HERRERA, Hansel; ESCOBAR-LASSO, Sergio; GONZALEZ-ANCIN, Héctor  and  BEAL, Marie-Cécile. Observaciones del nado de un grupo de monos aulladores (Alouatta palliata) en el Océano Pacífico de Costa Rica. Mastozool. neotrop. [online]. 2015, vol.22, n.2, pp.385-389. ISSN 0327-9383.

Mantled howler monkeys, Alouatta palliata, have been observed swimming in flooded forests, swamps, lagoons and rivers. This type of event had only been documented on solitary individuals in fresh water bodies so far. Therefore, the purpose of this note is to report, for the first time, a troop of A. palliata swimming from the continent to a nearby island in the Pacific coast of Costa Rica.
