What does a starfish look like? What is Starfish? What does it look like?

There are many kinds, there are more than 50 kinds in our country, there are Roche sea pan cars like five-pointed stars, forming a protective color very similar to five-pointed stars, and the food of starfish is crustaceans.

Starfish is a phylum of echinoderms, with a body like a disk, with 5 long antennae like a five-pointed star, and a bread starfish that is raised like a hat, mostly bright red and dark blue.

Starfish have peculiar bodies and live in the calm waters of the intertidal zone and near shore. Most of them inhabit the lower layer of the coast or the shore with deep water, rose, orange, some will be dotted with purple insect patterns and trim on the pink background, the petrel with short and blue wrists, the cocktail starfish with thin claws and the lotus starfish with lotus leaves.

Starfish have bright body colors, also called star fish, and starfish are widely distributed. Starfish can change color depending on the environment, and can be found in oceans all over the world, and some have a red border in blue.

The body of the starfish is pentagonal, the body is flattened, and the symmetry of five radiations is mostly symmetrical, and the boundary between the body disc and the wrist is not obvious.

Starfish, sea cucumbers, and sea urchins are the same echinoderms. They usually have five wrists but also have four or six, some as many as 40 wrists, and can use tubular feet to capture prey and allow themselves to cling to rocky reefs, and large starfish have thousands of tubular legs. The starfish's mouth is in the middle of its underside and is in direct contact with the surface of objects that the starfish crawls on.

Starfish vary in size, from as small as 2 5 centimeters to as large as 90 centimeters, and their body color is also different, almost all of them are different, and the most common colors are orange, red, purple, yellow, and cyan.

A sea animal covered in echinoderms——— starfish has a peculiar star-like body, and its disc-shaped body usually has five long antennae, but it cannot see its eyes.

Like a pentagram, there are five tentacles and many colors, please adopt it in time, thank you.

Camel petrel (Asterina) is commonly found on the rocky seafloor of Europe

gibbosa)。The northern genera Crossaster and Solaster have many short wrists with a wide disc.

Starfish have a body diameter of 12-24 cm, but the size varies greatly from species to species, ranging from 1 to 80 cm in diameter.

The body surface is yellowish-brown, but some species have bright red, orange, blue, purple and other colors, or a mixture of several colors. The body is in the shape of a five-star, such as a sea disc car, with five wrists extending outward from the ** disk.

The sun starfish can have up to 40 wrists. Most species have a wider wrist near the ** plate, tapering at the end, and a few are similar. The length of the wrist is generally 1-3 times the diameter of the ** disk, but some wrists are up to 4-5 times.

Some species have short wrists, so that the body is pentagonal, like a bread starfish. The central area from the wrist to the ** disc is called the step belt area, also known as the radiation area.

Dear landlord.

If you know how to live, if you can enjoy yourself in a world where colors, sounds, lights, scents, and beautiful scenery are always available, life will become an endless journey of fun.

Much like a pentagram, starfish feed on crustaceans.

Starfish are phylum echinoderms.

Starfish have a peculiar body, the body is like a disk, there are 5 long tentacles like a pentagram, also called a starfish, starfish are widely distributed, there are starfish in the world's oceans, they live in the intertidal zone and near the shore of the calm sea. Most of them inhabit the lower layers of the coast or on the shores of deep waters. There are many kinds, there are more than 50 kinds in our country, there are Roche sea panche like a five-pointed star, bread starfish with a convex hat, petrel with short wrist and blue color, chicken paw starfish with thin wrists like claws and lotus leaf starfish like lotus leaves.

Starfish are bright in color, mostly bright red, dark blue, rose, orange, some will be dotted with purple insect patterns and trim on a pink base, and some will have red edges in blue. Starfish can change their body color as the environment changes, forming a protective color.

It looks very much like a small star.

Features of starfish:

The monitor is "covered in echinoderms – starfish with a peculiar star-like body, usually with five long antennae on its disc-shaped body, but unable to see its eyes. People often think that starfish rely on these antennae to identify directions, but this is not the case. Research by scientists from the United States and Israel has found that starfish are "monitors" all over their bodies.

It turns out that starfish have many tiny crystals on their spiny skins**, and each crystal functions as an eye to get information about its surroundings. Scientists dissected starfish and found that each tiny crystal on the starfish's spiny skin is a perfect lens, known to be much smaller in size than a lens made by humans using existing technology. The myriad lenses in the starfish echinoderm are light-concentrating, allowing the starfish to simultaneously observe information from all directions and keep abreast of its surroundings.

Previously, scientists thought that starfish echinoderm was highly photosensitive, and that it could determine what kind of concealment measures to take through changes in the intensity of light around its body, and it could also change its color to confuse its "enemies". Scientists say this unusual visual system on a starfish has been discovered for the first time. Scientists**, the imitation of this tiny lens will lead to a breakthrough in optical technology and printing technology.

Regenerative ability. The starfish's trick is that it has a doppelganger. If you tear the starfish into several pieces and throw them into the sea, each piece will quickly regrow the lost part and grow into several new and complete starfish. For example, a sand starfish can grow a complete new starfish with a one-centimeter-long wrist, while some starfish are more capable and can grow a complete new starfish with just one stump arm.

Starfish's wrists and body discs are damaged or self-cut, and they can regenerate naturally. Any part of the starfish can regenerate a new starfish.

Hello! Starfish English name: starfish sea star Starfish is a class of echinoderms, which is divided into two families: petrel and sea panche, but people are commonly known as starfish or "star fish".

Starfish are mainly found on shallow seafloor sands or reefs around the world, and we are no strangers to them. However, we know very little about its ecology. The starfish does not look like an animal, and judging by its appearance and slow movements, it is hard to imagine that the starfish is a voracious carnivore that plays an extraordinary role in the evolution of marine ecosystems and organisms.

That's why it's so widespread around the world.

Also translated as star fish; Also known as sea star. Echinodermata is a general term for marine invertebrates of the class Asteroidea, which is not a fish. Flattened, star-shaped.

Wrists. There are 1,800 species in existence, and they are found in all oceans, with the largest number in the northern Pacific Ocean. Spoke diameter 1

Starfish are not fish and are particularly amazing in that they can regenerate without blood and brains.
