Nudibranch diet


Some nudibranch species are solar-powered. If you intend to preserve your specimens they should first be relaxed to retain, more or less, their original body shape. Nudibranchs use a variety of chemical defences to aid in protection, [21] but it is not necessary for the strategy to be lethal to be effective; in fact, good arguments exist that chemical defences should evolve to be distasteful rather than toxic.

Some species have venomous appendages cerata on their sides, which deter predators.

Nudibranch Sea Slugs - Facts

Their planktonic prey is trapped by use of a spherical web of mucus, many times the size of their bodies, which is drawn towards the mouth by the action of cilia on the wing surfaces and surrounding lobes. A typical nudibranch spawn coil is shown on the left.

One form of protection is camouflage to blend in with the background and avoid detection.

They move at a speed of around 10m per day. Unfortunately few species can be kept for their full life time in aquaria because their foods particularly sponges, hydroids, ascidians and bryozoans do not fare well in captivity.


Their fragile bodies mean that special techniques must be employed if they are to be collected and kept alive.

They also have a pair of tentacles with scent receptors called rhinophores. They have tentacles on their heads known as rhinophores which can detect taste, touch and smell.

Cold and Warm Water Oceans Weight: For this reason most nudibranchs are found on the ocean bed. Each species has its own unique scientific name Nudibranchs are gastropod molluscs. This large group can be divided into four main types Suborders on the basis of their general appearance.

Nudibranch Facts

When mating, they can normally mate with any adult passing nearby. Sea Slug Habitat and Behavior Sea slugs are found almost anywhere there is water. Population currently stable Type: Doridacea] Nudibranch - scientific name Nudibranchia - is one of over 3, known nematocysts species of soft-bodied sea slugs.

They belong to this sub-class therefore they are all sea slugs, however not all sea slugs are nudibranchs. Do not be alarmed if some species release bright coloured fluids upon collection; none are harmful.

Members of the genus Nembrotha feed on ascidians.The nudibranch absorbs the algae's chloroplasts (zooxanthellae) into the cerata, which acquire nutrients by photosynthesis using the sun to sustain the nudibranch for months. Others have evolved other ways of farming zooxanthellae, housing them in their digestive gland.

The diet of tritoniids is mainly soft corals or gorgonians. Some species are very cryptic upon their prey in having gills that closely resemble the polyps of the host upon which they prey. Some species are very cryptic upon their prey in having gills that closely resemble the polyps of the host upon which they prey.

Nudibranch is a set of components facilitating and automating Grasshopper’s capacity to generate distance-based value datasets, while recording particle traces moving within attractor defined vector-fields, that can be further implemented into animated simulations.

Nudibranchs derive their coloring from the food they eat, which helps in camouflage, and some even retain the foul-tasting poisons of their prey and secrete them as a defense against predators.
