The octopus is an invertebrate animal, which means it has no single bones in their body. It also lies in a sub-species of mollusks called the cephalopods which means from “head to foot” and is used as the name because of an octopus because “feet” are attached to its head. It can only be found in salty water mostly on a beach or sea, but they live in all the oceans too. The octopuses which live in warm waters tend to be small then who live in cold water. The ones that live in colder waters are much larger compared to the octopus who lives in warm water. It only consists of a life span of 1 to 2 years and not more than that. There are about 300 known species of octopus in the worldwide.
It’s body is usually looks like a bag. It also has a bulbous head, large eyes, and consists of eight arms in its body. It’s arms have suckers also known as tentacles. The arms consist of many nerves which allow it to grab and taste things.
It has super-powerful eyesight but poor hearing power something like between 400Hz and 1000Hz. Octopus got three hearts and it’s blood is light blue in color. It is considered as the most intelligent animal among all the invertebrates in the world.
Octopus has a beak around its mouth. It can grow to about 4.3 feet i.e. 1.3 meters long in length and weigh up to 22 pounds i.e. 10 kilograms. Although the average octopus is a little smaller. Similarly, the Giant Pacific Octopus lives in the coastal waters off of British Columbia and is known as the largest octopus in the world. The largest one weighed 600 pounds and its tentacles spanned 33 feet long.
Likewise, when a female octopus lays eggs, it takes about a month for the eggs to be mature and to hatch. The female guards her babies the entire time. Because she is not hunting during this time and it is very common for the female to become extremely weak and die due to starvation around the time of her young are hatching.
