Brown-throated Three-toed Sloth|
To the author's knowledge, the following is the only information bearing on hybridization in this family:
Bradypus tridactylus [Pale-throated Three-toed Sloth]
× Bradypus variegatus [Brown-throated Three-toed Sloth] A parapatric contact zone, which is often a sign of ongoing hybridization, exists in Venezuela, but the author has not as yet encountered any explicit report of hybridization.
