There is a new sloth to look for at Smithsonian's National Zoo, although spotting her may require the same patient pace that she keeps herself. Olive is a four-year-old southern two-toed sloth who made her public debut in Washington, D.C. in August 2026.
According to the Zoo's September introduction to its newest animals, Olive has already earned a reputation for being curious and spirited. She has explored her new home, ventured below the vines to investigate her surroundings and even shown an interest in a water hose used for enrichment.
A slow animal with a curious streak
Sloths are often treated as symbols of doing nothing, but Olive is a neat reminder that moving slowly does not mean lacking curiosity. Her keepers have watched her explore different parts of the habitat and interact with Darlene, a female agouti who shares the space.
The water-hose moment is especially charming, but it also tells us something useful about good animal care. Enrichment gives an animal opportunities to investigate, choose and respond to something that changes in its environment. It is not about making a sloth perform. The point is to provide safe experiences that encourage natural movement, attention and decision-making.
Individual personality matters too. A species profile can tell us what two-toed sloths generally eat or when they tend to be active, but it cannot predict every preference of one particular animal. Olive's keepers are still learning what interests her, which routes she favours and how she uses the habitat.
What kind of sloth is Olive?
Olive is a southern two-toed sloth, also known as a Linnaeus's or Linné's two-toed sloth. The Zoo's two-toed sloth species profile identifies the species as Choloepus didactylus. In the wild, these sloths live in the tropical forests of northern South America and spend most of their lives in the tree canopy.
The name can be slightly misleading. Two-toed sloths have two long claws on each front foot, but three on each back foot. Their limbs and large curved claws form a strong hanging system, allowing them to sleep, eat and travel beneath branches.
The Smithsonian describes them as primarily nocturnal and naturally deliberate movers. A low metabolic rate helps them conserve energy, while their slow digestive system takes its time processing leaves, shoots, fruit and other plant material. Their pace is not a character flaw. It is part of a specialised way of living on a modest energy budget.
Olive's carefully planned move
Olive arrived from Audubon Aquarium in New Orleans in July. The move followed a recommendation from the Association of Zoos and Aquariums' Species Survival Plan, a managed programme that coordinates animals in participating zoos with long-term population health in mind.
At Smithsonian's National Zoo, she joins Vlad, a 40-year-old male southern two-toed sloth. Keepers hope the pair may eventually produce young, but the announcement sensibly makes no promise. Introductions, compatibility and breeding all happen on the animals' timetable, and sloths are not known for rushing a relationship.
That distinction matters. Olive is not a rescued wild sloth being prepared for release, and a zoo birth would not by itself repair lost rainforest. Managed populations can support education, husbandry knowledge and species planning, while wild sloth conservation still depends on protecting connected forest and reducing trafficking.
Why choice and space matter
Two-toed sloths are mostly solitary in the wild. They are also canopy specialists, built to move through a three-dimensional network of branches rather than across open ground. A suitable habitat therefore needs more than a single perch. It should offer height, secure routes, resting choices and places where an animal can retreat from attention.
Olive's early exploration is encouraging, but visitors should not expect a constant show. She may be asleep, hidden or active when the building is quiet. That is normal sloth behaviour. Respectful wildlife watching means enjoying whatever the animal chooses to do, even when the day's headline event is a nap behind some leaves.
The bigger story behind a new arrival
Olive's arrival is a cheerful zoo update, but her species also points back to the rainforest. Smithsonian notes that two-toed sloths face habitat loss from logging and pressure from wildlife trafficking. Their slow, arboreal lives depend on forests that remain connected enough to provide food, shelter and safe movement.
For visitors, Olive can make those distant habitats feel a little less abstract. Her hooked claws, deliberate movements and preference for the upper parts of her home all make sense when viewed as rainforest adaptations. The best response is not to wish for a pet sloth or a close-contact selfie. It is to appreciate the animal on her terms and support responsible wildlife organisations and forest-friendly choices.
Welcome to Washington, Olive. May your new home contain plenty of good branches, peaceful naps and the occasional fascinating water hose.
