African Elephant
Elephants can communicate using low-frequency rumbles that travel several kilometres through the air and the ground, and they may detect them through their feet.
Endangered
African Grey Parrot
An African grey parrot named Alex, studied for 30 years, learned over 100 words and could identify colours, shapes and numbers.
African Wild Dog
African wild dogs are among the most successful hunters in Africa; packs catch prey in a large majority of chases, far more often than lions.
Amazon River Dolphin
Amazon river dolphins turn pink as they age, and in the flood season they swim between the trunks of submerged rainforest trees.
Asian Elephant
Asian elephants have shown self-recognition in mirror tests, a sign of self-awareness found in very few animals.
Aye-aye
The aye-aye taps on wood with a long, skeletal middle finger and listens for hollow tunnels made by grubs, then gnaws a hole and hooks the larva out.
Basking Shark
The basking shark is the second-largest fish in the world, and it filters up to about 2,000 tonnes of water an hour through its huge open mouth.
Bonobo
Bonobo societies are led by females, and conflicts are often defused with social bonding, grooming and sex rather than violence.
Chimpanzee
Chimpanzees share about 98–99 percent of their DNA with humans and make tools, including sticks shaped to fish termites out of mounds.
