You get out there and learn for the rest of us! I just heard about some shark sanctuaries that have been designated in some Asian countries to help keep the populations up--or bring them back. The overwhelming demand for shark fins in that region has really been depleting shark populations. I wonder if we see any of those effects here in US waters, too? I don't know much about shark migratory habits, so I'd be interested in knowing if dwindling populations in Asia equal dwindling populations in our area of the world.
Look forward to hearing from you!
