My father knew a lot about invertebrate marine zoology and loved tidepools and everything that lived in or near them. My family went to a lot of places where we could dig clams, catch crabs, and identify all sorts of things from east coastal Canada to Florida. One vacation in about 1960 was to the recently opened Virgin Island Nat. Park where we camped at Hawksnest Bay (long since closed to camping). The reef came right to the shore. We spent hours in the water each day snorkeling over the reef, only inches to a few feet below us. I saw a green moray under a dead brain coral right at the tide line in 1 ft of water and 2-3 ft from shore and a bunch of squid out at the edge of the reef, plus many other unidentifiable (then) fish in between. One day, a woman also snorkeling put her hand on a long spined urchin and took a real hit. She was lucky. My father was a surgeon and had come medically prepared for all sorts of modest medical emergencies, including minor surgery to remove the 30-40 spines broken off in her hand. My father also was a member of the Audubon Society and a birder who got my brother and me interested in that. The combination of all these things just naturally led to a desire to dive. The diving didn't happen until after college, graduate school, marriage, kids and FINALLY, kids out of the house. Then, my wife and I got certified. Finally. Every time we dive, we comment about how my parents would have loved it, too.
