Eating jellyfish could protect endangered sea life. Researchers studied fishing around the world. They found fishing caught over 100 endangered species. This is not illegal because the fish are not protected. A researcher said: "We actively fish for many of these threatened species."

Jellyfish could become common on menus. Jellyfish are more sustainable than other sea life. A researcher said other seafood is not sustainable. She said we should fish for species that can survive the fishing pressure. She added: "We just have to care about weird-looking squishy things like sea cucumbers."
