Anemones
Anemones are simple animals that look like delicate flowers. But these “flowers” can move and catch prey.
Anemones have poisonous barbs in their tentacles that fire on contact, injecting poison into their prey.
To protect themselves, anemones secrete a special slime that prevents the stinging cells on one tentacle from firing when they come into contact with other tentacles or with the anemone’s body.
