Great Hammerhead shark tooth size

Another commonly asked question is what is the exact tooth size of Great Hammerhead sharks? Allow us to tell you more in this regard.

Great Hammerhead shark tooth color

One of the most frequently asked questions about shark teeth pertains to its color. Let us learn what color teeth do Great Hammerheads have.

The Great Hammerhead sharks, like most other shark varieties, have white or cream-colored teeth. Since sharks lose their teeth often, the tooth sinks to the bottom of the ocean and gets buried under sediment. Here, the tooth undergoes the process of fossilization over time and acquires a dark hue. 

Most shark teeth found around river beds and in sandpits are dark-colored because they have been fossilized. Sometimes, the color of the fossilized shark tooth may even be tan or beige. 

Great Hammerhead shark tooth shape

Great Hammerheads typically have triangular teeth. One interesting fact about their teeth set is that they are usually unserrated, and the shape varies along the jaw. Some hammerhead varieties (like the smooth hammerhead shark) have homodont teeth, which are all relatively smaller and of the same size. 

Since hammerhead sharks primarily feed on fish, squid, and other animals, not having serrated teeth isn’t a disadvantage and their small, sharp, and smooth teeth help them bite and chew their prey better.
