Specimens of Squalus cubensis (n = 137; 38.5–67.3 cm total length–TL) and Squalus cf. quasimodo (n = 183; 41.1–93.2 cm TL) were opportunistically collected from the catches of artisanal gillnetters working in the southern Caribbean Sea off Venezuela between January 2006 and December 2007 and assessed for maturation and reproductive biology. Catches of each species comprised considerably more, and mostly larger, females (n = 124 and 174, for S. cubensis and S. cf. quasimodo, respectively) than males (n = 13 and 9). Based on changes to the reproductive organs, both species were partitioned into four maturation stages for females (juvenile, ovulating, gravid and post-partum) and two stages for males (juvenile and adult). Squalus cubensis and S. cf. quasimodo both were least represented by juveniles (n = 10 and 13, respectively) and most by ovulating females (n = 74 and 120, respectively). Formal assessments of 50% sizes at sexual maturity (± SE) were restricted to females, and were 44.5 ± 0.5 TL for S. cubensis and 59.9 ± 0.2 cm TL for S. cf. quasimodo. All sampled male S. cubensis were mature above 43.8 cm TL, while only one adult male S. cf. quasimodo (82.4 cm TL) was recorded. Gravid females
