Strawberry Anemone (Actinia fragacea)

…a species of Actiniid sea anemone which is found in the northeastern and eastern Atlantic Ocean. Its range extends from Norway, Scotland and Ireland to the Mediterranean Sea and North Africa, including the Azores, the Canary Islands and Cape Verde. Strawberry anemones typically inhabit the intertidal and sublittoral zone at depths less than 10 meters (33 ft). They are generally found attached to rocks and boulders.

Beadlet anemone  (Tomate de mar)

Actinia equina (Actiniaria - Actiniidae), the Beadlet anemone, is a considerably versatile intertidal sea anemone, with a wide array of color variation, from green to red. The most common hue is rust-red.

In the beadlet anemone, the tentacles (up to 192) are arranged radially in six circles around the mouth (the opening to the gastrovascular cavity). Bright blue spots (shown in the photo), called acrorhagi, are below the tentacles on the outer margin of the column and look like warts.

This sea anemone is found primarily in the North Atlantic Ocean and the Mediterannean Sea, but populations also exist stretching down along Africa’s Atlantic coast.

Sea anemones are a group of water-dwelling, predatory animals of the order Actiniaria. There are more than 1,000 species of sea anemones found throughout the world’s oceans, many attached to rocks on the seafloor. Their bodies are composed of an adhesive pedal disk, a cylindrical body, and an array of tentacles. The tentacles are triggered by the slightest touch, firing a harpoon-like filament into their victim and injecting a paralyzing neurotoxin. 

Estefanía Rodríguez, Associate Curator of Invertebrate Zoology at the American Museum of Natural History is studying the fascinating varieties of anemones and other sea life in Antarctica. In 2014, Dr. Rodríguez discovered a giant anemone-like creature with tentacles reaching more than 6.5 feet long that actually belongs to an entirely new order of animals, demonstrating there is still much to be learned about polar marine life!
