The White Stinging Anemone, scientifically known as Anthothoe chilensis, is a captivating marine invertebrate belonging to the phylum Cnidaria. This anemone, with its characteristic white coloration, is a common sight in various marine environments, adding vibrancy to the underwater landscape.
Description & Characteristics
The Anthothoe chilensis is distinguished by its white, cylindrical body, which can reach a maximum size of several centimeters in diameter. Its column, the main body part, is typically smooth and may have a slightly wrinkled texture. The anemone’s most striking feature is its oral disc, the upper surface, which is adorned with a central mouth surrounded by numerous tentacles. These tentacles, often numerous and arranged in rings around the mouth, are slender and possess stinging cells called nematocysts. These nematocysts are used to capture prey and defend against potential threats.
Habitat and Occurrence
The White Stinging Anemone thrives in a variety of marine environments, including the subtidal, sublittoral, infralittoral, and deep zones of the oceans. It is typically found from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. This wide distribution range places Anthothoe chilensis in the neritic zone, a marine environment encompassing the waters above the continental shelf.
Taxonomy
The White Stinging Anemone, Anthothoe chilensis, is classified within the phylum Cnidaria, a diverse group of aquatic animals known for their stinging cells. It belongs to the Class: Hexacorallia, which encompasses a wide range of corals and anemones, all characterized by their six-fold symmetry. Within this class, Anthothoe chilensis is further categorized into the Order: Actiniaria, a group of solitary anemones, and the Family: Sagartiidae, a family of sea anemones commonly found in a variety of marine environments.
Feeding
The White Stinging Anemone, like many other sea anemones, is a carnivore, primarily feeding on zooplankton. These tiny organisms, including small crustaceans and larval stages of various marine species, are captured using the anemone’s stinging tentacles. When prey comes into contact with the tentacles, the nematocysts release toxins that paralyze the prey, allowing the anemone to bring it to its mouth for consumption.
