Abstract

Some large Saurenchelys specimens collected from Daxi, Yilan, NE Taiwan, and Da Nang, Vietnam, by bottom trawl at depths of 100-200 m, are described as Saurenchelys gigas new species. They differ from all known adult Saurenchelys species by predorsal length 40.9-46.8, head length 36.8-39.3in % of preanal length, 38-40 preanal vertebrae, 63-70 precaudal vertebrae, 38-42 preanal lateral-line pores, 56-63 preanal dorsal fin rays, and larger size (the maximum size 1155 mm TL).
