How long is a newborn shark?
At birth a baby great white shark is already about 5 feet (1.5 meters) long; as it grows it may reach a length up to four times that. The pup (which is what a baby shark is called) will live its life at the top of the ocean’s food chain.
How many babies do sharks have at one time?

What do baby sharks eat when they are born?

Do sharks get cavities?
Sharks can’t get cavities. It takes around 10,000 years for a shark’s tooth to fossilize. The most commonly found shark tooth fossils are from around 65,000 years ago!
Why do sharks never get cavities?
1. Even if sharks could brush their teeth, they wouldn’t need to: Shark teeth are covered in fluoride, making them cavity-resistant. One 2012 study published in the Journal of Structural Biology found that sharks’ enamel is made up of a chemical called fluoroapatite, which is resistant to acid produced by bacteria.
Do baby sharks lose their teeth?
Some sharks can lose their teeth in as little as a week. Unlike humans, sharks can easily replace their lost teeth with new ones. They can be self-conscious when they talk with a missing tooth so they have to find a way to replace them as fast as possible.
What to do if child has shark teeth?
The way you handle shark teeth depends on the baby tooth. If it’s even a little loose, have your child try to wiggle it several times a day to further loosen it. In many of these cases, the baby tooth will eventually fall out on its own, and the permanent tooth will move into place.
When should I worry about my childs shark teeth?
Fortunately, shark teeth are not dangerous and are not something you need to be too worried about. In many cases, the tooth will get loose as the permanent tooth comes in. Many children will start to wiggle the tooth on their own. If they can wiggle it out, then the problem can be resolved without intervention.
