Ingestion of invertebrates, seeds, and plastic by the Amazonian manatee (Trichechus inunguis) (Mammalia, Sirenia).
Aquatic Mammals 38(3): 322-324. DOI: 10.1578/AM.38.3.2012.322.
–ABSTRACT: The living Sirenia belong to the only group of herbivorous aquatic mammals which occur in river systems and coastal tropical and subtropical waters. From this group, the Amazonian manatee (Trichechus inunguis) is the smallest species, exclusively from fresh-water and endemic to the Amazon Basin. Sirenians are monogastric herbivores with post-gastric digestion and a low metabolic rate. Aquatic and semi-aquatic macrophytes are the main food source for Amazonian manatees, and the species composition and abundance of these plants are strongly influenced by the Amazonian hydrological pulse, which consequently influences the annual supply of food for the manatees. As accidental ingestion of microorganisms and seeds does not affect the health of the manatee even when not digested, the major concern is centered on the growing process of environmental degradation, mainly caused by indirect and direct deposition of waste in the rivers of the Amazon.
