 These small fish, called bluehead chubs, pick up pebbles in their mouths to make gravel mounds that they use to lay eggs. Leslie snorkels as part of her job in habitat conservation, but for her, it's not just about science. To me, putting my head under the water is just this really peaceful experience. I'm only there. I'm only in that moment. Of course, snorkeling these waters is a lot different than a dive at your favorite coral reef.
