How many feet does an octopus have?

Most octopuses have eight long feet on their heads, so they are commonly called "octopus". Octopus is short oval, cystic and webless, and the boundary between head and body is not obvious. There are big compound eyes and eight retractable wrists on the head. Each wrist has two rows of fleshy suckers connected by membranes, and the wrist has two rows of sessile suckers, so it is called "octopus" and does not belong to fish.

Introduction of octopus

Octopus is a very common seafood in our life. Octopus has eight feet, its body is saccate and short round, and the boundary between head and body is not obvious. The head has a big compound eye and eight flexible wrists, and each wrist has two rows of fleshy suckers. Octopus is a kind of temperate mollusk, which is widely distributed in tropical and temperate waters all over the world and mainly inhabits caves on the rock bottom.

The average life span of octopus is about 3 years. They are soft marine creatures, and their specific life span will be affected by their growing environment. If octopuses live in a comfortable environment and are not caught, they can live for about 4 years, at most not more than 5 years.

If it is a cultured octopus, the life span will be shorter, generally within 3 years. Because the environment of artificial breeding can not completely simulate the marine environment and the food fed is not rich enough, their life span will also be shortened. In addition to the growing environment, the species of octopus will also affect the life span. Like a giant octopus, its life span will be shorter.

There are many kinds of octopus, and their bodies are different. According to statistics, there are about 600 kinds of octopus in the world. Different kinds of octopus have different body shapes in adulthood, such as some smaller octopus, such as arboreal octopus, which is about 5 cm long in adulthood.

There are also some large octopus, such as the Pacific octopus, whose tentacles are all spread out in adulthood, with a diameter of 7.8 meters. The weight of this octopus is also very high, reaching 100 kg. So how big octopus can grow depends on their species.
