There was plenty going on at 60 feet. Jim swam along enjoying the action and watching Chad, who was aiming his underwater camera at everything that moved—a big barracuda with its razor teeth gleaming, an octopus crouching near a clump of elkhorn coral, a reef shark nosing around not far away. Jim could believe what he’d heard about there being some 600 kinds of fish in these waters. His thoughts broke off as he spotted a huge green moray eel some distance from them. It had to be six feet long. Jim saw his cousin squaring up to take a photograph, but before Chad could get his shot, the big eel began to swim away. Jim could practically read Chad’s thoughts—Oh, no, you don’t—as he took off after the moray. Jim followed in time to see the eel slither into a large, cave-like formation of rocks and coral that lay on the ocean floor. Surely Chad wasn’t going to follow the moray? Yes, he was! Chad was heading right toward the opening of the undersea cave. By the time Jim had caught up to him, his cousin had disappeared into the cave. What to do now? Jim glanced at his watch and saw they still had 20 minutes of air left. If he didn’t follow Chad into the cave, he’d never hear the end of it, and anyway, he wanted to get another look at that huge moray. Without any more hesitation, Jim followed his cousin.
