The term "Slow" is based on your perspective. From our perspective, turtles are slow because they move slower than we do and, indeed, even slower than other things their size. This is only true, however, on land. In the water they are actually very fast. For instance, a green turtle in the sea can reach nearly 20mph. So, the belief that turtles are slow is based on the perspective of a land creature, which turtles are for only brief periods of their life.
