Habitat
This species inhabits coastal waters and estuaries along the western and eastern coasts of South America, from Brazil to southern Chile. They prefer shallow areas less than 200 meters deep, often near river mouths and upwelling zones where food is abundant. These environments provide protection from open ocean predators.
Diet
Burmeister's porpoise primarily feeds on small schooling fish like anchovies and sardines, as well as squid and shrimp. They hunt in small groups using echolocation to locate prey, typically feeding during the day in shallow waters. Their opportunistic feeding behavior allows them to adapt to seasonal prey availability.
Behavior
Burmeister's porpoise is highly social, often traveling in groups of 2 to 10 individuals, though larger aggregations can occur in feeding areas. They are mostly active during the day, exhibiting quick, erratic swimming patterns to evade threats, and are not known for aerial displays like some dolphins. They use echolocation for navigation and hunting but are generally shy and avoid boats.
Conservation Status
Burmeister's porpoise is listed as Data Deficient by the IUCN, with population trends uncertain due to limited data. Major threats include bycatch in fishing nets and habitat degradation from pollution and coastal development.
