Shark Yoga Mats
If you are walking on a beach, you might find a shark tooth as some sharks lose up to 30,000 teeth during their lifetimes. Their teeth constantly move forward in their mouth, like they were on a conveyor belt. Most sharks lose their teeth one at a time while other shark species, like cookiecutter sharks, lose entire rows of teeth simultaneously. If you are fascinated by sharks, use a shark yoga mat.
