* It has got very small eyes and is almost blind.

* The river habitat where it lives is murky and sight is a sense hard to use in these conditions.

* Instead, these dolphins rely on hearing, and use echolocation to get a picture about their surroundings.

* Many other dolphins also use echolocation, but most of them rather combine it with eye-sight.

* Pink river dolphins, however, have much worse eyesight than most other dolphins. They can barely tell night from day by seeing.

* They use a primitive, but very sensitive echolocation system.

* They have a very flexible neck compared to other dolphins, so they can turn their heads and follow their prey.

* To vary the pattern of their solar signal, they can change the shape of their melon.

* They can perfectly locate their prey, which is piranha, catfish, and other small creatures living in the Amazon river.
