Axolotl
Axolotls can regenerate their limbs, spinal cord, heart, and other organs without forming scar tissue, which is a rare trait among vertebrates.

The blue whale’s tongue alone can weigh as much as an elephant, and its heart is about the size of a small car.
Cheetah
Unlike other big cats, cheetahs cannot roar. They communicate with high-pitched barks, chirps, and growls.
Octopus
Octopuses have copper-based blood called hemocyanin, which is more efficient at transporting oxygen in cold, low-oxygen environments.
Hummingbird
Hummingbirds have the highest metabolism of any bird species, with heart rates that can exceed 1,200 beats per minute during flight.
Narwhal
Narwhals lack a dorsal fin, which helps them navigate under ice in their Arctic habitat.

The Turritopsis dohrnii jellyfish, known as the “immortal jellyfish,” can revert to its polyp stage after reaching adulthood, effectively restarting its life cycle.
African Elephant
African elephants have a highly developed brain and can use tools, show empathy, and recognize themselves in mirrors.
Mimic Octopus
The mimic octopus can change its shape, color, and behavior to resemble more than 15 different marine species, such as sea snakes and flatfish.
Archerfish
Archerfish can adjust the shape of their mouth opening to control the size and velocity of the water jet they use to shoot down prey.
Fennec Fox
]The fennec fox’s large ears help dissipate heat and provide excellent hearing, allowing it to detect prey moving underground.
Peregrine Falcon
Peregrine falcons have a special bony tubercle in their nostrils that helps them breathe while diving at high speeds.
