frog

water and land dwelling (amphibious) creature known for being green, having long hind legs for jumping, and eating bugs by flipping out its sticky tongue at them. the tongue of a frog is backwards compared to a human's; it is hinged toward the front of the mouth so it can lash out to get bugs. when on land they breathe through their skin. frogs are a popular choice for dissection because while they aren't as accurate to the human anatomy as monkeys are, they are much cheaper. they are raised expressly for dissection, unlike cow eyes and fetal pigs, both of which are byproducts of the meat industry.
