Frequently Asked Questions
Why can't a cheetah run at top speed for very long?
Sprinting at top speed generates a large amount of heat in its muscles almost instantly, so a cheetah can typically only sustain a full sprint for about 30 seconds or less.
Does the immortal jellyfish really live forever?
It can avoid death from aging, but it can still die from other causes, like being eaten by a predator or falling ill β so it isn't truly immortal in every sense.
