that doesn't have only one cause. They may run fast, but invertebrate nerve fibers lack a myelin sheath so the transmitting is slow. by the way they don't have a brain

Yeah, true...just like estafet. sooo many of them and depending on windspeed...
You know..I think it's kinda like comparing a race between a rabbit with a thousand turtles....
Q: Why are chemists great for solving problems?
A: They have all the solutions.
Yeah, if distance is not taken into consideration the flea would be the fastest by far.
As for fish... it's too hard to say with any real certianty because there are too many variables and they are constantly changing. Plus the ocean is just too under researched to provide any concrete data.
How would you put a falcon in a controlled environment for its diving speed?
They dive way faster then a Cheetah moves.
The previous posters are right though. Comparing the speed to size is the question. The flea's bodylengths per second is far greater then a cheetah's.
If you have say, a 5 ft. cheetah, (Yes, that'd include part of the tail). Then for it to travel at 35 bodylengths (175 ft.) a second, it would need to run at ~120 mph. Which it can't. And a flea definately jumps over 35 times its BL a second.
'Spittle' bugs are even better then fleas. They accelerate into a jump at over 400x the force of gravity. But fleas, only 130+. They are darn fine jumpers.

They do have a brain. Also, thats not the reason they go blind. Its because they run so fast they dont gather enough photons reflected from the prey to produce the continuous image.
i am having a hard time believing that, as we know light moves extremely fast. maybe their eyes are slower...
insects have continously fusing nervous crowdings, not a brain per se. i don't agree with calling it a brain because of the high degree of independence the rest of the body has from the "brain"
has anyone mentioned the pronghorn?
its max speed is 100 km/hr, which is decent, but it can sustain a speed of 65 km/hr for up to to 10 minutes.
as for the slowest animal, maybe Porifera?
Give me a place to stand, and I will move the Earth.
slowest animal? the ones that don't move. porifera, some clams, mussels etc
