The Hotlips Spider Crab, scientifically known as Achaeopsis spinulosa, is a fascinating marine crustacean. This crab species is characterized by its distinctive appearance and its intriguing ecological role within its habitat.
Description and Characteristics
Achaeopsis spinulosa is a true spider crab, exhibiting the long, spindly legs that define this group. The crab’s carapace, or shell, can reach a maximum size of 3.9 inches (10 centimeters) in width. The species is readily identifiable by its bright orange to red coloration, often displaying a mottled pattern. The name “Hotlips” stems from the prominent, bright red, fleshy projections that extend from the crab’s mouthparts. These are believed to be sensory appendages, playing a role in its perception of the environment.
Habitat and Occurrence
The Hotlips Spider Crab primarily inhabits shallow, coastal waters, typically found in depths ranging from the intertidal zone to depths of around 100 meters (330 feet). Achaeopsis spinulosa is a common inhabitant of rocky reefs and seagrass beds, demonstrating a preference for these specific marine environments.
Taxonomy
Achaeopsis spinulosa belongs to the vast and diverse Class Malacostraca, which encompasses a wide range of crustaceans. Within this class, it is further classified under the Order Decapoda, a group that includes crabs, lobsters, and shrimp. Specifically, it falls into the Family Inachidae, a family known for its spider-like crabs, hence its common name.
