    Sea slugs like to live in clean, clear and flowing water, and they feed on seaweed, so there are many sea slugs in areas where seaweed is abundant. The reason why sea slugs can avoid the predation of their opponents is mainly because they have a special ability, that is, what color of seaweed they eat will become what color, so that these predators will not find their traces casually, and some sea slugs have evolved the same body shape as seaweed, so that their camouflage can be more extreme to avoid the pursuit of predators.

    Sea slugs are also called nudibranchs, but nudibranchs are neither rabbits nor slugs, and belong to shellfish that live inshore.

    It is an invertebrate.

    The phylum, gastropod, and bare gills are commonly known for the two pairs of antennae on the top of their heads, which protrude like rabbit ears. Nudibranchs are a special member of the invertebrate family. Their shells have long since decayed into inner shells.

    The reverse side has a thin transparent shell skin, which is generally white in color and has a pearl luster.

    The two pairs of antennae on the top of the head of the nudibranchs are prominently resembling rabbit ears, and the body is smooth or has many protrusions. When the nudibranchs crawl on the bottom of the sea, the pair of antennae behind them are separated into a "figure eight" and stretched forward diagonally, sniffing the smell of the surroundings, and when resting, the tentacles are immediately close together, straight up, just like the two long ears of a rabbit. When it doesn't move, it looks like a little white rabbit crouching on the ground with a pair of ears upright.

    Therefore, it was first called the nudibranching by the Romans.

    Colorful camouflageBecause there is no casing to protect itself, sea slugs have evolved various means to prevent ** eaters from swallowing them. Some sea slugs swallow whatever color of seaweed they swallow. For example, the body of a sea slug, which eats red algae, is rose-red, and the body of a sea slug, which eats Fucus, turns brownish-green.

    Some nudibranchs also have fluffy and reticulate bumps on the skin, which in turn bring the shape of the nudige closer to the surrounding seaweed. Depending on the change in shape, body color and texture of the fish, the sea slug has escaped many troubles.

    The first point is that the habit of life is actually very good, and in it is to swim around and survive by eating creatures in the sea, and the second point is that these animals are mollusks, so they will suck some seaweed, so it is better to survive.

    Sea slugs are also known as "sea unicorns". From the point of view of category, the sea slug belongs to the genus Mulchback Snail of the Phylum Gastropoda Gastropod. Thus, the sea slug is a mollusk.

    From the outside, the shell of the sea slug has degenerated into an inner shell, which has become very thin and fragile, and the color of the shell is white. Their soft parts are turned outwards and can even wrap their shells around. The head of the sea slugs is very large, taking up almost half of their entire body.

    Sea slugs breathe with their gills.

    From the perspective of living environment, sea slugs live in the ocean, hence the name with "sea". Specifically, they are widely distributed in seas around the world, even in cold polar seas. Sea slugs are sometimes found in deep waters, but can also be found at depths of up to 5,000 meters.

    From the perspective of feeding habits, the main food of sea slugs is various algae, and they will have different colors after eating different algae plants. For example, when they eat red algae, their body color turns red; When they eat Fucus officinalis, their bodies turn brownish-green.

    Sea slugs belong to the phylum Gastropoda of the phylum Gastropods, so they belong to animals and are mollusks and not plants. As mollusks, some of the characteristics of sea slugs are also more pronounced. For example, their bodies are softer, and their locomotor organs are feet, so their movements are relatively slow.

    Sea snails are shellfish. Shellfish refer to a group of mollusks that have shells, including monoplana, polyplate, cephalopod, bivalve, and gastropod. The sea snail belongs to the phylum Gastropoda of mollusks, so it is a type of shellfish.

    Outwardly, the sea snail also conforms to the basic characteristics of shellfish. The exterior of their bodies, like other shellfish, has a relatively hard shell that protects itself. <

    Shellfish are a general term for a large group of animals, they are all mollusks, and they are a class of mollusks with shells. Shellfish themselves contain many species, and their common feature is that they have an outer shell on the outside of their bodies. The shape and color of the shells of different shellfish are different, and sometimes the differences are quite large.

    Shellfish include animals in the class Monoplanidae, Polyplanda, Cephalopodida, Bivalves, and Gastropoda.

