Sharks have persisted as powerful ocean predators for more than 400 million years. They survived five mass extinctions, diversifying into an amazing variety of forms and lifestyles. But this ancient lineage is now among the world’s most threatened species groups due to overexploitation in poorly regulated fisheries and the proliferation of wasteful finning practices.

The yellowfin tuna commonly enjoyed in sashimi, poke bowls and salad sandwiches may soon disappear from these dishes if current overexploitation rates remain unchanged, especially in the Indian Ocean.
