The gulper shark, Centrophorus granulosus, is a deep-water shark that reproduces through aplacental viviparity. A total of 43 specimens caught with bottom long lines off the island of Crete between 350-480 m depth were examined. The samples consisted of 16 females and 27 males, ranging from 600 to 950 mm in total length and from 2000 to 4650 g in weight. Length-weight relationships were recorded. Most of the specimens were mature with high gonadosomatic indices (females: 0.1-8.9; males 0.1-2.2). The unique gravid female found had only one large, candle ovum in its right uterus. The analysis of the stomach contents revealed that the gulper shark is a voracious species that feeds mainly on fish (63.9%) and cephalopods (36.1%).
