Biology

Size

Head and body length averages 50-60 cm and tail length 5 to 6 cm.

Bradypus have a body weight of 4 - 4.5 kg (Merret, 1983).

Reproduction

Reproduction is thought to occur throughout the year, with one young born annually, following a gestation period of 4 to 6 months (Hayssen et al., 1993). 

Most births occur at the beginning of the dry season from late July to September in northern Guyana (Beebe, 1926).
