Resumen

We present the first record of maned sloth (Bradypus torquatus) consumption by the tiger shark (Galeocerdo cuvier). Our record is based on the analysis of stomach contents of a tiger shark captured off the coast of Rio de Janeiro state, southeastern Brazil. Although it is not possible to distinguish between a predation and scavenging event, we consider it likely that the sloth was consumed while dispersing between the islands of the region. We also comment on the heretofore unforeseen risks of aquatic dispersal by xenartrans.