    The sea conch is also one of the marine animals that we can often see. In terms of category, the sea snail belongs to the phylum Gastropoda and is also a type of shellfish. As shellfish, conch also conforms to the basic trait that they have an outer shell on the outside of their body.

    The shell of the conch is relatively thick, the outline of the edge is square, and the height of the shell is about 10 cm. It can be seen that the sea snail can be said to be a more typical shellfish.

    As mentioned above, shellfish are all mollusks, which are a group of mollusks with shells. The sea snail is also a type of shellfish and therefore necessarily belongs to the mollusk as well. In fact, from the class to which the conch belongs, it is also obvious that they are mollusks, because the conch belongs to the phylum Mollusk.

    As mollusks, they also conform to many characteristics of mollusks, such as having no backbone, having a soft body, and having a degenerative true body cavity.

    The animals of the sea are: there are more than 200,000 species of marine animals, and they have a variety of forms, ranging from microscopic single-celled protozoa to higher mammals - cetaceans; Marine animals can be divided into three large groups: marine invertebrates, marine protochordates, and marine vertebrates.

    1. Sharks. Sharks have been on Earth since 300 million years before the appearance of dinosaurs, and they have been around for more than 500 million years, and they have barely changed in nearly 100 million years. Sharks, known as sharks, sharks, and sand fish in ancient times, are behemoths in the ocean, so they are called "wolves in the sea". The conventional wisdom is that sharks' cartilage (i.e., shark fins) is high in protein, but this is wrong.

    Eggs have far more protein than shark fin. In addition, studies have shown that sharks are prone to mercury accumulation and shark fins contain a certain amount of neurotoxins, which are potentially harmful to humans. Sharks are at risk of extinction because of decades of mass hunting.

    2. Whales. Whales are divided into two categories, one is baleen whales and the other is toothed whales. Whales belong to the phylum Chordates, subphylum vertebrates, mammals, and eumatria, which contain about 98 species of viviparous mammals living in oceans and rivers.

    There are more than 30 species in China's waters. All but a few species of whales live in freshwater, and all but a few inhabit the ocean. The definition of the whale itself is vague, and the whale can encompass all cetaceans, as well as specific families of cetaceans. All dolphins are also included in the whales.

    3. Octopus. Octopus: It is the general name of 252 species of marine mollusks in 26 genera of the octopus family. It is the largest family of cephalopods, which can be divided into the subfamily of deep-sea myriapods, the subfamily of Aerdoudae, the subfamily of cephalopods and the subfamily of cephalopods.

    The body is ovate or oval, muscular, the mantle cavity has a narrow opening, and the body surface is generally without water holes. Wrist suction cups 1 or 2 rows.

    The third carpal stemmed on the left or right side of the male, with a seminal groove on the ventral margin of the wrist and a spoon-shaped lingual lobe at the end; The stemmed wrist cannot be self-broken. Funnel jacket lock degraded. 1 pair of vestigial needle-like inner shells or no inner shells. If there is a toothed tongue, the teeth on the side of the tooth tongue are usually single-cuspid. The stomach and cecum are located at the back of the digestive glands.

    Fourth, jellyfish. Jellyfish: It is an important plankton in the aquatic environment and belongs to the class of spinophiles. Jellyfish are a very beautiful aquatic animal.

    Its body is shaped like a transparent umbrella, and the diameter of the umbrella body can be large and small, and the diameter of the umbrella body of the large jellyfish can reach 2 meters. The edge of the umbrella has a number of whisker-like tentacles, some of which can be up to 20-30 meters long.

    5. Sea turtles. Sea turtles belong to the order Turtles, Turtles, and Turtles. It is widely distributed in the Atlantic, Pacific and Indian oceans. Chinese sea turtles are found in the coastal waters of the Beibu Gulf from Shandong in the north to the south of the Beibu Gulf.

    It can be more than 1 meter long and has a lifespan of about 150 years. There is a pair of forehead scales on the top of the head. The limbs are like oars, the forelimbs are longer than the hind limbs, and each has a claw on the inside.

    The head, neck, and limbs cannot be retracted into the nail. Feeds mainly on seaweed.
