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.
Are nudibranchs poisonous?
Some nudibranchs are poisonous while others pretend to be poisonous, which is evident by their vibrant colors. They feed on stinging cells of hydrozoids and store them in the rear of their body for protection. They can also ingest toxins from sponges and become toxic and inedible. ... Way to go, nudibranchs!
Are nudibranchs poisonous to touch?
Despite the unsavory or toxic taste they can present to their non-human predators, most nudibranchs are harmless to humans, except those like Glaucus atlanticus which consumes nematocytes and so may consider you a predator and sting.
What kind of animal is a nudibranch?
The nudibranch is a cannibalistic sea slug.
Can you keep nudibranchs as pets?
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.
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.
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".
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But for most “nudibranchs” the need to hide in a shell has been replaced by either a noxious chemical deterrent system, or the use of stinging cells acquired from the slugs own prey.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.
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.
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.
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).
What are nudibranchs predators?
Predation. 'Nudis' have few predators and are at risk only from other nudibranchs, turtles, some crabs and humans. Over years of evolution they have discarded their protective shell and so rely on other forms of protection and defence to deter would-be predators.
Where can I see nudibranchs?
You can find nudibranchs in an extraordinary array of environments across the world, from tropical reefs to sub-arctic waters and even hydrothermal vents of the deep. However, the Lembeh Strait in Northern Sulawesi is one of the best paces to spot them, with 200 species (and growing) so far identified.
Do nudibranchs have teeth?
The animals have a set of curved teeth, which they use to eat coral, sponges, and fish eggs off the ocean floor. Nudibranchs use tentacles on their heads to poke around for grub. Check out where nudibranchs live.
Why are nudibranch mollusks?
Nudibranchs possess a radular feeding organ, but they characteristically lack a shell, gills, and mantle cavity typical of other mollusks. The delicately coloured body has bizarre outgrowths, called cerata, which serve a defensive function, discharging nematocysts that the nudibranch has ingested from cnidarian prey.
