How does sea slug move?
Like other gastropods, most sea slugs move slowly by waves of contraction that lift part of the surface of the foot, which is lubricated with mucus, but are unencumbered by a heavy shell. Some, such as the ‘sea butterflies’, swim in the plankton, while others can swim only for short periods.
Do nudibranchs have muscular foot?
Most nudibranchs have a muscular foot which can be modified for particular situations. In species which live on soft sand, like Cerberilla the foot is very broad and ciliary gliding predominates over muscular waves, while in large dorids forward movement is almost totally dependent on the wave of muscle contraction.
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.
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).
How do nudibranchs adapt to their environment?
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.
Is there a rabbit in SpongeBob?

Do nudibranchs have gender?
Nudibranchs are ‘gender-fluid’ Nudi’s are hermaphrodites, so they can’t be categorised female or male, but are rather a mix of both sexes. This comes in very handy, as (as mentioned in the fact before) finding a mate can be a very, very frustrating task for the little slugs.
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.
