They are mostly found on the ocean floor and move on a flat, broad muscle called a foot, which leaves a slimy trail. Some can swim short distances by flexing their muscles. They move at a speed of around 10m per day.

Do nudibranchs move?
Nudibranchs move on a flat, broad muscle called a foot, which leaves a slimy trail. While most are found on the ocean floor, some can swim short distances in the water column by flexing their muscles. ... Aeolid nudibranchs can use their cerata for defense.
How long does a nudibranch live for?
Nudibranchs are simultaneous hermaphrodites, and can mate with any other mature member of their species. Their lifespan varies widely, with some living less than a month, and others living up to one year.
What is special about nudibranch?
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.
Can you touch nudibranchs?
You see, the nudibranch packs a punch—in a very unusual way. Nature is much like a museum: Look, don't touch, no matter how pretty the thing you want to touch may be. That's especially true for vivid critters, which may well be advertising their unpleasantness. Take the nudibranch.
Can nudibranchs survive out of water?
In the case of nudibranchs with a thin skin, which is also used for gas exchange, they can remain alive for some hours as long as they remain damp.
Do nudibranchs have gills?
Anatomy & Ecology: Nudibranchs have no gills. They breathe through their skin or through secondary gills (also known as ''naked gill'') that are found on their backs. A group of Nudibranchs (Cladobranchia) also have some brightly coloured organs on their backs called cerata(in Greek cerata= horns).
Do nudibranchs have eyes?
Nudibranch eyes are located on the head, just at the base of structures called rhinophores (we'll look at these in more detail in a bit). ... These structures have special receptors that allow the nudibranch to sense chemical cues in the water, enabling them to find food and avoid predators.
Are nudibranch reef safe?
Nudibranchs are an incredible sea animal that are commonly found along coral reefs. ... Others are perfectly reef safe and devour nuisance algae. Usually bright in color, and a clear warning to predators, nudibranchs are not consumed because they store poisonous chemicals in their tissues.
Why did nudibranchs lose their shell?
Why do nudibranchs lose their shell? There is much debate about this, but what we do know is that the loss of the shell gave the Sea Slugs the opportunity to experiment with all sorts of body shapes and to experiment with the brilliant and spectacular colour patterns for which they are so well known.
Do nudibranchs have brains?
Akira Sakurai and Paul Katz of Georgia State's Neuroscience Institute study the brains of sea slugs, more specifically nudibranchs, which have large neurons that form simple circuits and produce simple behaviors. In this study, they examined how the brains of these sea creatures produce swimming behaviors.
What are nudibranch eggs?
Giant nudibranch's eggs laid at the base of its food, the tube-dwelling anemone. Each dot is an egg. © Jackie Hildering. To follow up on last week's posting about the feeding of giant nudibranchs, “Who's eating who”, I now share images of the giant nudibranch swimming and of its egg-laying behaviour.
Is nudibranch a fish?
Nudibranchs (/ˈnjuːdɪbræŋk/) are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. ... The word "nudibranch" comes from the Latin nudus "naked" and the Ancient Greek βράγχια (bránkhia) "gills".
Can I have a nudibranch as a pet?
The short answer is no. I would not recommend keeping nudibranchs to anyone (for several reasons). They are extremely hard to keep fed. Lets say you have a sponge-eating nudi like a Phyllidia.
How do nudibranchs survive?
But for most “nudibranchs” the need to hide in a shell has been replaced by either a noxious chemical deterrent system, or the use of stinging cells acquired from the slugs own prey. Other large shelled species like abalone cannot flee into their shell, but instead hold tightly to the substrate to avoid being eaten.
