Elephant (Land) β Lifespan: ~60-70 yrs, Top speed: ~25 km/h
The largest land animal on Earth. An elephant's trunk has around 40,000 muscles, letting it perform delicate tasks like plucking a single leaf as well as powerful ones like lifting a log.
Cheetah (Land) β Lifespan: ~10-12 yrs, Top speed: ~110-120 km/h
The fastest land animal on Earth, able to accelerate from a standstill to 100 km/h in just about 3 seconds.
Giraffe (Land) β Lifespan: ~20-25 yrs, Top speed: ~60 km/h
Despite its long neck, a giraffe has exactly 7 neck vertebrae β the same number as a human. Each individual bone is simply much longer.
Lion (Land) β Lifespan: ~10-14 yrs, Top speed: ~80 km/h
In most prides, the lionesses hunt cooperatively, while the males mainly defend the pride and its territory.
Giant Panda (Land) β Lifespan: ~20 yrs (wild), Top speed: ~32 km/h
Though a member of the bear family, pandas spend most of their day (over 12 hours) eating bamboo, since they need to eat large quantities due to low digestive efficiency.
Kangaroo (Land) β Lifespan: ~6-8 yrs (wild), Top speed: ~70 km/h
One of the few animals that cannot walk backward, which is part of why it's often used as a symbol of Australia.
Blue Whale (Sea) β Lifespan: ~80-90 yrs, Top speed: ~30 km/h
The largest animal ever known to have existed on Earth β its heart alone weighs about 180 kg, and its heartbeat can be detected from several kilometers away.
Dolphin (Sea) β Lifespan: ~40-50 yrs, Top speed: ~30-37 km/h
Dolphins sleep with only half their brain at a time (unihemispheric sleep), letting them keep breathing and stay alert to their surroundings even while resting.
Octopus (Sea) β Lifespan: ~1-2 yrs, Top speed: ~40 km/h (burst)
An octopus has three hearts, and its blood is blue because it uses a copper-based pigment (hemocyanin) to carry oxygen instead of iron.
Seahorse (Sea) β Lifespan: ~1-5 yrs, Top speed: very slow
One of the rare animal species where the male carries and gives birth to the young β the female deposits eggs into the male's brood pouch, where he incubates them.
Peregrine Falcon (Sky) β Lifespan: ~15-20 yrs, Top speed: ~320 km/h (dive)
The fastest animal on Earth, reaching speeds over 300 km/h during a hunting dive.
Hummingbird (Sky) β Lifespan: ~3-5 yrs, Top speed: ~50-60 km/h
Hummingbirds flap their wings about 50-80 times per second and are the only birds capable of flying backward.
Arctic Tern (Sky) β Lifespan: ~30 yrs, Top speed: ~40 km/h
The Arctic tern migrates between the Arctic and Antarctic every year, covering roughly 70,000 km β believed to be the longest migration of any animal.
