Such species have long teeth that are pointed and highly curved. “Let the ocean do the hard work of sorting for you,” he says.

It occurs throughout the Indian Ocean, from South Africa, Madagascar, and Tanzania in the west to the Maldives and the Southwest Indian Ridge in the east. Coloration also appears to vary by region, with some individuals from the Mediterranean displaying a patchy, "piebald" pattern.
Gale family fossil finds from Topsail Beach, North Carolina, ranging from 11,000 to 75 million years old. Sand tiger sharks are hunted for preserving its tooth in aquariums and also for the purpose of analyzing the components of its teeth. Whereas shells feel thin and fragile, mineralized teeth are very sturdy, and this denser material can help you differentiate from oysters or shells.
