Snorkeling for collecting in super shallow water and near inshore rocks, can collect most fish and crustaceans as well as starfish and the like, nothing that is hard and attached to the bottom. Will need to finish collecting 2 days before I return home to allow the animals to purge to avoid ammonia buildup and then either check or carry on on the plane, both are options now though checking is easier. Can only colect 5 organisms per day though if I bring any back it will be much less than that.
