The phylogeny of king crabs as hermit crabs who underwent secondary calcification and left their shell has been suspected since the late 1800s. [4] They are believed to have originated during the Early Miocene in shallow North Pacific waters, where most king crab genera – including all Hapalogastrinae – are distributed and where they exhibit a high amount of morphological diversity.
Domestication is a gradual process, so there is no precise moment in the history of a given species when it can be considered to have become fully domesticated. Zooarchaeology has identified three classes of animal domesticates: Pets (dogs, cats, ferrets, hamsters, etc.) Livestock (cattle, sheep, pigs, goats, etc.)
Maguimithrax spinosissimus, [2] also known as the Caribbean king crab, [3] West Indian spider crab, channel clinging crab, reef or spiny spider crab, and coral crab, is a species of spider crab that occurs throughout South Florida and across the Caribbean Islands.
The example of king crabs (family Lithodidae) evolving from hermit crabs has been particularly well studied, and evidence in their biology supports this theory. For example, most hermit crabs are asymmetrical , and fit well into spiral snail shells ; the abdomens of king crabs, even though they do not use snail shells for shelter, are also ...
