New ghost shark species Harriotta avia identified in New Zealand, differing from known species genetically and morphologically.

A new ghost shark species, Harriotta avia, has been identified off New Zealand's eastern coast. Notable for its long nose, which can measure half its body length, this species differs genetically and morphologically from previously known ghost sharks. It thrives at depths up to 2,600 meters, primarily feeding on crustaceans. The discovery challenges prior assumptions of a single global species and highlights the shark's elusive nature.
