New Species of River Dolphin Discovered

Published

on

Scientists in Brazil have discovered the first new river dolphin species since the end of World War One.

Named after the Araguaia river where it was found, the species is only the fifth known of its kind in the world.

Researchers say it separated from other South American river species more than two million years ago.

There are believed to be about 1,000 of the creatures living in the Araguaia river basin.

River dolphins are among the world’s rarest creatures.

According to the IUCN, there are only four known species, and three of them are on the Red List, meaning they are critically endangered.

These dolphins are only distantly related to their seafaring cousins, tending to have long beaks which let them hunt for fish in the mud at the bottom of rivers.

One of the best known species, the Yangtze river dolphin or baiji is believed to have gone extinct in about 2006.

South America though is home to the Amazon river dolphin, also known as the pink dolphin or boto, said to be the most intelligent of all the river species.

The new discovery is said to be related to the Amazonian, although scientists believe the species separated more than two million years ago.

“It is very similar to the other ones,” said lead author Dr Tomas Hrbek, from the Federal University of Amazonas.

“It was something that was very unexpected, it is an area where people see them all the time, they are a large mammal; the thing is, nobody really looked. It is very exciting.”

The scientists say there are some differences in the number of teeth and they suspect the Araguaia river species is smaller, but most of the clues to their separate nature were found in their genes.

By analysing DNA samples from dozens of dolphins in both rivers, the team concluded the Araguaia river creature was indeed a new species.

They acknowledge though that some experts may question whether or not the discovery is in fact, wholly distinct.

Top of the list of prizes is the chance to spend time with adventurer and wildlife expert Steve Backshall, a workout session with Nat Geo star Aldo Kane, a kayaking trip alongside white-water expert and diver Sal Montgomery and a Zoom call with ‘shark whisperer’ Cristina Zenato.

On top of that, some of the most admired companies in the diving and scuba industry have been quick to support the charity with fabulous prizes that make the £5 ticket price worth more than just a flutter.

Master Liveaboards, BSAC, Midlands Diving Chamber, Go Freediving and Blue Shark Snorkel have all generously donated experience prizes, while celebrated photographer Alex Mustard has donated a print and artists Scott Gleed and Olivier Leger have donated a sculpture and illustration to help boost the fundraising pot.

Fourth Element has donated Ocean Positive gear and LA watch company Nodus has gifted the charity a stunning dive watch. For land lovers, the charity has included a five star London hotel stay at Bankside Hotel plus a family visit to Longleat Safari Park in the roster of prizes.

Campaign director for Bite-Back, Graham Buckingham, said: “We’ve been overwhelmed with support from companies and individuals that we truly admire and who have supported us on our 20 year journey and we’re truly grateful to them all. While we feel incredibly proud of our achievements over the past two decades – and we are super excited about the next chapter – this prize draw isn’t a vanity project. It represents a real lifeline to our work and important advancements in the global protection of sharks. So we hope divers, dive clubs and even bargain hunters grab some tickets to make this a massive success.”

The charity hopes that the prize draw will generate crucial funds to launch a brand new, ground-breaking, campaign to enrol the public and increase support for the protection of sharks around the world.
