Hermit crab increased prevalence of marine debris, but also due to depletion of seashells from beaches due to humans collecting them. Hermit crab species range in size and shape, from species with a carapace only a few millimetres long to "Coenobita brevimanus", which can live 12–70 years and can approach the size of a coconut. The shell-less hermit crab "Birgus latro" (coconut crab) is the world's largest terrestrial invertebrate. The young develop in stages, with the first two (the nauplius and protozoea) occurring inside the egg. Most hermit crab larvae hatch at the third stage, the zoea. In this larval stage, the
Stripe-throated hermit been considered a subspecies of the little hermit ("P. longuemareus"), but morphological data suggest it may be closer to the grey-chinned hermit ("P. griseolaris"). At present most, if not all, major authorities accept the split (SACC, the Clements check list, the Howard & Moore check list, etc.). It has been suggested that the mainly Central American taxon "saturatus", which typically is considered a subspecies of "P. striigularis", may deserve species status, in which case it would become the dusky hermit or Boucard's hermit ("P. saturatus"). The taxon "adolphi" is considered a junior synonym of "saturatus" by most authorities. It occurs
