Are nudibranchs poisonous to humans?
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.
Why are nudibranchs poisonous?
Many nudibranchs eat anemones, corals, jellyfish, or hydroids, which all have stinging cells called nematocysts. These specialized cells contain a toxin on a harpoon-like dart that is discharged when touched. Some absorb toxins from their prey and emit them in a noxious mucus.

Nudibranchs usually stay near their food, such as sea anemones, sponges etc., which will also die if they dry out. Since their food will only grow in areas that stay wet, nudibranchs are usually safe from being caught out of water. Good Luck with your project, Bill Rudman.
Are nudibranchs important?
Nudibranchs are important indicators of declining ocean conditions, too. “Nudibranchs are more than just colorful ambassadors for the coral reef systems they inhabit,” says Johnson. “Documenting their diversity and monitoring their regional presence helps us understanding how ecosystems are faring.”
Can you keep Blue Glaucus?
In recent years, the internet has caused the species to become very popular, although its fame has been detrimental. Many people want to add them to their aquariums, leading to an increase in their appearance in the exotic pet trade. However, keeping the Blue Glaucus as a pet is impractical because of its diet.
