Trapezia tigrina is a species of guard crab in the family Trapeziidae.[2] The species was described in 1842 by Joseph Fortuné Théodore Eydoux and Louis François Auguste Souleyet.[1] A common name for the species is red-spotted guard crab.[3] It is known for its symbiotic relationship with corals, and can be distinguished by its vibrant red spots and flattened body.[4]
Description
The red-spotted guard crab's exoskeleton can range between cream and pink and can be spotted with up to 150 red spots.[5] It has 6 small teeth between its eyes, and the lower half of its pincers is smooth.[6] The red-spotted guard crab can grow between 1.5 and 2.5 cm (0.6 and 1.0 in)[7] and has a carapace width of up to 1.5 cm (0.6 in).[5] Reproduction is sexual, but sperm transfer is indirect.[6] It usually lives in solitude or in small groups, and mating often involves courtship rituals.[6]
Distribution and habitat
This coral-associated crab is native to the Indo-Pacific, including Hawai'i,[4] East Africa, the Red Sea, Japan,[6] Indonesia,[5] and the Philippines.[1] It inhabits shallow coral reefs between branching corals, where it develops a mutualistic relationship by defending the coral from predators in exchange for shelter.[5] Trapezia tigrina can be found at a depth between 1 and 90 m (3.3 and 295.3 ft).[6]
