The coconut crab, il più grande artropode terrestre del mondo

The coconut crab (Birgus latro Linnaeus 1767) is the largest terrestrial arthropod in the world.

land hermit crab is a famous for his ability to crack coconuts with its strong claws to eat the contents. It is sometimes chiamato "granchio ladro" (in inglese robber crab) o "ladro delle palme" (in tedesco Palmendieb), perché alcuni granchi del cocco rubano oggetti luccicanti come padelle ed argenteria da case e tende.

È anche noto come terrestrial hermit crab ("paguro terrestre"), a causa dell'uso di conchiglie da parte dei giovani individui (tuttavia il termine paguro terrestre si applica anche ad altri paguri terrestri, come per esempio il paguro terrestre australiano Coenobita variabilis). Il granchio del cocco ha differenti nomi locali, come, ad esempio, ayuyu a Guam, unga o kaveu.

Gli esemplari di questa specie giungono in media fino ai 4 kg di peso, 400 mm di lunghezza del corpo, un metro di apertura legs, with males generally larger than females (sexual dimorphism). Some authors have described specimens weighing up to more than 17 kg and a body length of 1 m. It is believed that this is near the theoretical limit for a terrestrial arthropod. However, when the body is supported by water, larger sizes are possible (see, for example, the Japanese spider crab Macrocheira kaempferi). They can reach an age of 30-60 years.
