Reproduction
Males mature at around 11 years of age, growing to 80 - 100 cm in length; females mature in 18–21 years and are slightly larger than males, reaching 98.5 - 159 cm. Both sexes are greyish brown in color and are countershaded. Males are identified by a pair of pelvic fins modified as sperm-transfer organs, or "claspers". The male inserts one clasper into the female cloaca during copulation.

Reproduction is aplacental viviparous, which was once called ovoviviparity. Fertilization usually takes place during the winter months and is internal. The male inserts one clasper into the female oviduct orifice and injects sperm along a groove on the clasper's dorsal section. Immediately following fertilization, the eggs are surrounded by thin shells called "candles" with one candle usually surrounding several eggs. Mating takes place in the winter months with gestation lasting 22–24 months. Litters range between two and eleven, but average six or seven.
