Trapezia intermedia is a species of crab that belongs to the family Trapeziidae. It is a common inhabitant of coral reefs, particularly in the Indo-Pacific region. This crab is known for its striking coloration and its symbiotic relationship with corals.
Description & Characteristics
Trapezia intermedia is a relatively small crab, with a carapace width typically reaching up to 25 millimeters. Its carapace is generally reddish-brown to orange in color, often with white or yellow spots. The crab’s claws are prominent, and they are often used to defend its territory or to collect food.
Habitat and Occurrence
Trapezia intermedia is a coral-dwelling species, commonly found in the Indo-Pacific region. This crab exhibits a preference for branching corals, particularly the genus Acropora, where it establishes its territory. It is often found in the intertidal zone and shallow reef environments, typically at depths ranging from a few meters to about 20 meters. This species is a resident of the tropical marine zone, thriving in warm, clear waters.
Taxonomy
Trapezia intermedia is classified within the phylum Arthropoda, belonging to the Class: Malacostraca, Order: Decapoda, and Family: Trapeziidae. This taxonomic classification places it among the group of crustaceans, specifically within the decapod crustaceans, which are characterized by having ten legs. Trapezia intermedia is a member of the family Trapeziidae, a group of crabs that are known for their symbiotic relationships with corals.
Feeding
Trapezia intermedia is an omnivore, feeding on a variety of food sources. Its diet primarily consists of algae and small invertebrates, such as plankton and small crustaceans. The crab’s diet is complemented by the symbiotic relationship it has with its host coral. Trapezia intermedia helps protect the coral from predators, while the coral provides the crab with a safe and stable habitat, along with a steady supply of food in the form of algae and other organisms that grow on the coral surface.
