Why do sharks have so many teeth?
Open wide and count: a single shark might grow twenty thousand teeth in its lifetime. Twenty thousand! That's enough to fill a bathtub. Why does a shark need so many teeth when you and I get by with just thirty-two?
Start with what shark teeth are made for: grabbing and tearing, not chewing. A shark bites down once — hard — and shakes its head to rip away a chunk of prey. No grinding, no careful nibbling. Just raw tearing force.
