While shark attacks in Orange County waters are rare, it's hard not to worry about some great leviathan rearing its head and swallowing you whole while you wait for the next wave. On days when you're feeling too unlucky to surf, it's good to know the county's coastline is peppered with tidepools, those fertile rocky refuges for some of the sea's smaller creatures, where you can get your dose of ocean recreation without feeling overwhelmed by Mother Nature's top predators. Should you start to feel too intimidated by the grand scheme of things, find a sea anemone and run your finger along one of its wavy tentacles. Feel that stickiness? That's the anemone's attempt to paralyze and eat you. But you're too big and strong to be bested by that puny little animal. The knowledge that your finger is being bombarded with a dose of poison that would incapacitate a smaller organism is pretty empowering. Makes you feel good about being human . . . for once.
