How do hydroids hunt and digest them?

The tentacles catch the prey, stutter it, and digest it in the digestive cavity.

Hydra feeds and excretes from the mouth, which says something.

Hydra. The body captures food with its freely retractable tentacles, the food, curls it into the mouth, and swallows it.

Methyl bodies, at different stages of development, are able to swallow bait in different sizes. For example, in the 4-tentacle stage, the whole nauplii of the abundant insect cannot be swallowed, but in the floating larval stage, it can smoothly swallow the shellfish.

The larvae of the trochal, when attached to the polyps after a few days, can devour crustaceans.

of nauplii, telepods and small copepods, etc. The amount of food that the polyps eat.

Small, especially the polyps with 4 and 8 tentacles, feed 50-200 splanktonic larvae or trachala larvae per day, or feed on the auplii of the abundant insects.

There are tentacles around the mouth, which are tools for predation.

If you have any questions about this answer, please ask, and if you think mine is helpful to you, please don't forget it!

Apprentice. You're not done with creature yet, are you?

I've helped so many people...

I just didn't help you.

Don't you hate me very much...

Haha. I'll help you next time...

Hee-hee......

Hydra is a multicellular invertebrate, food in the digestive cavity of the hydra, there are two digestion methods: intracellular digestion and extracellular digestion Because there are many cells in the endoderm that can secrete digestive juices, the digestive juices secreted by these cells enter the digestive cavity, therefore, the food is extracellularly digested in the digestive cavity At the same time, because there are some cells in the endoderm, the food can be encapsulated in the cells, so the food can also be digested intracellularly The nutrients after digestion are absorbed by the endoderm cells. And the various parts of the body that are transported to the undigestible food scraps, which are still excreted from the mouth to the outside of the body

So the answer is: intracellular digestion; Extracellular digestion.

Food is digested in the digestive cavity of the polyp in two ways: intracellular digestion and extracellular digestion. Since there are many cells in the endoderm that secrete digestive juices, the digestive juices secreted by these cells enter the digestive cavity, so that food is extracellularly digested in the digestive cavity.

At the same time, because there are cells in the endoderm that can encapsulate food particles into the cells, the food can also be digested intracellularly. The digested nutrients are absorbed by the endoderm cells and transported to all parts of the body. Food debris that cannot be digested, is still excreted from the mouth to the outside of the body.

Hydras are aquatic insects, and they belong to the order Dragonflies. In terms of food and predation methods, the hydra is a very special insect. Hydroids can be very flexible in the water to prey on insects such as insects, moths, aphids and other insects flying above the water surface, and have a very high success rate of predation.

While hunting, hydras can launch surprise attacks from all directions to capture their prey. They can dive into the water to lurk and wait for their prey, or they can spread their front paws to stick to a swimming insect and then grab it with the barbed hooks on their hind legs. In addition, the hydra can quickly swim towards its prey, then clamp it in half and swallow it.

In terms of defense capabilities, hydras also have certain defense mechanisms. The hair on the surface of their body can reduce their exposure to parasites and bacteria, while also reducing their odor by rubbing their body to avoid detection by predators. In addition, hydras can also use their adhesive feet to escape quickly.

In summary, hydra can prey on food from all directions, and it also has a certain defense mechanism when matched with high temperatures.

Hydroids are aquatic insects that can usually hunt their prey from all directions. Their forelimbs are long and strong and allow them to quickly catch their prey, while their hind legs are specialized as swimming organs that allow them to quickly traverse the water to chase their prey. In addition, hydroids can also use the sensors on their heads to sense the movement and direction of their prey, so as to better prey on prey.

Hydras also have some defensive capabilities, and they can use their shells and some special structures to protect themselves. For example, their head and thorax are protected by a hard shell, while they have many small spines on their abdomen and back that can make it uncomfortable for potential predators. In addition, hydras can also use their ability to fly in front of them to escape from danger.

Hydras are highly adaptable freshwater creatures that can be adapted from all directions to prey on tiny aquatic animals through mucus and wriggling around their bodies. At the same time, they can also defend themselves against predator attacks by curling their bodies into balls, or twist their bodies in other directions to escape threats.

Hydroids have sharp antennae and can detect faint vibrations in their surroundings to determine the presence of prey or predators. When hunting, the hydra can quickly approach its prey from all directions and use its powerful mouthparts to trap it and suck bodily fluids.

In conclusion, the polyp has flexible locomotion and excellent predation skills, allowing it to hunt and defend from all directions.

Hydra can prey and defend from all directions, and the action is relatively flexible, there are posture pants in various parts of China and survival, living in the water filial piety all the year round, clever and very strong.
