Unknown type of activity/object
IUCN Red List Status: Endangered
Location: #Brazil, #Peru, #Colombia, #Ecuador
Found throughout the #Amazon and Solimões River systems, including major tributaries and large lakes. Their range spans lowland rainforest areas of Brazil, southeastern Colombia, eastern Ecuador, and southern Peru.
The #Tucuxi, a small freshwater #dolphin of #Peru, #Ecuador, #Colombia and #Brazil now faces a dire future. Once common throughout the Amazon River system, they are now listed as #Endangered due to accelerating population declines. Threats include drowning in fishing nets, deforestation, mercury poisoning from gold mining, #palmoil run-off, oil drilling, and dam construction. A shocking 97% decline was recorded over 23 years in a single Amazon reserve. Without urgent action, this elegant and playful river dolphin could vanish from South America’s waterways. Use your wallet as a weapon against extinction. Choose palm oil-free, and #BoycottGold #BoycottPalmOil #Boycott4Wildlife

Share to BlueSky Share to TwitterTucuxis are often mistaken for their oceanic dolphin cousins due to their streamlined bodies, short beaks, and smooth, pale-to-dark grey skin. But these freshwater dolphins are wholly unique—adapted to life in winding river systems where water levels rise and fall dramatically with the seasons.
What sets them apart is their remarkable intelligence and tightly knit social groups. Tucuxis are playful and curious by nature. They leap from the water in graceful arcs, sometimes spinning mid-air.
The Tucuxi, sometimes called the ‘grey dolphin’ due to their uniform colouring, resembles a smaller oceanic dolphin, with a streamlined body and slender beak. Their colour varies from pale grey on the belly to darker grey or bluish-grey along the back.
They travel in small groups of two to six, displaying coordinated swimming patterns. In rare cases, they may form groups up to 26 individuals, particularly at river confluences. Known for their agility, they leap and spin in the water with a grace that belies their size. Tucuxis are particularly drawn to dynamic habitats like river junctions, where waters mix and fish gather.
The Tucuxi inhabits the Amazon River basin, spanning: Brazil, Peru, Colombia, Ecuador These river dolphins occur as far west as southern Peru and eastern Ecuador, and as far north as southeastern Colombia. They are notably absent from Bolivia’s Beni/Mamoré system, the Orinoco basin, and upper reaches above major waterfalls or rapids.
Their range includes wide, deep rivers and lakes, avoiding turbulent rapids and shallow areas. Despite overlapping with the Amazon River Dolphin (Inia geoffrensis), Tucuxis do not enter flooded forest habitats and stay closer to main river channels.
Tucuxis feed on more than 28 species of small, schooling freshwater fish, including members of the characid, sciaenid, and siluriform families. During the dry season, fish are concentrated in shrinking waterways, making them easier to catch. In contrast, flooding season disperses prey into forested areas, beyond the Tucuxi’s reach. They prefer to feed at river junctions and along confluences, where nutrient-rich waters concentrate fish populations.
Little is known about their mating behaviours. However, individuals appear to remain within familiar ranges for many years, and females likely give birth to a single calf after a long gestation. Calves are dependent for an extended period, learning complex navigation and foraging skills in rapidly changing river systems. The estimated generation length is 15.6 years.
There is no comprehensive global population estimate. However, surveys from 1994–2017 in Brazil’s Mamirauá Reserve show a 7.4% annual decline—amounting to a 97% drop over three generations (da Silva et al., 2020). If this trend reflects the wider Amazon basin, the species could be on the brink of collapse.
Exact lifespans are unknown, but based on reproductive data and life history modelling, their generation length is around 15.6 years (Taylor et al., 2007), suggesting natural lifespans of 30–40 years.
Out-of-control palm oil expansion results in massive deforestation and run-off, clogging rivers with sediment and toxic agrochemicals. Gold mining adds mercury into aquatic ecosystems, where it bioaccumulates in fish—Tucuxis’ main food source. These pollutants cause reproductive harm, neurological damage, and immune system failure in dolphins.
Absolutely not. Tucuxis are intelligent, wild animals. Keeping them in captivity is deeply cruel and has no conservation benefit. Wild capture destroys families and can devastate local populations. If you care about these dolphins, say no to the exotic pet trade and the cruel zoo trade.
Research in Peru’s Pacaya-Samiria Reserve shows that Tucuxis prefer river confluences and wide channels, particularly during the dry season when fish density is higher (Belanger et al., 2022). Feeding activity is especially concentrated in areas where whitewater rivers meet blackwater tributaries, creating nutrient-rich hotspots.
The Tucuxi is vanishing before our eyes. To protect them:
• Boycott palm oil and gold products linked to Amazon destruction.
• Choose fish-free and vegan products to reduce pressure on river ecosystems.
• Support indigenous-led conservation across the Amazon.
• Campaign for a ban on destructive dams, and the end of illegal fishing.
