Onespot Fringehead females lay a ton of eggs when breeding. How much is a ton? Try anywhere from 1,000 to 10,000 eggs. But you won’t believe where they lay their eggs. While Fringeheads often nest on the bottom of rocks or clam burrows, researchers have learned that they also nest in the oddest place of all—empty beer bottles that have somehow made their way to the ocean floor.
