Nudibranchs are a diverse order of marine organisms of the subclass Opisthobranchia,class gastropoda, and phylum Mollusca. These invertebrates are commonly called sea slugs and are popular in aquariums because they are brightly colored. In general these shell-less gastropods can be found in most marine benthic waters, including the Artic . There are even a few tropical fresh water species. Nudibranchs can be separated into distinct sub-orders. Two such suborders are Doridacea, also known as Dorids, and Aeolidaecea, also known as Aeolids . The two can be differentiated by the shapes of their mantles. Their bodies are soft and and detorted compared to their twisted relatives, the snails. Nudibranchs are defined by their exposed gills, thus the name Nudibranch which means "naked gills." Their gills are located on the outside of their body instead of hidden in a mantle cavity. In Dorid nudibranchs, the gills are in flower-like structures are called branchial plumes located on their backs. The gills surround their anal opening, and can be retracted into a gill-pocket on the mantle. The mantle is wide and typically almost entirely encompasses the foot. Aeolids do not have gills, instead they posses tentacle-like cerata made of thin mantle tissue used for respiration and defense. Nudibranchs move using a foot for crawling and by undulating of their body to swim.
Nudibranchs are sea slugs that normally live near reefs. They are very interesting. whenever they eat something that get the shape of that thing and if it is poisonous, all the poison is stored in its body. For example, if one eats a sea anenome, it takes the shape and color of that anenome and all the poison from the tentacles are stored in the new "tentacles" on the new nudibranch's body.
Nudibranches
Nudibranches do eat coral.
they don't have one. That's what defines them as nudibranches.
The nudibranch has plumes on the top of its body, those are gills from which the creature breathes.
Many predators avoid the nudibranch, as they can be toxic. However, some nudibranches will cannibalize others. They are also eaten by some sharks and other large fish.
One group of animals thae eat the Venus Flower Basket are nudibranches,which are sea slugs.
The sea slugs (nudibranches) safely store the anemone's toxins in its body. If a predator attempts to eat the nudibranch, the venom is transferred to the predator.
The reasons why any animal eats a particular organism is never clear. A top reason why Nudibranchs might eat 'toxic sponges' is that there was not much else available to eat and it was easy to eat the sponges. These sponges were a niche that was unfilled and the Nudibranches adapted to take it. The sponges are still partially toxic to Nudibranchs! They often have specially lined stomachs to protect them from the sponges sharp spicules and the toxins from the sponge accumulate in them. When a predator tries to eat a nudibranch it gets a nasty mouthful of these toxins.
Most nudibranches live about one year. The tropical Sea Hare nudibranch can live as long as 6 years in an aquarium.
A Nudibranch is like a slug without a shell. They are known for their amazing color and striking formation. There are almost 3,000 different species. Nudibranches can have many different colors, for example blue with green poka dots.
žNudibranchs are hemaphrodites, meaning they're both male and female, but can't self fertilize. žTo mate two nudibranchs come together side by side and (usually both) pass sperm sacs through a tube on the right behind the head.
Actually all kinds of animals can camouflage - it just depends on where the animal is and how well their skin/fur can match the surroundings:snakes on sandrabbits on snowtigers behind brown grasscrocodiles in swampsetc.However, I am assuming that you mean animals that changes the pigment of their skins in order for them to camouflage. They are:Cuttlefish Species(which includes chameleons)Nudibranches (a small sea creature)Parasite Species (like a Fluke)
