The researchers attached cameras to the tiger sharks' fins.
The world's largest underwater forest of seagrass is what the sharks led them to, according to a new study.
Carlos Duarte from the King Abdullah University of Science and Technology in Saudi Arabia told The Guardian that the finding shows how far away we are from exploring the ocean.
Studies of seagrass are important in the fight against climate change because it can store a lot of carbon.
There's a lot we don't know about the large swathes of seagrass beneath the surface as they're difficult to see using aerial or satellite-based photography.
The team of researchers decided to send tiger sharks instead of human divers in order to save money and time. The expert divers are capable of covering large swathes of the sea.
Climate change is affecting the globe and marine life, and knowing where there's seagrass is important. It can cause a lot of carbon dioxide to be released into the atmosphere.
Seagrass is one of the best allies and assets that we have in terms of trying to mitigate the effects of climate change.
Other mammal species are being used to explore other corners of the ocean.
They are taking us to new places that we didn't know existed.
Scientists discovered the world's largest seagrass forest by filming sharks.
Scientists are interested in sharks that can walk on land for two hours.
