Cellular Respiration/ Reproduction
Sloths go through cellular respiration and not photothenyis because thats for plants. They perform only about ten percent of the average physical movement in mammals. Sloths breathe slowly and the respiratory surface of their lungs are smaller than average. The lungs of the Sloths are sponge like and look like a honeycomb.
They copulate towards the end of the dry season and early wet season, which occurs from August through October, which results in gestation and lactation occurring during times of plenty of food. Births occur from February to April, marking the end to the wet season and start of the dry season. One infant is born after a gestation period of 6 months. The interbirth interval is 1 year for maned sloths. normally one female sloth will only give birth once in
