What do Pink Dolphins Eat?

Pink dolphins eat crabs, catfish, small river fish and even small turtles.

As crabs and turtles have to be catch mainly at the bottom of the river, pink dolphins spend a lot of time while swimming looking at the bottom of the river for food.

The boto cervical vertebrae are not fused allowing them to move their head up to 180 degrees, which is a great help for hunting in shallow waters and floodplains.

Hunting fish require some techniques like herding, where they round a fish pod to concentrate fish and take turns for feeding. This procedure is largely used by their oceanic cousins.

Physical Description of Pink Dolphins

In the Amazon Region…There is a legend about the Boto or Pink Dolphin. According to the legend, the Boto turns from man to dolphin and backwards, changing shape at will.

The legend also states that when dolphins find young women on the shore, they changes shape and impregnate them.

This comes from the similarites between certain body parts of the Boto and humans.

There are several other superstitions about the Pink Dolphins in the Amazon River and around.

Pink dolphins can be found in pink, light gray or brown colors but there is not conclusive evidence of the reason why pink dolphins are pink.

It could be an adaptation to the river life or caused by the presence of capillaries near the surface of the skin what provide them such impressive color. Additionally, pink dolphins get pinker when they are excited or surprised, resembling blushing in humans.

The Amazon River dolphin is between six and eight feet long, and weighs between 185 and 355 pounds when it is fully grown.

River dolphins are typically smaller than sea dolphins but they have longer snouts, an adaptation provided by evolution, which is needed to hunt at the bottom of the river. River dolphins also tend to have more pointy teeth than sea dolphins.

Most species of river dolphins are almost blind, due to navigating muddy waters, but their brains are extremely large and well developed, however pink dolphins are considered to have a relatively good sight.

Unlike sea dolphins, river dolphins have what resembles fingers on the ends of their flippers, and their dorsal fins are much smaller than that of sea dolphins or even have humpbacks instead of dorsal fins like the pink river dolphin.

Behavior of Pink Dolphins

Pink dolphins appear to be the friendliest of all the river dolphins when approaching to humans and some stories of people being pushed to the shores by them are common among some tribes in the Amazon.

They swim up to 30 kilometers in one day, although they usually swim slowly looking for food at the bottom of the river.

How do Pink Dolphins Reproduce?

Males and Females mate to start a gestation period which is believed to last from nine to twelve months. Copulation is performed between males and females belly to belly.

Pink dolphins deliver their babies when the Amazon River is at its high between the months of May and July.
