This includes two species of Tamandua (Silky Anteaters) and the Giant Anteater. The record of a tamandua from Cozumel, off Mexico, was probably in error. It may have been a common ancestor of "Myrmecophaga" and "Tamandua". Other mammals present include two-toed and three-toed sloth, collared peccary, northern tamandua and silky anteater. "G. lopezneyrai" has been found parasitizing the Southern tamandua ("Tamandua tetradactyla") in Venezuela. The southern tamandua uses its powerful forearms in self-defense. Like other anteaters, the northern tamandua has no teeth. The southern tamandua is listed as CITES Appendix II in southeastern Brazil. The tamandua is frequently kept as an exotic pet. The zoo recently enjoyed an unusual addition to their family, a baby tamandua named Star. Like other anteaters, the northern tamandua is highly adapted to its unusual diet. The most commonly seen of Costa Rica's three anteaters species is the northern tamandua. "O. tamandua" resembles fishes adapted to caves in several respects. The tamandua is mainly nocturnal, but is occasionally active during the day.
