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.
The bird-voiced treefrog (Hyla avivoca) is a relatively small, tree-dwelling amphibian which is named for its distinctive, bird-like call. Given by the male, this call consists of a series of high-pitched, whistled â whit, whit, whit â notes, which are repeated several times. The bird-voiced treefrog inhabits forested swamps and wetlands and spends most of its time in the trees. 2  The bird-voiced treefrog uses its limbs to wipe a layer of mucous over its body, which helps to prevent it drying out.
