, hunting, tasting and mating. Its complex brain and large nervous system make this organism possess the most advanced cognitive behaviours of all invertebrates. The octopus is classified among the cephalopods (together with the squid and cuttlefish) which is again a Latin term translated as ”headfeet”. Similar Illustrations See All. Out of all the Cephalopods, the octopus has displayed the highest cognitive prowess, or of any invertebrate for that matter, along with its highly developed eyes, make it worth focusing on [WWW1]. It is speculated that the extra tentacles are the result of an abnormality during the process of regeneration. If the invertebrate structure has suckers along its entire length, it's called an arm; if it only has suckers at the tip, it's called a tentacle. This process lasts for around 100 days and it is surely one of main reasons why octopuses are such magical creatures.Why do octopuses need so many arms?

Where cephalopods are concerned, marine biologists are careful to distinguish between "arms" and "tentacles." Each tentacle, approximately five inches in diameter, terminates in three single-jointed pincers.
