Самый крупный представитель членистоногих: кокосовый краб или пальмовый вор
The coconut crab(Birgus latro), is a species of terrestrial hermit crab, also known as the robber crab or palm thief. It is the largest land-living arthropod in the world, with a weight of up to 4.1 kg (9.0 lb). It is found on islands across the Indian Ocean and parts of the Pacific Ocean. Coconut crabs have evolved organs known as “branchiostegal lungs”, which are used instead of the vestigial gills for breathing. They cannot swim, and will drown if immersed in water for long.
The coconut crab, Birgus latro, is a species of terrestrial hermit crab, also known as the robber crab or palm thief. It is the largest land-living arthropod in the world. Like hermit crabs, juvenile coconut crabs use empty gastropod shells for protection, but the adults develop a tough exoskeleton on their abdomen and stop carrying a shell. The species is popularly associated with the coconut, and has been widely reported to climb trees to pick coconuts, which it then opens to eat the flesh.
Giant Hermit Crab
Giant Hermit Crab (Petrochirus diogenes), largest hermit crab in the Caribbean, growing to 5" to 8" long. Member of family Diogenidae, the Left-handed Hermit Crabs left claw is slightly larger than its right. The surface of its exoskeleton is patterned in a way that resembles irregular scales. They typically live in sandy areas or sea grass large shells, most commonly the Queen Conch. Photo taken at Creole Rock in St. Martin.
