Pink Dolphins Sighting

The playful pink river dolphin is one of the most loved amazon river species. Boating on the Amazon, we will stop to call the pink dolphins (bufeo colorado) to come and say hello. If you are quiet, you can see them swimming, leaping, and playing about near the boat.

Pink Dolphin Sighting.
 

Take a twenty-minute boat ride down Amazon River to try to spot some “pink dolphins” (Inia Geoffrensis) as they leap and swim about. The Amazon River dolphins are one of the few species of fresh water and the most well-known river dolphins. They range in color depending on their age; juveniles are dark gray on the dorsal side, lighter gray on the ventral side medium sized, with long beaks, a stocky body, and prominent forehead. As they mature, the ventral side and flanks turn pink; you may think they’re almost mystical. They become lighter with age, tinged with white and blue-gray coloring. The pink dolphins are often found singly or in pairs. Watch as they gregariously bound and show off sometimes even alongside the boats.

Swimming with pink river dolphins

Swimming with pink river dolphinsBecause pink river dolphins are so friendly, swimming with them is possible on a guided boat excursion. They often swim right to the boat in order to get a closer look at their visitors. With the supervision of an experienced naturalist, don’t be afraid to grab a floatation device and jump in the water to get up close and personal with these gentle mammals.

If you are worried about potentially dangerous creatures lurking beneath the surface, there is really nothing to fear. Pink river dolphins have sophisticated sonar which allows them to send out electromagnetic pulses that bounce off of solid objects under water. If there are pink river dolphins around, then it is safe to say that there are not other predators posing immediate threat.

So make sure you bring your bathing suit and a waterproof camera. A snapshot of the pink river dolphin will definitely be one for the Amazon adventure scrapbook.

Did you say a pink dolphin?

Did you say a pink dolphin?Yes, Amazon river dolphins are pink. Scientists are not entirely sure why, but a common theory suggests that their rosy pigment comes from their blood vessels visible through a thin layer of skin. In fact, Amazon river dolphins become more pink in color when excited, much like humans when we blush.
These dolphins are an endemic species to the Amazon Rainforest, meaning that they are not found in any other part of the world. While there are other freshwater dolphins in places like China and parts of Southeast Asia, there are only 2 documented species living in the Amazon Basin of South America. Of those 2 species, the pink river dolphin is the most charismatic.
In all honesty, the pink river dolphin is not the cutest water-dwelling animal of the Amazon. These dolphins are larger than a person, about 8 feet long, with a bulge on the head and a long, thin snout that is curved upwards, as if it is permanently smiling. They have large flippers and a short crest where the dorsal fin should be. They are not particularly fast swimmers, but their unique bone structure allows them to maneuver with agility through trees and brush when the river floods during the high water season.

Physical description

Physical descriptionIn 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.

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.
