Can sharks see? And do giraffes really give birth standing up? We answer your burning questions about the astonishing animal kingdom, and bring you closer to our natural world with the BBC Earth fact files.
Giraffa camelopardalis
With their long napes and lanky legs, giraffes are literally head and shoulders above the rest – towering over the arid African savannahs, they are the tallest mammals roaming the Earth.
Bradypus
Sloths are the slowest mammals to call this planet home, but their laidback lifestyle isn’t the only feature that makes them extraordinary.
Elephantidae
The elephant is the largest living land animal. This giant, plant-eating mammal lives in family groups with complex social orders and is capable of remarkable feats of memory – they do say elephants never forget!
Equus ferus caballus
The horse is a four-legged herd animal. Various breeds of the animal have been domesticated and are used for work, riding and as a source of food and milk. Historically, the domestication of horses helped humans to spread across the world and also improved their ability to farm.
Formicidae
Despite their tiny size, ants have long intrigued scientists with their exceptional work ethic and resourcefulness, and their sophisticated social structures.
Araneae
Despite their creepy-crawly reputation, spiders are astoundingly diverse, ingeniously resourceful, and often surprisingly endearing.
Anthophila
Honeybees and bumblebees are the iconic representatives of this busy and buzzy insect, but there are actually more than 20,000 different species of bee.
Selachimorpha
Sharks are often characterised as vicious killers, but in reality, they’re a diverse and endangered group of creatures that add tremendous value to marine ecosystems.
Anuran
Frogs and toads are the largest and most diverse group of amphibians. They’re known for their long leaps, intriguing life cycle, and wide range of sophisticated croaks.
Serpentes
Snakes are often maligned for their sharp fangs and toxic venom, but these slithering reptiles are exceptional examples of adaptability, elegance and diversity.
Molluscs
Octopuses are so unique they’ve even been branded as "alien". They are some of the smartest yet farthest removed creatures from humans, and they are masters of camouflage and great puzzle solvers.
