The Amazon River dolphin (also referred to as the pink River dolphin and botos) is a freshwater mammal that lives within the Amazon and Orinoco river basins that run through Brazil, Bolivia, Ecuador, Colombia, Venezuela, Guyana, and Peru. This species is smaller than other kinds of seawater dolphins and is known for its outstanding hearing. These dolphins must sleep in warm, shallow water areas because they need little or no blubber. River dolphins suffer in captivity with few aquariums ready to keep them alive.

Amazon River dolphins usually become additionally pink as they age, which has led to the species to be called 'the pink dolphin'.

River dolphins have exceptionally massive brains, and whereas dolphin groups are noted for swimming in teams, river dolphins tend to stay longer alone or among little groups of two to four dolphins. You may see an even bigger cluster of them in areas that are wealthy with food. However, it is less common with freshwater dolphins.

How do they reproduce?

In South America, spring is for the rainy season. Throughout this point, acres and acres of the rainforest will flood, turning into a vast tree-covered ocean. The water becomes deep enough for the river dolphins to swim between the trees. Mating season happens once the water recedes, and therefore the male and female dolphins are constricted to the river channels.

The dolphin species is polygamous, which means males mate with many females annually. However, females don’t mate each year. They mate every two to three years.

Female river dolphins are additionally drawn to males that are a brighter shade of pink. To attract and impress the female dolphins, freshwater dolphins smack the water with bunches of grasses or branches in their mouths. Once a female dolphin becomes pregnant, she’ll carry the calf for 11 to 15 months. The animal species offers birth to merely one calf. Once the baby dolphin is born, it'll nurse it for over a year.

What is their conservation status?

According to the IUCN Red List, the Amazon River dolphins were last assessed in June of 2018. The estimate of mature river dolphins isn't listed, however, it's expected that they're on a declining trend as they face several threats.

Would they make a good pet?

They would ideally make a good pet since they are curious and friendly towards humans, but we must keep in mind that these mammals were never meant to be taken out of the wild; therefore, it is best to let them be for their population to increase. They mostly fight with one other but do not harm humans and instead like to interact with them.

Did you know...

While not aggressive with humans, Amazon River dolphins would typically fight each other and leave good amounts of scar tissue. It’s hypothesized this scar tissue turns pink and could be a reason why older males tend to possess the distinctive pink coloration. A high level of rain causes the muddy bottoms of rivers to show a red or pink hue. Amazon river dolphin adaptations might have merely evolved to better mix in with their surroundings.

Amazon River dolphins are born gray, and males tend to become pink as they age. Additionally, this pink coloration remarkably only covers some components of their body, whereas areas of gray stay. It’s hypothesized that males with additional pink coloration are able to attract mates more in the river system.

The organization is buying instrumentation and provides for native residents to help in data-based sightings of resident Amazon River dolphins.
