Q: The easiest way to tell the difference between crocodiles and alligators is to look at their snouts. Alligators have a wide, rounded, "U"-shaped snouts with larger noses, whereas crocodiles have longer, thinner, pointed "V"-shaped snouts and smaller noses. Alligator snouts are also shorter than crocodile snouts.  The broad snouts that alligators have give them more strength than crocodiles. They can crush hard shelled prey, such as turtles, much easier than crocodiles can. Crocodiles tend to eat more fish and mammals. The crocodile's upper and lower jaws are nearly the same width, so the teeth are exposed all along the jaw line in an interlocking pattern, even when the mouth is closed. An alligator, on the other hand, has a wider upper jaw, so when its mouth is closed the teeth in the lower jaw fit into sockets of the upper jaw, hidden from view. Only the teeth of the upper jaw are exposed along the lower jaw line.  Alligators' upper jaws are wider than their lower jaws, so the upper jaw overlaps the lower jaw. Because of this, the teeth in the lower jaw are hidden when their mouth closes. Crocodiles' upper and lower jaws are approximately the same width, so their upper and lower teeth interlock when their mouth shuts. This causes some of their teeth to show when their mouth closes. They'll almost look like they're smiling, as the fourth tooth on each side of the lower jaw sticks up over the upper lip. Alligators tend to have a darker skin than crocodiles do. Crocodiles normally have lighter skin, usually in the colours of olive green or brown. Alligators usually have darker, blackish-grey skin. Crocodiles are also longer than alligators. On average, full grown crocodiles are 5.8 meters, whereas full grown alligators are 3.4 meters.  On average, full grown alligators weigh 800-1,000lbs. Crocodiles can grow to be a bit larger and weight between 1,000-2,000lbs.  The average lifespan of alligators is 30-50 years, and the average lifespan of crocodiles is 70-100 years. Most crocodiles have a fringe type appearance on their hind legs and feet that alligators do not. Also, alligators have webbed feet, and crocodiles do not.
A: Look at the snout. Pay attention to the teeth. Observe their bodies. Look at the difference in their legs and feet.

Q: Add a pea-sized amount of toothpaste to your nail brush. Work the toothpaste into the brush bristles for a more even application.  Choose a whitening toothpaste. It’s okay to add more toothpaste if you want. Just as you did when you cleaned your nails with the brush, scrub under your nails to apply the toothpaste. Make sure that a thin layer of toothpaste remains under your nail. The toothpaste needs time for the whitening action to work. After the three minutes, wash the toothpaste from your fingernails. Squeeze the juice from two lemons, or use a container of lemon juice. Do not add water to your lemon juice.  You will just need enough lemon juice to soak your fingertips. You can find pre-squeezed lemon juice in the grocery store. Leave your fingertips in the bowl to give the lemon juice time to whiten your nails. After the ten minutes, rinse your hands in clean water. Pour two tablespoons (30 milliliters) of baking soda into a bowl. Add enough warm water to make a thick paste. If you accidentally put in too much water, it’s ok to add some more baking soda to thicken the paste. Smooth the paste under your fingernails. Allow it to sit for five minutes before washing it off with warm water. Use soap and water to clean away any remaining residue from the whitening treatments. After you dry your hands, apply a moisturizing hand cream.
