For a 140-pound leopard whiptail ray (Himantura undulata) living at the New England Aquarium in Boston, it’s a whole other animal. Bringing such a large ray from its habitat into an exam pool takes at least eight people. During the ray’s check-up, the aquarists focus on collecting the fish from their exhibit and bringing it into the exam pool. The two leopard whiptail rays eat 2.5 pounds of food every day.
