Fernando Trujillo, a marine biologist and the scientific director of Fundación Omacha, an NGO that promotes conservation in Colombia and leads a program to protect river dolphins throughout South America, says dolphin watching could be conducted in a way that respects the animals’ natural behavior, but it would require training for both local guides and visitors. Occupying the Amazon and Orinoco river basins, which cut across the northern half of the South American continent, these freshwater mammals were historically abundant, and are protected today by Brazilian law; it is illegal to kill them. There aren’t strong enough laws to make fishermen report what they catch.”, Marcelo Oliveira, a conservation specialist at World Wildlife Fund Brazil (WWF), agrees with that analysis.

These skilled, sharp-toothed hunters, often reaching more than eight feet in length, are well adapted to shifting river levels. Occupying the Amazon and Orinoco river basins, which cut across the northern half of the South American continent, these freshwater mammals were historically abundant, and are protected today by Brazilian law; it is illegal to kill them. Powerful jets of water spray out of their blowholes as these freshwater mammals take in air before submerging. Due to that long gestation and nursing period, females only reproduce every three to five years. “Bycatch sees so many dolphins caught in fishing nets, gold mining in the region has led to mercury poisoning in the water, and the construction of hydroelectric dams has reduced their habitat and genetic pool,” he explains. A spokesperson for the Ministry of Agriculture, Livestock and Supply said it had not yet extended the moratorium because “it is necessary to evaluate its effects on the recovery of populations of porpoises and caimans in order to verify the effectiveness of this fisheries management measure.” When asked by Mongabay to comment, the ministry did not provide a timeframe for this evaluation period.

In the past, the boto’s mythic powers protected it. Its fossils were discovered near Piña, Panama. After that, the mother feeds a calf underwater for two years.

TEFÉ, Amazonas state, Brazil — A pair of pink Amazon river dolphin emerge for just a moment, arcing above the chocolate brown waters inside the Mamirauá Institute for Sustainable Development, a research facility at the tropical heart of the Brazilian Amazon. This not only led to the most accurate dolphin population estimation to date, but also to building a regional network of dedicated specialists grouped under the South American River Dolphin Protected Area Network. “It’s not a fight between the two. “Because botos have long been considered to be a sort of mythical beast that could do weird things, [people] just prefer not to risk negative consequences of catching them … But when you’ve got so many gill nets and there were some dolphins that were learning how to take fish from the nets, which of course pissed off the fishermen, then over a space of five or 10 or 15 years, this kind of protection brought about by the mythology—I think it almost evaporated.”.
