What are the peculiarities of the octopus s senses?

Characteristics of octopuses: octopus body is short oval, sac-shaped, finless; The head and body are not clearly divided, and the octopus has a large compound eye and 8 retractable wrists on the head about centimeters. Each wrist has two rows of fleshy suction cups, with the wrists of short clams about 12 cm long, long clam about cm long, and real clams about cm long.

Octopus is a temperate mollusk, living underwater, adapting to the water temperature can not be lower than 7, the proportion of seawater is the most suitable, and the environment with low salinity will die. The bottom of the sea area is preferably a gravel area, and the water temperature is above 12 years to spawn.

How octopuses reproduce.

The breeding time of octopuses in the ocean is generally concentrated in spring and autumn. Octopuses like to spawn in the snail shell, so they can use a rope to sink into the bottom of the sea through the red snail shell, extract and catch it on time, and often burrow in the sediment of the deeper sea in autumn and winter.

During the breeding season, female octopuses lay eggs, about centimeters long, with a total of more than 100,000, under rocks or in holes. During incubation, the female guards the eggs, cleans them with a suction cup, and agitates the eggs with water. Female octopuses need their larvae to hatch after 4-8 weeks after a single spawning.

Juvenile octopuses are small and adult-like, and after hatching, they drift with plankton for several weeks before sinking to the bottom to hide.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately

Hello, glad to answer for you, 1 octopus is a mollusk and has no bones (all bones are degenerate). 2. The octopus is a cephalopod with a total of 8 brachiopods that grow on the head. 3 Octopuses have the highest intelligence of all invertebrates.

4. Octopus** contains highly developed pigment-containing cells, which can change body color very quickly. The body color of the octopus can be used as a protective color, and it is said that it can also reflect the mood of the octopus. 5 The octopus relies on sucking water into the mantle and expelling the water through a short funnel-shaped tube to breathe outside the body.

When an octopus is frightened, it squirts water from its body tubes and quickly moves in the opposite direction by means of a hydrodynamic jet to avoid danger. 6When the octopus encounters danger, it spews out an ink-like substance that acts as a smoke screen to avoid danger.

Octopus (scientific name: octopodidae), octopodidae, octopidae of the order Octopodidae. The octopus is short oval, sac-shaped, finless, temperate mollusk, lives underwater, can feed on large animal plankton and grows, inhabits caves or crevices on the rocky seabed, and likes to hide.

It is widely distributed in tropical and temperate seas of the world's oceans.

The main characteristics of the octopus are:

1.It has an amazing ability to change color.

1) The octopus can change its color at any time and become in harmony with the surrounding environment, even if the octopus is injured, it still has the ability to change color.

2) Under the ** of the octopus, there are many pigment cells hidden, and there are different colored liquids inside, and there are several dilators in each pigment cell, which can make the pigment cells expand or shrink.

3) When the octopus is panicking, excited and other emotional changes, its ** will change color, at the same time, the command system that controls the change of octopus body color is mainly its eyes and cerebral medulla, if there is a problem with one side of the eye and cerebral medulla, then this side is fixed to a color, and the other side can still change color.

2.Superb escape skills.

Because the octopus can store water in the mantle cavity and can live on oxygen dissolved in the water, it can still live for a few days even if it is away from the seawater.

3.Featuring eight sensitively sensitive tentacles.

1) There are about 300 suction cups on each tentacle, and each suction cup has a pull of 100 grams, so whoever gets entangled in the tentacles of an octopus will have a hard time getting out.

2) The tentacles of the octopus are the same as the human hand, with a high degree of sensitivity, which can be used to detect the movement of the outside world, when the octopus is resting, there are generally one or two tentacles on duty, and the tentacles on duty are constantly moving around, highly vigilant.

1- Octopuses belong to cephalopod steel mollusks. 2- The octopus has eight legs, all of which grow on the head, called brachiopods. 3- Because it is a mollusk, there are no bones in the body. 4- The octopus is a body that can change color and even change the shape of its own body.

The warts on the surface of the octopus's body are densely populated, and the pigment cells are distributed throughout the body. It can change body color and body length according to its surroundings, and exhibits good mimicry in rocks and seaweed. Octopuses use suction cups to crawl along the bottom of the sea, but when frightened, they spew water from their body tubes, rapidly moving in the opposite direction.

When encountering danger, it will spray an ink-like substance that acts as a smoke screen. Some species produce substances that can paralyze the attacker's sensory organs. <
