Nudibranchs, pronounced 'noodibrank', are a mollusc - basically speaking - a slug, and come in an enormous variety of sizes and colours.
Nudibranch itself means 'naked gills'. the plumes you see on them are literally their gills for breathing.
They are found in most habitats in all the oceans of the world.
Most nudibranchs are carnivorous. Some feed on sponges, others on hydroids, others on bryozoans, and some are cannibals, eating other sea slugs, or, on some occasions, members of their own species. Other groups feed on tunicates, barnacles, or anemones .
Nudibranchs mainly live in the ocean(salt water). They can be found in tide pools and deep water too. Most abundant in tropical waters, they are also found in arctic waters and everything in between too. There are even a few species that live in fresh water!
Nudibranches
Nudibranches do eat coral.
they don't have one. That's what defines them as nudibranches.
Most nudibranches live about one year. The tropical Sea Hare nudibranch can live as long as 6 years in an aquarium.
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.
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)
