Sharks have been swimming our oceans since the age of the dinosaurs. But these amazing animals are dying out and fast, due to the high demand for their fins.
In fact, the environmental organization Oceana says up to 73 million sharks are killed every year. Many people consider the practice of finning to be very barbaric.
Fishermen actually hack off the shark's fins and throw it back into the sea alive. The shark then slowly starves to death, drowns or is eaten alive.
Environmental groups say poachers often enter protected areas to illegally slaughter sharks for their fins. One Costa Rican organization says enough is enough.
