they swim fast because that's how they are!
Turtles are generally slow movers, with their top speed varying depending on the species. On land, they may move at a pace of around 0.17 miles per hour (0.27 km/h), while some aquatic turtles can swim faster, reaching speeds up to 20 miles per hour (32 km/h).
Slow if not under threat.
Tortoises are slow, but turtles (which swim in fresh water or salt water) are actually quite fast. Tortoises are so slow because mainly of the heavy shell they carry on their back. In addition, not known to many people, their legs are naturally spread apart, so that also provides difficulty to walking, and slows it down considerably. Turtles are fast because their shell is flat (unlike the dome shell of a tortoise), and they have webbed feet with powerful muscles to help them swim. They are usually slow when on land, but fast when in water.
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.
A tiger can move extremely fast on ground, this in an advantage when hunting for prey,
Turtles are stereotyped as moving slow, but it really depends on the circumstance. They are capable of short bursts of speed on land, and in water they can swim very fast.
Well actually, turtles move slow not fast.. unless you are not worrying about it then it will seem like it's moving fast... but in further notice they move faster in water.
A person that is not slow, might be fast. Not slow means that a person does not move at a really slow pace. It means that they move at a moderate pace or above.
of course they are fast
Hummingbirds are really fast. They are very agile, as they can move with a very great ease
