However, it is necessary to consider the disperse use of habitats by otters, mobility of groups, and rarity of direct sightings, even during the dry season in the region.

Winged refers In those regions, protected areas are important instruments to conserve populations of giant river otters, shielding the species from the human pressures and favoring population recovery in natural environments, and, thus, increasing its chances of survival (ICMBio, 2010). They form cohesive family groups, usually with 3-12 individuals, composed by one reproductive couple and several young from different generations (DUPLAIX, 1980; SCHWEIZER, 1992; CARTER and ROSAS, 1997; STAIB, 2005).

Years ago, they lived in tropical forests and wetlands, but the presence of human beings has drastically changed this situation. From September 2001 to September 2010, field excursions of ∼6 days, typically involving 3 … A special emphasis was given to the characterization of negative human impacts resulting from the growth in human and animal populations and from the recolonization of historical areas of occurrence by giant river otters in the reserve.

The species is classified by the IUCN as endangered (A3cd) due to its small populations, restricted occurrence areas, and local extinctions recorded along its historical geographic range (DUPLAIX et al., 2008). Their vulnerability to human impacts together with an intensive hunting pressure in the past century led giant river otters to a worrisome conservation status (CARTER and ROSAS, 1997; DUPLAIX et al., 2008). 7 fascinating facts about giant otters As the name suggests, the giant otter is the world's largest otter species and is well-known from wildlife documentaries.
