The Large Flattened Anemone, scientifically known as Cryptodendrum adhaesivum, is a striking and captivating species of sea anemone. This anemone’s distinctive flattened form and vibrant coloration make it a fascinating sight in its natural habitat.
Description & Characteristics
Cryptodendrum adhaesivum is characterized by its flattened, disc-like body, often reaching a considerable size. Its surface is typically covered in numerous tentacles, which are arranged in a radial pattern around the central mouth. These tentacles are typically short and stubby, giving the anemone a somewhat “furry” appearance.
Habitat and Occurrence
Cryptodendrum adhaesivum is typically found in shallow, tropical waters, often inhabiting coral reefs and rocky areas. It prefers clear, well-lit environments, as it relies on the symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. These symbiotic algae provide the anemone with energy through photosynthesis, making them an integral part of the anemone’s survival. The Large Flattened Anemone’s habitat preference typically falls within the neritic zone, the marine zone extending from the low tide mark to the edge of the continental shelf.
Taxonomy
Cryptodendrum adhaesivum belongs to the Class Hexacorallia, an extensive group of marine invertebrates characterized by their six-fold symmetry. Within this class, it is further classified into the Order Actiniaria, which encompasses a diverse array of sea anemones. Finally, it is placed within the Family Thalassianthidae, a family of anemones that exhibit a flattened, disc-like morphology. This taxonomic classification reflects the evolutionary relationships and shared characteristics among these marine organisms.
Feeding
Cryptodendrum adhaesivum is carnivorous, feeding primarily on small fish, crustaceans, and other invertebrates that come within reach of its tentacles. It paralyzes its prey with stinging nematocysts, located within the tentacles. These nematocysts are specialized stinging cells that inject toxins into the prey, effectively immobilizing it. The Large Flattened Anemone has also been observed consuming clam meat, coralfish of all kinds, smelts, and even occasionally plankton. This diverse diet reflects its opportunistic nature, making it a successful predator in its marine environment.
