About forty years ago animal rights protesters put an end to the baby seal hunt that occurred every winter off the coast of New England. The seal population increased. The sharks noticed and expanded their hunting grounds. Nature abhors a vacuum.Try not to look like a seal if you really need to swim off Cape Cod.
I haven’t dove much since I sold my sail boat. But in SCUBA
class we were always taught to try not look like a seal floating on the surface. Get down to the bottom as soon as possible. Sharks look up for food for the most part. I used to dive in areas frequented by Orcas also. Although I think Orcas are a lot smarter than a shark.
Never look like a Seal.
