Euthyneura
Nudibranch/Class
nudibranch, also called sea slug, any of the marine gastropods that constitute the order Nudibranchia (subclass Opisthobranchia of the class Gastropoda). Nudibranchs possess a radular feeding organ, but they characteristically lack a shell, gills, and mantle cavity typical of other mollusks.

How many species of nudibranch are there?
There are more than 2,000 known species of nudibranch, and new ones are being identified almost daily. They are found throughout the world’s oceans, but are most abundant in shallow, tropical waters.
How do I identify a nudibranch?
Basics and Anatomy for Nudibranch Identification (in short) The pompom on his back is a branchial plume, gills to filter oxygen from the water (breathe). This is typical for dorid nudibranchs. Some species have more tentacles; some facing forward (oral tentacles), some facing to the side (propodial tentacles).
What is a nudibranch and what is special about it?
Nudibranchs are a group of soft-bodied, marine gastropod molluscs. Some are known for their extraordinary colours and striking forms, and they have been given fun nicknames to match, such as “sea goddess”, “splendid”, “dragon”, “painted” or ‘dancer” just to name a few.
Is nudibranch a cnidarian?
Stinging cells, produced by cnidarians such as jellyfish and anemones, are one of ocean creatures’ most effective defences. Nudibranchs, commonly known as sea slugs, are a group of shell-less marine molluscs. …
What makes nudibranch unique?
Is nudibranch same as sea slug?
Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs.
Are nudibranch endangered?

Nudibranch/Extinction status
Are nudibranchs rare?
Cerberilla pungoarena (Collier & Farmer, 1964) is one of those rare nudibranchs you may never see: only a few subtidal specimens have been reported since the mid-2000s. Nudibranchs are shell-less marine molluscs commonly called sea slugs.
What are the two types of nudibranch?
Meanwhile, the nudibranchs are commonly divided into two main types, dorid nudibranchs and aeolid or eolid nudibranchs:
- Dorids are recognised by the branchial (gill) plume, which forms a cluster on the posterior part of the body, around the anus.
- Aeolids have cerata on their backs, instead of the branchial plume.
What is the taxonomy of the Nudibranchia?
The taxonomy of the Nudibranchia is still under investigation. Meanwhile, the nudibranchs are commonly divided into two main types, dorid nudibranchs and aeolid or eolid nudibranchs:
Where do nudibranchs live?
Nudibranchs occur in the shallow waters of all the world’s oceans, where they feed chiefly on other invertebrates, particularly sea anemones. Those of the family Tethyidae can swim.
What are the Predators of nudibranchs?
Navanax inermis[..] is the bane of all nudibranchs, because it is one of the few known predators on this group of slugs. […] Dorids mainly eat sponges, bryozoans and tunicates, whereas eolids principally eat cnidarians.
Are nudibranchs and sea slugs the same thing?
Nudibranchs are one of the groups which are informally known as sea slugs. This is a term which includes other Gastropod groups which look similar to nudibranchs. Sea slugs is an informal term; it is not a monophyletic group. The body forms of nudibranchs vary greatly.
