Their bodies are made up of an adhesive pedal disk, a cylindrical body and an array of tentacles around a central mouth. Their tentacles are easily triggered, ready to inject a paralyzing neurotoxin into victims. They vary in colour and size, ranging from two cm to nearly two metres across.

There are over 1000 sea anemone species found throughout the world’s oceans at varying depths, although the largest occur in coastal tropical waters.
Diet:
Sea anemones are carnivorous.
Threats:
Some threats that sea anemones face are pollution, overcollection etc.
Can live up to 50 years or more.
When in danger some species can move and or swim away.
