Starfish don t seem to have mouths, so how do they eat?

There are many beautiful creatures in the sea, and one of them is very popular with everyone, which is the starfish, which looks like a five-pointed star in the sky.

It's the same, but it comes in a variety of colors, and it looks very good, many people know that the starfish is actually an animal in the sea, but it looks like a plant, and many people think that starfish don't have mouths, and they don't know how they eat, in factThe starfish just doesn't look like it has a mouth, its mouth is on the back, which is the place where the five horns converge, the ** part of the body.

Although the starfish has a mouth, it has no teeth, so it cannot chew food well, and when the starfish eats, it sucks food directly into its body, and then allows the food to be slowly digested in its own body. Although the starfish looks docile and cute from the outside, and often lies motionless on the bottom of the sea, in fact the starfish is one of a kindCarnivores, and generally if an animal is targeted by a starfish, it will be particularly miserable. We all know that seafood has suckers on its body, that is, those horns that look like stars are its claws, these claws have suckers on them, once it is targeted, it will suck its own suckers on the opponent's body, and then swallow other opponents into its stomach.

Starfish generally feed on small crustaceans.

Like there are some shellfish.

Algae, as well as small fish, starfish can eat them, the starfish's stomach digestion is very strong, once it catches those prey, it may slowly spit out its stomach pouch, and then dissolve these animals, absorb some energy, and some starfish are by eating plankton in the ocean.

to provide the energy you need. In addition, in fact, there are many types of starfish, and everyone usually sees starfish with only five tentacles, in this case, everyone thinks that starfish are like stars, with only five claws. And in the deep sea, in fact, there is a very large starfish, like this kind of large starfish, can even have more than 50 claws, you can imagine sucking more than 50 claws together on the body of a certain animal, it is really very terrifying.

In real life, most people use starfish as an object to appreciate, and many people use starfish drying as a decoration, but in fact, starfish can still be eaten seafood. <>

In ordinary life, we rarely see people eating starfish, because the skin of the starfish is relatively rough and not suitable for eating, so if you eat seafood, you will break the legs of the starfish, and then eat the starfish seeds inside, starfish seeds, mainly in the autumn There are some female starfish It has to lay eggs to have a lot of starfish seeds.

Although they don't have a mouth, their stomach can spit out and digest the food directly, so that they can finish eating.

Do you know how starfish eat.

Starfish seeds, reproductive disorderly glands. The meat of the starfish is very small, and the legs of the starfish should be broken off at home, and only the seeds and gonads in the middle of the starfish should be eaten, because the shell and antennae of the starfish taste like sand and the taste is not good, so the starfish can only eat the seeds and gonads.

Starfish: Starfish are the most representative group of echinoderms with structural physiology. The body is flattened, mostly symmetrical with five radiations, and the demarcation between the body disc and the wrist is not obvious.

When living, the mouth faces down, and the mouth faces up. The ventral side of the wrist has a step groove, and the groove protrudes from the tube foot. The bony plates of the endoskeleton are connected by connective tissues, which are flexible and flexible.

The body spine has spines and fork spines, which are protrusions of the bones. The membranous vesicular protrusions protruding from between the plates of the bone are covered with epithelium, lining the epithelium of the body cavity, and its inner lumen is connected to the secondary body cavity, called the skin gills, which have the effect of respiration and the diffusion of metabolites to the outside world. The water pipe system is well developed.

Ontogeny of transfeathered brachial larvae and brachycarpal larvae.

Starfish have mouths.

The starfish's mouth is in the middle of its underside and is in direct contact with the surface of the object that the starfish crawls on. Starfish have a peculiar star-like body, and its disc-shaped body usually has 5 long antennae, but it cannot see its eyes. People often think that starfish rely on these antennae to identify directions, but this is not the case.

Research by scientists in the United States and Israel has found that starfish are "monitors" all over their bodies. Be careful.

It turns out that the starfish has many tiny crystals on its spiny skin**, and each crystal can play the function of an eye, these crystals enable the starfish to observe information from all directions at the same time and grasp the surrounding situation in time, so the starfish is an out-and-out 007.

In addition, the starfish also has a doppelganger technique, if the starfish is torn into several pieces and thrown into the sea, each piece will quickly regrow the lost part, thus growing into several new starfish. Because the starfish has such an amazing ability to regenerate, it is a trivial matter for the clan to have a broken arm and a missing limb.

1. Since the starfish does not have eyes, it relies on a variety of chemoreceptors on its body to find food. As they slowly approach their prey and quickly catch their opponents with their wrist legs, they wrap their entire bodies around their prey, and then spit their appetite out of their mouths.

2. Next, the digestion enzyme in the stomach is quickly released to the prey, which dissolves the prey and then sucks it in. This digestion is called in vitro digestion, and the whole process is similar to that of a spider spitting digestive juices on food and dissolving them before resorbating them.

Summary. If you have a starfish that doesn't eat, there could be a few reasons:1

New environment acclimatization: If you have recently placed your starfish in a new aquarium, it may take some time to acclimatize to the new environment. During this time, it may reduce or not eat.

Make sure to provide good water quality and temperature, and give the starfish the right amount of time to acclimatize to their new surroundings. 2.Poor food choice:

Starfish usually feed on benthic animals such as shellfish, shrimp, and small fish, and they may refuse to eat if you give them food that is not to their liking. Experiment with different types of food to find the right one for your starfish. 3.

Illness or health problems: If a starfish does not eat for a long time, it may be because it is sick or has a health problem. This is when you need to check that the water quality and temperature of the aquarium are suitable, as well as whether the starfish has any other abnormal symptoms.

If available, it is advisable to contact a veterinarian immediately for diagnosis and**.

If you have a starfish that doesn't eat, there could be a few reasons:1Adaptation to the new environment:

If you've recently placed your starfish in a new aquarium, it may take some time to adjust to the new environment. During this time, it may reduce or not eat. Make sure to provide good water quality and temperature, and give the starfish the right amount of time to acclimatize to their new surroundings.

Can you add, I don't quite understand it.

4.Overfeeding: Overfeeding can also cause starfish to not eat.

Make sure you keep an eye on the starfish as recommended and clean up any uneaten food debris. If the starfish does not eat for a long time, please check the water quality and temperature of the aquarium first, then try different types of food, and contact the veterinarian for diagnosis if you have any abnormal symptoms.
