Protect

　Does not have a shell, the sea slug, though it is likely to be bright and striking color, why is it that you do Will not eat exhausting. Instead of the shell you've shed, I was wearing a lot of defenses.

1. First, the sea slug is looking at itself, and see in the surrounding environment is very colorful and beautiful, but it does not stand out at all in keeping well. Can not I find also quite looking sea slug, you would not do it more often has not been found. The fact that there is not a place where many prominent sea slug is hiding in the shadows. Among the sea slug, that takes some of the seaweed and sea sponge of food the dye, together to mimic the color of the body in that color.

Where is sea slug?

2. Even if the enemy found, if　sea slug is very bad taste and mouth trying to eat, sea slug is more likely to survive. As a matter of fact, sea slug are very bad taste, it's likely not something like eaten very much. The reason why the very bad taste, because sea slug is likely to eat something very bad taste food. In fact, I want the person who tried to eat sea slug. As a result, the act is more likely to feel the danger gave up on edge just licking the tongue. It also has the belief that I eat anything, a famous people  Masanori Hata(Mr.Mutugoro) in the essay,  seems to have written had he not eat only sea slug.Some people have tried, from a sense of crisis, would not spit swallow, one day after a chemical smell that seems to have stuck to the nose and mouth.

3. As Mino-sea slug, eating cnidarians sea slug, the store nematocysts cells that eat into the body,In case of emergency, release the cells that store nematocysts. Not only get energy from food in order to live, sea slug are used as a means of defense. I has achieved just to kill two birds with one stone. When the enemy in the mouth, the attack is carried out all at once nematocysts. In the mouth, it is the battlefield. Stimulation of Mino-sea slug, erect Mino.

Mino sea slug

4. Mino sea slug kind of sea slug, upon receiving a strong stimulus from the outside, Mino projections autotomy. Mino was autotomy is about one hour seems to work. As lizards, by cutting themselves a part of the body, I am running away from predators.

5. Such as sea sponge and sea moss from the sea slug of feed,and  generating chemicals to protect themselves, such as terpene-phenol-steroids. Sea slug can also escape from predators or to secrete substances such science, or by light emitting light.

In this way, the law is on parade of defense. Equipped with one or more of these, and protect themselves from predators. However, it is not perfect defense of these laws. It has been confirmed that increase the survival experiments, that it is not 100% protection be provided with these protective methods have been reported.

Food

　Sea slug is alive for some period of time and there is no food, but sea slug will become progressively smaller and die. You think the image of a sea slug is strong vegetarian, I most of the sea slug is actually carnivorous. Vegetarian is said to be the minority. You seem quite broad and say what do you eat. However, there are many in the sea slug unbalanced diet, it seems that there are few species of various food one eats.
　
　Then, an introduction about the diet of sea slug .

  Among the wide variety of sea slug, that has gained some energy from the sunlight as other plants. Gokurakumidorigai fellow food seaweed, there are those stored in your body without having to digest the only kind chloroplast from green leaves eaten as food, energy can be obtained thereby perform photosynthesis. Also change the color of the body of the sea slug by chloroplast pigments taken into the body. Finding a sea slug of the same color and texture of bright green seaweed sounds like quite a high degree of difficulty.

 Copulation

  There is no distinction between male and female in the sea slug. Sea slug of one animal has both genitals. However, it is not only lays eggs in the sea slug of one animal on its own. Segment folder for blood to become thick and mating with another individual.A small sea slug for very difficult to find a partner in the world of the open sea. Even if you are able to finally meet each other male and female among I can not leave descendants. If hermaphrodite, you will be able to carnal knowledge without confirming the gender of the person, both lay eggs. Sea slug mating is performed by combining the reproductive tract of each other on the right side of the body. Shape of the egg is massive and many other spiral, ribbon-like, tangled, the number of eggs that lay at one time spans up to 2 million units.

　Some types can be not only to fertilize the egg of his sperm got from the other party, to absorb as a nutrient source.Encounter between the sea slug is sometimes not always a happy ending, if one ate the other party. In particular, it seems often the case when different species.

Scene of mating sea slug

　By the way, the explanation of sea slug's in "Animal Forest" game for Nintendo's wildly popular, ... What "The Marriage of sea slug, which is also the female is also a male. Ones daring to marry with anyone if someone who met anyway," seems to is. And　we are so that you can fish all day and the sea slug, in the sea all year round. In addition, 200 Bell and the price of sea slug seems pretty cheap.

　But I also believed that spawning major event held in the second half of the short life that lay eggs, the life of the sea slug is nearing the end for the sea slug that can not be raising children. The timing of spawning of sea slug is not necessarily determined, naturally spawning the mating between a mature sea slug If sea slug encounter. Seems faster growth of sea slug and egg hatch in the southern island of warm  sea ,and egg hatch is also can be seen all year round egg of some kind of sea slug.

Berija larva 

　Period from egg to larva until the birth, which varies by the type and temperature of the external environment, it seems that many things to hatch in about 1-2 weeks. Just called　Berija  larvae was born, to live suspended. Berija larva has a shell and cilia, when the floating life while eating such as plankton, found things to be their prey, an epiphyte on their prey, changes in the shape of a sea slug. In many species of sea slug, shell is shed at this time, some kind of growing the shell as it is admirable.Some things that are in the shape of a sea slug from the time they hatch from eggs as larvae without floating Berija life in a part of the companion of sea slug.
