They will replace teeth that are broken and young sharks can even replace their teeth weekly. [3] Although sharks constantly shed their teeth, factors such as water temperature affect the turnover rate. While warmer water temperatures produced faster rates, cold water temperatures slowed tooth replacement rates in nurse sharks. [4]
The variations usually lie in the morphology, number, development timeline, and types of teeth. [8] However, some mammals' teeth do develop differently than humans'. In mice, WNT signals are required for the initiation of tooth development. [9] [10] Rodents' teeth continually grow, forcing them to wear down their teeth by gnawing on various ...
Shark teeth are strong and made of enamel. Many sharks have 3 rows of teeth. These teeth are embedded in the gums, not the jaw. [10] Sharks are born with teeth that are constantly being replaced. Teeth are replaced every two weeks, approximately. [10] The shape of the teeth determine the diet of the shark.

We did a marine biology homeschool unit, where we focused on the good things sharks do for the environment. Summer camps where they learned to surf and practice ocean safety became the norm.
Great whites possess large, dagger-like teeth; basking shark teeth are much smaller 5–6 mm (0.20–0.24 in) and hooked; only the first three or four rows of the upper jaw and six or seven rows of the lower jaw function. In behaviour, the great white is an active predator of large animals, not a filter feeder.
Sharks are hunted for their meat, skin, cartilage, fins, livers, and teeth. While sharks sit near the top of the food chain in the ocean, their extinction would still have an effect on our life.
The gill openings are very small for the species' great size. Female Greenland sharks are typically larger than males. [13] Coloration can range from pale creamy-gray to blackish-brown and the body is typically uniform in color, though whitish spots or faint dark streaks are occasionally seen on the back. [11]
