King crabs are generally thought to be derived from hermit crab-like ancestors, which may explain the asymmetry still found in the adult forms. This ancestry is supported by several anatomical peculiarities which are present only in king crabs and hermit crabs. Although some doubt still
Coastal peacock spider Coastal peacock spider Maratus speciosus, sometimes called the coastal peacock spider, is an Australian species of jumping spider (family Salticidae). They are only known to inhabit the vegetation of the coastal sand dunes of southwestern Western Australia.
