Shark hatch report - Day 361

    About Shark Eggs


    It's a word that strikes fear into swimmers, but most sharks are totally harmless. Their eggs typically hatch inside the mother’s body, but the ones featured on the show are oviparous – meaning they hatch in the water.

    The eggs of the bamboo shark are normally deposited in shallow coastal seas, protected by an egg case. Embryos develop for 5–12 months, depending on the sea temperature. The warmer the water, the quicker they hatch. Estimates of the number of eggs laid ranges from nine to 41. The baby sharks are between 9-16cm long at birth, and have a lifespan of around 20 years.

    Vital Stats


    Fewer than six people on average are killed each year in unprovoked shark attacks. Substantially more humans are killed by cows.
