Turtles are definitely faster than snails. The average turtle is able to move 1.07 miles per hour on land and can swim even faster, while the garden snail can only move 0.03 miles per hour. In the case of answering this question it looks like Mr. Turtle is going to be waiting a really long time once he leaves Mr. Snail in the dust and reaches the finish line. Many people make the assumption that the snail is the slowest animal in the world; however the actual slowest animal in the world is the sloth.
