Hi,
O.K., the fastest animal in the air is a Peregrine Falcon (400km/h in a dive), a Cheeteh on the ground (~100 km/h), and I am not 100% sure on the water front but I believe it's a marlin or close relative of it(the ones with the looooong pointy nose and "sail" on their back).
I think that's it, but if I'm wrong then anyone please correct me.
