IUCN-listed endangered species
Also known as the pink river dolphin, the animal lives only in freshwater and is found throughout the Amazon river basins in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. Though the dolphin is protected in Brazil, its population continues to halve every decade and is now a <anchor>IUCN-listed endangered species</anchor> as poachers persistently hunt them for their fatty blubber to be used as bait to catch a carnivorous catfish. In other parts of the Amazon, the dolphin faces increasing threats of water pollution as well as dam installations creating habitat fragmentation. As female river dolphins bear only a single calf every four to five years on average, population numbers can be slow and difficult to recover.

# Amazon river dolphins now listed as ‘Endangered’ by IUCN

The update is part of assessments or reassessments of 35 cetacean species, subspecies or populations published on the IUCN Red List in November 2018

The dolphins of the Amazon river have been listed as “Endangered” by the International Union for Conservation of Nature (IUCN) in its latest “Red List” published in November 2018.

There are two types of Amazon river dolphins namely, the “boto” ( Inia geoffrensis) and the “tucuxi” ( Sotalia fluviatilis), which were once considered abundant in the Amazon.

Conducted by researcher Vera da Silva and her colleagues from the Instituto Nacional de Pesquisas da Amazonia in Manaus, Brazil, the research had warned that freshwater dolphins found in the Amazon River Basin were “dying off fast”, and could face extinction unless they were more vigorously protected against fishing.

The study had stated that the primary reason for the decrease in numbers was the dolphins’ use of flesh and blubber as bait for catfish, which have become widely available commercially. Killing the dolphins endangered their survival, particularly since the females bear a single calf on average every four to five years.

At the time of the May study, the IUCN had listed the freshwater dolphins’ status as "data deficient," meaning not enough was known about their numbers in the wild to assess the degree of threat to the population.

But the study had said that if the IUCN Red List considered the latest findings, both species would be classified as “Critically Endangered”.

With the new IUCN Red List, the researchers’ statements stand vindicated.

The new list also has assessments or reassessments of 34 other cetacean species, subspecies or populations. This is in addition to the 10 new assessments published in July 2018, and 19 published in November 2017.

Besides the Amazon dolphins, freshwater dolphins in other parts of the world are also facing extreme pressures. In the Indian Subcontinent, the Gangetic or Indus River Dolphin ( Platanista gangetica) found in the Ganga and Indus River Basins is considered “Endangered” by the IUCN. In China, the Yangtze River dolphin or “baiji” ( Lipotes vexillifer), was declared functionally extinct in 2006 due to human activities like overfishing, dam building, pollution and boat traffic.
