Nudibranch basic facts
Pronouced noo-de-brank
Scientific name: Nudibranchia
The nudibranch is a plankton.
A plankton is a small organism that floats in fresh water.
The nudibranch is also a decomposer.
A decomposer is an organism that decomposes organic material.
Nudibranchs move,or 'crawl', on the muscular action of a flat foot, which leaves a slimy trail.
Some can swim by flexing its foot muscle.
Body Structure
The nudibranch has a rhinophore, which are two horns on the top of it's head.
Nudibranchs also have a slimey shell.
Nudibranchs have cool patterns because of the pigments in the food they eat.
They have a muscle called a foot in which they use to move.
Reproduction
Each nudibranch is both male and female producing sperm and eggs. To mate, two nudibranchs come together side by side and pass sperm sacs through a tube in their 'neck' to each other. Then they both lay eggs.
Avoding and Catching Prey
Since the Nudibranch doesn't have many predators they can easily hide. The Nudibranch usually uses its colors to camoflauge with the enviroment. This also helps them catch prey.
Nudibranchs belong to the organism "Opisthobranchs".
Relatives
Sea Pens
Snails
Spanish Dancer
Bubble Shell
Leaf slug
Side-grilled slug
Sea Hare
They are very photogenic

Nudibranches, Green Sea Wrasses, Yellow Corris Wrasses, True Peppermint Shrimp, and the Copperband Butterfly eat Nudibranchs.
Why are they important?
Since Nudibranch are marine invertebrates, they are evidence that there are other living creatures in the area
Help understand evolutionary process
Help understand the evolution of mollusks
Nudibranchs can be used to make medicines for humans to help bad conditions
Live
Nudibranchs mainly live in the ocean(salt water). They can be found in tide pools and deep water too.
Danger
Oil spills and plastic in the ocean can threatin the lives of nudibranchs.

Unless your the nudibranchs prey, nudibranchs do not endanger other organisms.
