Amazon river dolphins are at great risk of extinction. It's estimated that the population of these dolphins drops by half every decade due to bycatch and the intentional use of their meat as bait for piracatinga fishing. Sea Shepherd has been in the Amazon since 2021 for a long-term study of the population of porpoises and tucuxis in partnership with INPA (National Institute for Research in the Amazon). This campaign aims to deepen knowledge of the health of these species to promote their conservation, to share knowledge through educational engagement with local communities, and expand awareness of the preservation of these dolphins within Brazil and throughout the world.
