Trivial pursuit time! (which means you can't Google). How fast can land, sea, and air animals travel?

Haven’t had one of these for awhile. Trivia time! What are the fastest recorded animal locomotion times?

1)
Fastest mammal speed

2)
Fastest bird speed

3)
Fastest fish speed

I looked at the answers, so I won’t guess. But I will give one clue – the fish surprised me. Also, reptiles are sluggards, they are not included in the question. If you have to get somewhere FAST!, do not depend on a reptile.
