African Bush Elephant
African Bush Elephant
Scientific Name
Loxodonta africana
Weight LB
6,000–13,000 lb
Average Life Span
60-75 years
Fact
An African Bush Elephant's trunk has around 40,000 muscles (more than your whole body!), allowing incredible dexterity to smell, drink, grasp, and trumpet, while their spongy foot pads let them walk quietly and even "hear" vibrations through the ground, making them surprisingly stealthy giants. They're also 'ecosystem engineers' and use mud baths as sunscreen to protect their sensitive skin from the sun and bugs, showing immense intelligence.

American Bison
American Bison
Scientific Name
Bison bison
Weight LB
699.6-2200 lbs
Average Life Span
15-40 years
Fact
American bison are surprisingly agile, capable of running up to 35 mph, jumping over 6 feet high, and swimming well, despite their massive size (up to 2,000 lbs). Their large shoulder hump, made of muscle, acts like a snowplow to clear snow for grazing in winter, and baby bison are born reddish-orange, earning them the nickname "red dogs".

Asian Elephant
Asian Elephant
Scientific Name
Elephas maximus
Weight LB
6,000–11,000 lb
Average Life Span
60–70 years
Fact
Unlike African elephants, where both males and females usually have tusks, among Asian elephants, only some males have large tusks. Females (and some males) have small, "tusk-like" teeth called tushes, which are usually not visible outside the mouth. Another easy way to tell them apart is by their ears: Asian elephants have smaller, rounded ears, while African elephants have ears shaped like the continent of Africa!

California Sea Lion
California Sea Lion
Scientific Name
Zalophus californianus
Weight LB
110-880 lbs
Average Life Span
17-30 years
Fact
A fun fact about California sea lions is their incredible vocal communication, using loud barks to defend territory, and their unique behavior called "rafting," where they float together with flippers up to regulate body temperature, sometimes even following dolphins to find food!. They're also highly social, intelligent, can hold their breath for 10 minutes, and are fast, agile swimmers that can reach speeds of 25 mph.

Capybara
Scientific Name
Hydrochoerus hydrochaeris
Weight LB
77-145.2
Average Life Span
6-12 years
Fact
Capybaras are the world's largest rodents, known for being extremely social and "chill," often seen relaxing with many other animal species like birds, monkeys, and even crocodiles, because their calm demeanor and semi-aquatic lifestyle make them peaceful companions in their native South American wetlands. They are excellent swimmers, can hold their breath for up to five minutes, and have their eyes and nostrils on top of their heads for stealthy observation.

A cheetah can accelerate from 0 to 60 mph (97 km/h) in just 3 seconds—faster than most sports cars!

Chimpanzee
Chimpanzee
Scientific Name
Pan troglodytes
Weight LB
60–110 lb (Female); 90–150 lb (Male)
Average Life Span
15–30 years (Wild); up to 50+ years (Captivity)
Fact
Chimpanzees were the first non-human animals observed making and using tools, a discovery by Jane Goodall that redefined what it means to be "human." They use sticks to "fish" for termites, rocks to crack nuts, and even crumpled leaves as "sponges" to soak up drinking water. Despite being smaller than humans, they are estimated to be 1.5 times stronger than us pound-for-pound due to the way their muscle fibers are structured for climbing and swinging.

Dolphin
Dolphin
Scientific Name
Delphinus delphis
Weight LB
330–1,400 lb
Average Life Span
40–60 years
Fact
Dolphins possess a biological sonar called echolocation. They emit high-frequency clicks that bounce off objects, allowing them to "see" their surroundings through sound. This sense is so precise that a dolphin can determine the size, shape, and even the density of an object from a distance.
