Why does an octapus have tentacles?

User Avatar
Well, the octopus had ink glands like the squid, and if it had fins then not only would it look ridiculous, they couldn't get away from predators. Also, on a octopuses tentacles, there are suction cups. They can't get them on fins, and they work as hands. I think octopuses and tenctacles get along, not fins. Don't you?

Is an octopus a vertebrate?

User Avatar
No. Because an octopus has no internal skeleton or spine/back bone, it is classified as an invertebrate. More information: The octopus is a mollusk, a grouping with many various characteristics. Squid are also mollusks. Both fit into the definition of invertebrates because they do not have an internal skeleton with a spine. For more information about mollusks, see the related links with this question.
Asked in Octopus

What is the average height of a octopus?

User Avatar
Sea creatures are usually measured by length, rather than by height, since they are generally not found in a standing position, unlike land animals. On average, an octopus is several feet in length if you count the tentacles. The central body mass, other than the tentacles, is typically about ten inches in diameter.
