The slowest animal is the sloth. Their top speed is 0.003 miles per hour. The fastest animal is the cheetah or the peregrine falcon (there is an ongoing debate about which one is faster). Cheetahs' top speed is 75 mph. Peregrine falcons' top speed is 60-100 mph. On land, the cheetah is the fastest. In the air, the peregrine falcon is the fastest. Hope that helped =)
If you ask about mamal... it should be a Dolphin.
The fastest sea animal is the sailfish (marlin), which can reach 120 km per hour. I dunno about the other 9.
