It depends on how fast of a swimmer you are.
Of course he is
Well
Skimmer (bird)
it depends how fast the swimmer is
as a baby no, but once it grows it will be
Your question is confusing. To quote Niels Bohr, "I'm a physicist, not a lumberjack!"
Absolutely not. Considering it was not made to swim, you can imagine that an animal that was born to swim, such as a dolphin, is much faster. In the water, hydrodynamics have a LOT to do with how fast an animal is. Which would travel faster, a big ball like an elephant, or a dart, like a dolphin? Assuming their general nature and hydrodynamics come into play, an elephant is far from being the fastest swimmer.
yes. they have to be to get away from other anamals to not get killed...
Yes they are according to all of the sites i have looked at! : )
This is an opinion, but I've always liked Natalie Coughlin as a swimmer. Her technique is great and her times are fast, too.
