What if there were no sharks?

7 years ago
Sharks are magnificent predators that represent an impressive evolutionary success story. They've swum the oceans for more than 400 million years, diversifying over time to inhabit rivers and lakes as well. About 500 known species are alive today, and there are likely even more yet to be discovered.
