How Crying Works. What happens when you cry, exactly? A salty fluid chock full of protein, water, mucus and oil is released from the lacrimal gland in the upper, outer region of your eye. This fluid, better known as tears, then flows down the surface of your eye, across your face and smears your mascara.
The American bullfrog (Rana catesbeiana), often simply known as the bullfrog in Canada and the United States, is an aquatic frog, a member of the family Ranidae, or âtrue frogsâ. This frog has an olive green back and sides blotched with brownish markings and a whitish belly spotted with yellow or grey.
Bullfrogs are predators that eat practically anything they can catch. They can swallow tree frogs, other amphibians and reptiles such as the western pond turtle, minnows, small birds, and young snakes. Introduced bullfrogs have been blamed for native species declines in much of North America.hey are found in a variety of freshwater habitats, including ponds, marshes, streams, rivers, canals, reservoirs, ditches, shallow wetlands, and storm water ponds. Bullfrogs compete with, and prey on, a wide range of native species, and can affect significantly native ecosystems such as wetlands.
