You know that feeling of anticipation you get during a full moon that makes you want to go out and party? Well, maybe that's just me, but studies show that the "Full Moon Effect" touches other species, too. Not only are those werewolves on the hunt during full moons, but so are sharks, seals, and sea birds.
Since sea birds — like the streaked shearwater — rest on the water's surface, they are especially noticeable on a night with a full moon, where the light penetrating the water is brighter, and the birds cast a shadow below. So the sharks and seals that prey on the birds have a better chance of catching a midnight snack on those evenings. How did researchers first discover this activity? To find out, just read more.
Scientists first recorded this phenomenon when they noticed the shearwater birds were more active during full moons. The birds rested on the surface of the water for shorter periods of time, as they tried not to become dinner for a shark from under the surface. See? I'm not the only one on the prowl during those full moons!
