Anemone

Actiniaria

A stinging sea animal disguised as a flower.

Sea Anemones may look like swaying flowers, but they are animal cousins of corals and jellyfish. Their tentacles fire microscopic stinging capsules that capture prey and discourage hungry visitors.

Tell-your-friends facts

Four wonderfully wild things

  1. 1

    Anemones have one body opening for both food and waste.

  2. 2

    A sticky foot anchors the body, but many can slowly glide to a new spot.

  3. 3

    Some host clownfish, shrimp, algae, or other helpful partners.

  4. 4

    They have no brain; a spread-out nerve net coordinates their movements.

Ocean superpower

Built to be amazing
