Pink dolphins, also known as Amazon River dolphins or Boto dolphins, are a rare and enchanting species that inhabit the waterways of the Amazon rainforest. Known locally as “toninas,” these mammals are widely distributed across the Amazon and Orinoco river systems, including regions in Colombia such as Meta, Guaviare, and Amazonas.
These unique creatures are not only a sight to behold but also play a crucial role in the ecological balance of the region. They are considered one of the most intelligent and social species of dolphins, displaying complex behaviors and forming strong bonds with their family members. Their distinctive pink coloration often intensifies during active swimming due to increased blood flow.
Threats to this rare species
Pink dolphins are facing a sharp decline due to a range of human-induced threats. Habitat destruction, driven by deforestation and mercury contamination from mining, is degrading the Amazon’s river ecosystems and limiting the dolphins’ ability to survive. Illegal fishing practices also endanger these animals, as they are often entangled in nets or hunted for their meat and oil—used in traditional medicine and sometimes sold for up to $1,700 per dolphin. Climate change further compounds these threats by altering river flows and disrupting their natural habitat. As a result, pink dolphins are classified as endangered by the International Union for Conservation of Nature (IUCN).
Pink dolphins and conservation tourism in Colombia
In Colombia, pink dolphins can be observed in regions like the Amazonas Department near Leticia, and in the Guaviare and Meta Departments, where they appear year-round. Responsible eco-tourism is helping to protect these endangered animals by promoting non-invasive observation from boats or platforms. Feeding or disturbing the dolphins is prohibited to prevent dependency on humans. Through these initiatives, tourists are educated about the importance of preserving the Amazon ecosystem, supporting local conservation efforts that are vital to the survival of pink dolphins.
