How can you tell a marine flatworm from a nudibranch?
Marine flatworms typically have a flat, ribbon-like body with distinct bilateral symmetry, while nudibranchs have a soft body with external gills on their back and often colorful patterns. Additionally, nudibranchs belong to the mollusk group, while marine flatworms do not.
What are nudibranches?
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.

Are nudibranchs endangered?
Si. It is not.
Do water stick insect have gills to breathe in water?
Stick insects do not live in water. However, insects that live permanently submerged in water for part of their lives (such as mayfly larva) do have gills. Others like mosquito larvae do still come up to the surface to breath air and still others like water beetles carry a bubble of air with them underwater.
Where do Nudibranches live?
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!
What is the collective noun for nudibranchs?
The collective noun for nudibranchs is a "bloom." This term reflects the vibrant and colorful appearances of these sea slugs, which are often found in large groups. Nudibranchs are known for their diverse shapes and patterns, making a bloom of them a stunning sight in marine environments.
What organism eats bryozoa?
Nudibranchs eat bryozoans
Do creyfish have lungs or gillks?
Gills. Animals living in the water that do not come up for air use gills to breathe.
What eats nudibranchs?
Nudibranchs are preyed upon by various predators in their marine ecosystems, including fish, crabs, sea stars, and certain species of sea slugs. These predators are attracted to nudibranchs due to their bright colors, which can serve as a warning signal or camouflage, depending on the species.
What is the scientific name for the nudibranch?
well there are tons of types of nudibranchs. i suggest this site for more info: http://www.freebase.com/view/base/scubadiving/views/nudibranchs i know its long but enjoy! :)
