Beadlet Anemone

The Beadlet Anemone (Actinia equina) is a marine (saltwater) invertebrate in the Actiniidae family of anemones, which means that is has no backbone. It is also known as the Sea Tomato. It is an animal, not a plant. 

The Beadlet Anemone is bright red with tentacles, and its mouth in the centre. It has short, conical tentacles arranged in rows of six or more, which is called the crown of tentacles. The crown surrounds its oral disc (mouth). The tips of the tentacles can be pointed or blunt.

It grows up toabout 17 centimetres (7 inches) long. 

The Beadlet Anemone is native to the waters of the Mediterranean Sea and the North Sea. It prefers rocky areas along the coast.

It can move slowly, using its basal disc, but usually it is still, attached to a rock. Therefore, it is mostly sessile (not moving). 

It feeds on small fish and molluscs. It uses its stinging cells in its tentacles to protect itself from predators. Its main predators include sea stars (starfish) and sea snails.

It is solitary. 

The female lays eggs in the water. When they hatch into larvae, the larvae float and drift in the sea until fully grown. When they are fully grown adults, they become benthic – living on the bottom of the ocean.
