Actinia equina

Actinia equina, commonly known as the beadlet sea anemone, is a marine animal found in rocky coastal waters, particularly in Europe. It has a cylindrical body and can be recognized by its vibrant colors and a crown of tentacles that it uses to capture prey, such as small fish and plankton. When disturbed, it can retract its tentacles and contract its body to protect itself. Beadlet sea anemones are known to adhere to rocks and can tolerate varying salinity levels, making them resilient in their habitats. They play an essential role in their ecosystem by providing food and habitat for other marine organisms.
