Zoo animal life expectancies

Zoo animal life expectancies vary greatly depending on species, habitat, diet, and quality of care provided by the zoo. Generally, animals in accredited zoos tend to live longer than their counterparts in the wild due to access to veterinary care, a controlled diet, protection from predators, and a lack of natural threats such as diseases or habitat destruction. However, it's important to note that not all species thrive in captivity, and some may experience health issues or behavioral problems due to confinement.

In zoos, large mammals like elephants, big cats, and primates often have longer lifespans compared to their wild counterparts, with some individuals living well into their 40s or even 50s. For example, Asian elephants in captivity can live up to 60 years, while in the wild, their average lifespan is around 48 years. Similarly, lions and tigers in zoos may live into their late teens or early 20s, whereas their wild counterparts typically have shorter lifespans due to factors such as competition, predation, and disease.

Smaller animals like birds, reptiles, and fish also benefit from the controlled environment of zoos, with many species surpassing their wild counterparts' lifespans. For instance, some parrot species can live over 50 years in captivity, whereas in the wild, their lifespans are generally shorter due to predation and habitat loss.

Despite efforts to replicate natural habitats and provide quality care, some species still face challenges in captivity, leading to shorter lifespans or health issues. Factors such as stress, inadequate diet, limited space, and breeding difficulties can affect the overall health and longevity of zoo animals.

The chart below created by Reddit user LuisaViz shows the minimum and maximum or median life expectancy estimates of selected animals in zoos.

For creating this visualization, longevity estimates are derived from studbooks for the animal population in North American zoos and aquariums. Existing large-scale datasets on animal lifespans from wild population mostly consist of maximum longevity values and therefore are not comparable with median life expectancy estimates depicted here.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Moose population in North America

The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moose population was measured at around one million animals. The most abundant moose population (about 700,000) lives in Canada. About 300 000 moose remains in nineteen U.S. states Alaska, Colorado, Connecticut, Idaho, Maine, Massachusetts, Minnesota, Montana, Michigan, Nevada, New Hampshire, New York, North Dakota, Oregon, Utah, Vermont, Washington, Wisconsin, and Wyoming. The largest moose specimens are found in Alaska 200 thousand moose. Below the map shows the size of US states scaled by the moose population.     Via
