Species of Megatherium likely relied on their large adult body size to protect themselves against predators. [51] Like many other large mammals, Megatherium is suggested to have had a slow life cycle in accordance with a K-selection strategy. Megatherium americanum is suggested to have given birth to a single large offspring at a time. [52]
Priestia megaterium [1] (Bacillus megaterium prior to 2020) [2] is a rod-like, Gram-positive, mainly aerobic, spore forming bacterium found in widely diverse habitats. [3] [4] It has a cell length up to 100 μm and a diameter of 0.1 μm, which is quite large for bacteria. [5]
The group includes the heavily built Megatherium (given its name 'great beast' by Georges Cuvier [4]) and Eremotherium. An early genus that was originally considered a megatheriid, the more slightly built Hapalops, reached a length of about 1.2 metres (3.9 ft). The nothrotheres have recently been placed in their own family, Nothrotheriidae. [5]

Members of this genus tend to live around 25 to 30 years, reaching sexual maturity at three to five years of age. Three-toed sloths do not have a mating season but breed year-round. Male three-toed sloths are attracted to females in estrus by their screams echoing throughout the canopy. Sloth copulation lasts an average of 25 minutes. [22]
Oligophagy is a term for intermediate degrees of selectivity, referring to animals that eat a relatively small range of foods, either because of preference or necessity.
