Jawaban Singkat
Sharks typically have 50 to 300 teeth at any given time, arranged in multiple rows. Over a lifetime, a shark may grow 20,000 to 30,000 teeth as they continuously replace lost ones.

Sharks have 5-15 rows of teeth with only the front 1-2 rows actively used for biting. Back rows are replacement teeth that move forward like a conveyor belt when front teeth fall out.

Shark Tooth Characteristics
Shark teeth are made of fluoride-coated enamel (naturally cavity-resistant), attached only to gums (not jaw bone), and vary by diet: serrated for cutting flesh, pointed for gripping fish, flat for crushing shells.
Pertanyaan yang Sering Diajukan
Mengapa sharks lose so many teeth?
Shark teeth aren't deeply rooted in bone like ours — they're embedded in gums and fall out easily during feeding. This is actually advantageous: damaged or worn teeth are quickly replaced with sharp new ones.
Apakah semua sharks have sharp teeth?
No. Whale sharks and basking sharks are filter feeders with tiny, almost useless teeth. Nurse sharks have flat crushing teeth for shellfish. Horn sharks have both pointed front teeth and flat back molars.
How fast do shark teeth grow back?
New teeth move into position within 24-48 hours after a tooth is lost. The replacement process is continuous — sharks have developing teeth in various stages throughout their jaw at all times.
Bisakah Anda tell a shark species from its teeth?
Yes! Each species has distinctive tooth shapes. Great whites have triangular serrated teeth, makos have thin pointed teeth, and tiger sharks have curved notched teeth. Paleontologists identify extinct sharks this way.
Berapa banyak is a shark tooth worth?
Common fossilized teeth: $1-25. Large great white teeth: $50-200. Rare megalodon teeth: $50-$50,000+ depending on size, condition, and color. The largest megalodon teeth exceed 7 inches!
