These are: the malleus, incus and stapes. These bones have the function of amplifying the sound that reaches the eardrum and transmitting it to the brain.<\/p>\n<p>In several species of fossils sloths these bones have been found preserved, and in the case of <i>Lestodon<\/i> and <i>Glossotherium<\/i>, they have been studied to evaluate the hearing capabilities.<\/p>\n<p>These studies showed that the bones of the middle ear of these sloths were very large compared to other terrestrial mammals, with a total mass similar to that seen in the middle ear bones of the Asian elephant. This implies a loss in hearing acuity for high frequencies, but it is an advantage for the detection of low-frequency sounds.<\/p>\n<p>One possible explanation is that these sloths could use low frequency sounds for long-range communications.<\/p>","protected":false},"excerpt":{"rendered":"<p>&nbsp; What could sloths hear?
