How to Tell if a Giant Manta Is Pregnant? Give Her an Ultrasound.

Scientists work with giant manta rays. They want to know if these big fish have babies. It is hard to see if a manta ray is pregnant because they live in the ocean. Mantas are very big and they move a lot.

Now, scientists use a special machine. It is called an ultrasound. An ultrasound helps them see inside the manta ray's body. They use it underwater. This is a new way to learn about manta rays. They put the ultrasound on the manta's belly. Then, they look at a screen.
