The Pink-spotted Bead Anemone, scientifically known as Anthopleura buddemeieri, is a fascinating marine invertebrate belonging to the family Actiniidae. This anemone is known for its vibrant coloration and unique bead-like appearance, making it a captivating sight in its natural habitat.
Description & Characteristics
The Anthopleura buddemeieri is characterized by its distinctive pink or reddish-brown body, often adorned with white or cream-colored spots. The spots resemble beads, giving rise to the common name of the species. The anemone’s body is typically cylindrical in shape and can reach a maximum size of approximately 2 inches in diameter. Its oral disc is surrounded by numerous tentacles, which are used for capturing prey and for defense.
Habitat and Occurrence
The Pink-spotted Bead Anemone is found primarily in the Supralitoral zone, which is the area above the high tide mark. This zone is characterized by its exposure to air and salt spray, making it a challenging environment for most marine organisms. However, Anthopleura buddemeieri has adapted to these conditions and is able to survive periods of desiccation.
This species is commonly found attached to rocks, shells, and other hard substrates in the intertidal zone. They are often found in aggregations, with multiple individuals clustered together.
Taxonomy
The Pink-spotted Bead Anemone is classified under the Phylum Cnidaria, which includes other fascinating marine organisms like jellyfish and corals. Within this phylum, Anthopleura buddemeieri belongs to the Class: Hexacorallia, Order: Actiniaria, and Family: Actiniidae. This classification reflects the species’ evolutionary relationship with other anemones and its distinct anatomical characteristics.
Feeding
The Anthopleura buddemeieri is an azooxanthellat, meaning that it does not contain photosynthetic algae within its tissues. As a result, it is nonphotosynthetic and relies entirely on capturing prey for sustenance. Its diet consists primarily of small invertebrates, including zooplankton, which it captures using its stinging tentacles.
