How long does it take for a lemon shark to give birth?
Embryos develop inside the mother for up to 12 months until the female seeks shelter in a shallow nursery during spring or summer to give birth. A litter of lemon sharks may be as large as 17 pups. Pups remain in the nursery for several years, sheltered from larger predators, and feed on nutrients from nearby mangroves.
