Sound

Like other spiny lobsters (with the exception of the genera '' Jasus'' and '' Projasus''), ''Palibythus'' is capable of making a loud screeching noise to distract or discourage potential

Relatives

''Palibythus'' was originally placed with '' Palinurellus'' in the family Synaxidae, on the basis that both genera possess a triangular

Fishery

Although ''Palibythus'' is a large enough lobster to provide food for human consumption, its rarity, and the depths at which it lives, seem to preclude any commercial
fishery Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life or, more commonly, the site where such enterprise takes place ( a.k.a., fishing grounds). Commercial fisheries include wild fisheries and fish far ...
