Are Irositic crabs oviparous? How hermit crabs are born?

Hermit crabs are oviparous, also known as "white houses" and "dry houses". It is famous for its fact that it often eats shells and other mollusks, taking other people's shells for itself. Hermit crab is mostly found along the coast of the Yellow Sea and the southern seas, and can usually be found in the rocky crevices of the beach and seaside, and sometimes it can be found in bamboo knots, spike coconut shells, corals, sponges, and other places.

As it grows, it will change to a different shell to live in.

Oviparous, hermit crabs have not yet been artificially reproduced, because hermit crabs are generally carried to hatch after female crabs lay eggs, at this time the hermit crab is very small, must eat plankton in the sea, after many molts, before going ashore to live because the reproduction of hermit crabs and the sea are inseparable, so it is not yet possible to artificially reproduce hermit crabs After mating, the female hermit crab will give birth to a certain number of fertilized eggs (about 1000) in the shell, and temporarily store them in the shell, about 1-2 months, after the eggs are mature ( You can see black spots in the eggs, or small hermit crabs that have hatched).

Hermit crabs have not been artificially reproduced at present, because hermit crabs are generally carried to hatch after female crabs lay eggs, at this time the hermit crabs are very small, must eat plankton in the sea, after many molts, before going ashore to live because the reproduction of hermit crabs and the sea are inseparable, so it is not yet possible to artificially breed hermit crabs After mating, the female hermit crab will give birth to a certain number of fertilized eggs (about 1000) in the shell, and temporarily store them in the shell, about 1-2 months, after the eggs are mature (you can see the black spots in the eggs, or a small hermit crab that has hatched).

The mother crab will take her young children to the beach and release them all into the sea, at which time the plankton state of the small hermit crab has no shell, and they will live in this form in the sea for about 1 year, during which time they will eat smaller plankton and grow up with their skin.

When they grow to the smallest shell they can carry, they will rush ashore with the waves, find the first shell and start surviving with it.

After the hermit crab mates, the female hermit crab will give birth to a certain number of fertilized eggs (about 1000) in the shell, and temporarily store them in the shell, about 1-2 months, after the eggs are mature (you can see the black spots in the eggs, or the small hermit crabs that have hatched), the mother crab will take her children to the beach to put them all in the seawater, at this time the plankton state of the small hermit crabs are without shells, they will live in this form in the sea water for about 1 year, in this year, They eat smaller plankton and shed their skins to grow until they can carry the smallest shells they can carry, before they rush ashore with the waves to find their first shells and begin to live with them.

Although adult hermit crabs live on land, their larvae live in the sea. After mating, the hermit crab lays its eggs in a snail shell and attaches to the abdominal limb prosthetic foot, and the eggs quickly mature and become flea-like larvae.

Two years after growth, the hermit crab grows into a mature female crab and grows about the size of the first segment of the thumb to lay eggs, and the hermit crab colony gathers in the forests near the coast from June to August to release flea-like larvae at the beach on the night when the moon is high. They can release up to 50,000 larvae. Adult hermit crabs are not used to being in the water for a long time, so it is easy to drown at this time, or even be swept away by the waves, which is very dangerous for them at this time.

As a result, they will carefully crawl towards the sea and then leave the water in a backward crawling way, changing direction along the way, facing the land and facing away from the water to reduce the impact of the waves and release the larvae. Some females will climb rocks or cliffs to lay down their larvae. It takes about 5 to 10 seconds for the flea-like larvae to be released.

After hatching, the larvae will temporarily overgrow plankton.

like life. After several shells, flea-like larvae become large-eyed larvae that are close to the appearance of adults, and after one shelling, they become juveniles. At this time, they will land on the coast and live in a snail shell.

Hermit crabs are very interesting sea creatures that often look for shells in nature to shade and protect their soft bodies. Over time, their bodies will gradually become larger, to the point that they will have to try to find a larger shell to accommodate themselves. On the question of whether hermit crabs are parasites or not, the answer is yes.

Hermit crabs are infested by a variety of different pests that do not directly endanger their lives, but they can affect their physical health and lifestyle. One of the common parasites is the shell snail, which uses the body of the hermit crab as a place to grow and reproduce. Shell snails usually lay eggs on the shells of hermit crabs and hatch some small spiral-shaped feet.

These legs twist into a serpentine shape in the body of the hermit crab and penetrate deep into the soft parts of the hermit crab, where they grow and develop. This tends to cause discomfort and distress in hermit crabs, and may cause them to lose their balance and ability to move.

In addition to shell snails, hermit crabs are also infested by bacteria and parasites such as hermit crab lice, rose worms, and large and small herpes simplex viruses. Hermit crab lice usually move from the surface of the hermit crab's body to its soft body and then morph into many proglottids with tiny claws so that they can be fixed to the hermit crab's body. Hermit crab lice can cause the body of a hermit crab to become twisted, sick, itchy, and inflamed.

Rose worms usually grow on certain parts of the body of hermit crabs and can cause slow infection. Herpes simplex virus can affect the nervous system of hermit crabs, causing abnormal behavior or sluggish movement and other adverse effects.

In summary, it is possible for hermit crabs to encounter parasites, which have a negative impact on their health and lifestyle from a biological point of view. In addition, hermit crabs may also be harmed by our actions during human activities, such as the first waste and pollutants we throw away, which may cause a great threat to their living environment. Therefore, we should respect and protect hermit crabs and their habitat to ensure that they can continue to thrive in their own unique environment.

Hermit crabs are not born with shells, they will only go ashore to find shells after the planktonic period of development, and hermit crabs will also change their shells with the size of this cover during the growth process. Hermit crabs often use shells, snail shells, and conch shells, but nowadays, in the harsh ecology, hermit crabs can occasionally be seen using bottle caps. Hermit crabs are omnivores, with a lifespan of two to five years, and are known as scavengers by the sea.

Hermit crabs are born with no shells.

Newborn hermit crabs do not have shells, all the hermit crabs we see on the beach carry shells that they find after birth, usually hermit crabs will only go to the shore to find shells after the planktonic period of development, and the shells they live in will be replaced after they grow to a certain extent.

Hermit crabs usually live in the shells of mollusks, the role of these shells is to protect its soft belly from damage, the common "house" of hermit crabs has shells, snail shells, and conch shells, but now the ecological environment is gradually worse, and sometimes we will see them living in bottle caps.

In the case of the conch, the hermit crab will attack the conch when it is looking for its shell, tear it apart and burrow into the conch after killing it, then hook the top of the conch with its tail, support the inside of the conch with its short legs, and finally crawl on its long legs.

Hermit crabs are omnivorous animals that can feed on algae, food scraps and even parasites, hence the fact that they are also known as seaside scavengers. Hermit crabs have a short lifespan, usually only two to five years, but if a good environment can be provided for hermit crabs, their lifespan can be extended to 20 to 30 years.
