Baby reef fishes take the gold
A study has shown that baby reef fishes clock in at 15 to 40 body lengths per second, making them one of the fastest youngsters around.
In contrast, baby herring swim up to two body lengths per second, while the fastest human (Olympic gold medallist Michael Phelps) manages just 1.4 body lengths per second.
So how did those tiny baby reef fishes get to be so fast so early in their lives?
