Red Spotted Coral Crab Sheltering in Pocillopora Coral Matrix in Bali

A macro underwater photograph captures a red spotted coral crab (Trapezia tigrina, also known as the pink spotted coral crab or leopard coral crab) tucked deeply within the protective branches of a hard coral colony (Pocillopora species) in Bali. The obligate coral-dwelling crustacean displays its iconic vivid pinkish-red carapace covered in a dense grid of fine dark spots, paired with smooth, yellowish-orange chelipeds and legs. Raised inside a narrow crevice between the coral polyps, the crab extends one claw upward, demonstrating its territorial defense and symbiotic lifestyle within live coral heads. The shallow depth of field frames the subject sharply while softly blurring the surrounding golden-brown coral corallites and dark interior shadow. Ideal for crustacean symbiosis research, marine invertebrate guidebooks, coral reef ecology features, and professional nature stock media.
