Pelia pacifica is a species of spider crab belonging to the family Epialtidae. It is a relatively common species found in the coastal waters of the Pacific Ocean.
Description & Characteristics
Pelia pacifica is characterized by its distinctive spiny carapace, long, slender legs, and a prominent rostrum. The carapace can grow to a maximum size of approximately 100 millimeters (4 inches) in width. The legs are covered in numerous spines and bristles, which help the crab to grip onto surfaces and capture prey.
Habitat and Occurrence
Pelia pacifica is typically found in shallow, coastal waters, often in rocky areas or kelp forests. It is commonly encountered in the intertidal zone, where it can be seen clinging to rocks or seaweed. The species is a prevalent presence in the neritic zone, which encompasses the shallow waters extending from the shoreline to the edge of the continental shelf. This marine zone provides a suitable environment for Pelia pacifica to thrive, offering ample resources and protection.
Taxonomy
Pelia pacifica belongs to the family Epialtidae, a group of spider crabs known for their elongated legs and spiny exoskeletons. The species is classified within the Class Malacostraca, which includes a wide range of crustaceans, and the Order Decapoda, which comprises ten-legged crustaceans, such as lobsters, shrimps, and crabs.
Feeding
Pelia pacifica is an opportunistic omnivore, feeding on a variety of organisms, including algae, small invertebrates, and decaying matter. It uses its long, spiny legs to capture prey and bring it to its mouth.
