Tiny blennies such as this spinyhead poke out from the coral in Cuba's Cayo Largo, always on the lookout for edible items within darting reach. "They are no bigger than an infant's finger, but they are tigers—extremely aggressive and territorial," says photographer David Doubilet. "They seem to have no concept of their own size."
