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). By the time the sharks reach adulthood, their growth rate slows to a more modest  per year.
