Campaign to save the giant manta ray
Conservation charities are working with the government in northern Peru in South America where a big campaign's started to help save the Giant Manta Ray and make sure the species is protected forever.
Kanina spent 6 months in Peru collecting important data about them.
There are concerns that over-fishing and destruction of habitat could be harming the species.
Changing attitudes about the species starts in the classroom and kids have been helping out.
They're the largest ray in the world (up to 8m wide!)
They can make migrations across the oceans, finding their way by following topographical maps using ocean landmarks, such as seamounts.
They're also extremely intelligent and possess the largest brain of any fish.
When swimming around divers, mantas can be extremely curious, often coming in for a closer inspection and swimming repeatedly through divers' bubbles.
