 An important nursery area is believed to exist at the continental shelf break at 34°S latitude, near the southern extreme of this species' range.The newborn young measure long, and add around or 38% of their body length in their first year.This fast rate of growth serves to shorten the period immediately after birth when the small pups are most vulnerable to predators, a strategy similar to that employed by the silky shark ("C. falciformis").
