Vast seagrass forest is discovered by strapping cameras to sharks, and extend the area of seagrass by more than 40%

Tiger sharks are incredibly fierce, and can grow to be more than 16 foot (nearly 5m long). However, by strapping cameras to these fascinating animals (researchers attached cameras and trackers to the dorsal fins of tiger sharks, giving them hours of footage each time.

seagrass meadows are incredibly biodiverse, incredible carbon sinks and a huge new one increase the amount by 40%

The footage that they received, revealed 92,000 square km (35,000 square miles) of seagrass ecosystem, stretching across the Caribbean seabed.

Perhaps, this demonstrates how little of the seabed we have explored, even in the shallow water, where the sea produces the most fish and plant matter. Many of the seagrass meadows are in water too deep for them to be seen from space, so satellites are useless, and only people on the ground can actually find out new things.

As such, it is incredibly expensive to send divers to all sea floors, however these sharks may well be a way for us to quickly find out where the sea grass meadows are.

What is important is that sea grasses are some of the most effective carbon sequestration that go on, which mean that by allowing these areas to grow, we could help save ourselves from runaway climate change.

It is thought, that at the moment we are loosing 7% of the worlds seagrass each year. The UK has lost 90% of our seagrass meadows .
