Like other mammalian creatures, two-toed sloths reproduce sexually in which a female egg is fertilized by a male sperm cell. Sloths mate between the months of September and November, generally known as the dry period of the climate. When females are in heat they will often scream to attract nearby males.
Sloth copulation is rarely witnessed in the wild, but researchers have reported seeing it occur both with the male mounting the female from behind and face-to-face. The act is brief, ending in just a few minutes. The male may try to mate with her again a few minutes later.
Females give birth once every 15 months and to one baby at a time. Combine that with the fact that sloths live high in the jungle canopy and you can imagine that witnessing a sloth birth in the wild would be a truly rare event.
When it's time to give birth, the mother will usually descend to the lower canopy branches and give birth while hanging upside down. In this position, if the baby falls to the ground, it won't fall far, and the mother can climb down to retrieve her young.
Scream, then wait…
Sloths are mostly solitary animals, roaming the rainforests very slowly, upside-down and alone. But when it's time for a get-together, female sloths are not shy about what they need. They scream for sex, as loud as they can, trying to get the attention of every male sloth in the tri-state area.
You could have guessed it, but sloths are typically lazy when it comes to sex - although they will indulge in some swinging. It might not be the most fast-paced, frenetic love-making of the animal kingdom, but at least they do seem to put in a bit of effort - and even indulge in some swinging.
For animals, mating strategies include random mating, disassortative mating, assortative mating, or a mating pool. In some birds, it includes behaviors such as nest-building and feeding offspring. The human practice of mating and artificially inseminating domesticated animals is part of animal husbandry.
How long does it take? Sex is the only thing sloths do quickly. Copulation lasts less than a minute. After it is over, the dominant male will stay nearby for several days, mating with the female frequently and fighting off any other males that wander too close.
The longest ever recorded lifespan for any sloth species is 43 years. The average lifespan of two-toed sloths is believed to be up to 20 years.
Sloths are known reservoirs of the flagellate protozoan which causes leishmaniasis in humans, and may also carry trypanosomes and the protozoan Pneumocystis carinii.

We believe that it is all about communication and reproduction. Pheromones present in urine and faeces can provide a lot of important information about the individual animal. If the sloths just let everything go from the canopy, these messages would be easily lost.
Sloths only urinate and defecate once a week, said Schlott. “So when the floodgates open, it's a big production,” she said.
► Sloths were not strictly monogamous and showed a mixture of polygyny and promiscuity. ► Tolerance among males may stem from their limited mobility and the benefits of kin selection.
KidZone Animals. Sloths: Mating
Sloths generally attempt to reproduce once a year, but at times, they do not move enough in the course of a year to find a partner to mate with... When a female sloth is, however, ready to mate, she will yell out what is called a "mating scream" to signal to any nearby males.
Sloths are known for their incredibly slow-moving natures, but it turns out that such sluggishness also carries over into their bathroom habits. So much so that they only defecate every five to seven days on average, and actually lose up to one-third of their body weight in a single movement!
Adelaide Zoo is celebrating the life of one of its most iconic and oldest residents, Australia's last sloth, Miss C the Hoffmann's Two-toed Sloth.
Due to their inherent lack of aggression, sloths are not a threat to humans. Sloths are solitary creatures who want to be left alone, thus unlike household animals, they do not like to be touched. So, if you come too close for their comfort, they can be deadly and severely hurt people.
Modern sloths, however, are thought to have avoided the extinctions that wiped out their larger relatives because they ascended into the trees.
A baby sloth is strong enough to cling onto mom's fur from the moment they are born, but sometimes they fall from the canopy (all baby animals are a bit clumsy and sloths are no exception). When this happens, mom will slowly climb all of the way down to the forest floor to retrieve her baby.
2. Are female sloths good mothers? Female sloths give birth to one baby a year after a gestation period of six months. The baby sticks with the mother for about six months, grasping its mom's belly as she moves through the trees.
Two: Sloths Urinate and Defecate just once a week
They mate and give birth in the trees, but they appreciate a little more privacy when it's time to use the loo. Once they have relieved themselves, they can be up to 3 times lighter!
Not only do animals enjoy the deed, they also likely have orgasms, he said. They are difficult to measure directly but by watching facial expressions, body movements and muscle relaxation, many scientists have concluded that animals reach a pleasurable climax, he said.
Could we mate with other animals today? Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Pufferfish
Attracting females is hard work if you are male pufferfish. Rather than just sitting and waiting for females, males spend days creating symmetrical patterns in the sand that can reach up to 2 m in diameter. If happy with the male's creation, the female will lay her eggs in the centre of the circle.
