Sea anemones can sting and are poisonous. After cleaning the toxins, they are edible, not jellyfish.

There are many types of sea anemone toxins, most of which are neurotoxic or myotoxic, containing peptides, proteins, trigonelline, lobster myotine, histamine, 5-hydroxytryptamine, etc. Studies have shown that When the sea anemone launches toxins, the osmotic pressure in the body reaches 2000 gravity acceleration, and it only takes 0.02 seconds to complete the launch.

There is a huge red sea anemone growing in the Hawaiian sea. Its toxin is extremely poisonous, and the locals often use it as curare. The sandstone sea anemone growing in Bermuda is more toxic and is known as the most powerful biotoxin in the world, much more powerful than potassium cyanide.
