It is found on or near the ocean floor, in the deep waters off New Caledonia and Vanuatu.

==Taxonomy==
The first specimens of ''G. priapus'' were collected in the 1990s, during a series of Indo-Pacific research cruises jointly undertaken by the Institut de recherche pour le développement (IRD) and the Muséum national d'histoire naturelle (MNHN). Bernard Séret and Peter Last described the new species in a 2008 volume of the scientific journal ''Zootaxa''. It was given the specific epithet ''priapus'' after the Greek fertility god Priapos, in reference to the distinctively long claspers of males. The type specimen is a long adult male trawled by the RV ''Alis'' off New Caledonia on March 30, 1994. Within the genus, this species most closely resembles the slender sawtail catshark (''G. gracilis'').
