D is the letter of the deer family, man’s best friend, and a few creatures stranger than fiction — including a wolf from the Ice Age that really existed. Here are 17 real animals that start with D, with fun facts and links to our deepest guides.

Wild animals that start with D
A few of these D animals deserve more than one line. Here are the wildest stories behind the letter.
Dingo
The dingo arrived in Australia thousands of years ago and became the continent’s top land predator. Dingoes rarely bark — they howl like wolves — and they can rotate their heads farther than most dogs and even use their paws almost like hands when handling food. Wild dingoes hunt everything from rabbits to kangaroos.
Dire wolf
The dire wolf wasn’t invented for fantasy TV — it was a real predator that roamed the Americas until about 10,000 years ago. Heavier and more powerfully built than today’s gray wolves, it hunted Ice Age giants like ancient horses and bison. Thousands of dire wolf skeletons have been pulled from the La Brea Tar Pits in Los Angeles.
Dugong
The dugong grazes underwater meadows of seagrass along warm coastlines from East Africa to Australia, tearing up plants with a bristled, downturned snout. It’s related to the manatee but has a fluked tail like a whale’s. Sailors who glimpsed dugongs long ago may have helped start mermaid legends.
Dik-dik
The dik-dik is one of the smallest antelopes on Earth — a full-grown adult stands barely a foot tall at the shoulder. Pairs mate for life and mark their tiny territories with scent from glands near their eyes. Their name comes from the whistling ‘dik-dik!’ alarm call they make when startled.
Dolphins
Dolphins hunt using echolocation, sending out rapid clicks and reading the echoes so precisely they can find fish hiding under sand. Bottlenose dolphins even call each other by name, using signature whistles unique to each individual. Some river species, like the pink Amazon river dolphin, live in freshwater far from any ocean.
Dung beetle
The dung beetle may be, pound for pound, the strongest animal on Earth — some can pull over a thousand times their own body weight, like a person towing six loaded buses. Rollers sculpt balls of dung and steer them in straight lines, and researchers proved some species navigate by the stripe of the Milky Way at night. In clearing waste, they quietly fertilize grasslands on every continent except Antarctica.
D animals to explore in depth
This is World Deer, so the letter D is our home turf. Start with these in-depth guides.
Deer
Deer are what this site is named for, and our guide to the world’s deer species tours all of them — from moose the size of horses to pudu smaller than beagles. Every deer species grows and sheds its antlers each year, the fastest-growing bone known in the animal kingdom. New to deer entirely? Our Deer 101 guide covers the basics of how they eat, move, and survive.
Dogs
Our dog section covers the animal that has been humanity’s partner longer than any other — dogs were domesticated from wolves well over 10,000 years ago, before farming even existed. From breed guides to care and feeding, it’s all there, including how a chihuahua and a Great Dane can possibly be the same species.
Desert hedgehog
The desert hedgehog is the smallest hedgehog species, at home in the Sahara and the deserts of the Middle East. It shelters from brutal daytime heat in burrows and comes out at night to hunt insects — and it will even tackle scorpions. Its dark muzzle and oversized ears set it apart from its garden-dwelling cousins.

Questions kids ask about D animals
What’s a cool animal that starts with D?
The dire wolf wins for sheer wow factor — kids are often amazed to learn it was a real animal, not a fantasy invention, and that it hunted Ice Age megafauna in the Americas. Among living animals, the dugong (a sea cow that may have inspired mermaid tales) and the cat-sized dik-dik are hard to top.
How many kinds of deer are there?
Scientists recognize more than 50 living deer species, from the mighty moose down to the tiny pudu of South America, which stands barely over a foot tall. They live on every continent except Antarctica and Australia (though people have introduced deer there, too). Our deer species guide profiles them family by family.
Were dire wolves real?
Yes — completely real. Dire wolves lived across the Americas during the Ice Age and died out around 10,000 years ago, probably as the huge prey animals they depended on disappeared. We know them incredibly well because thousands of their skeletons were preserved in the La Brea Tar Pits in California.
Do dolphins sleep?
Yes, but in one of the strangest ways in nature: a dolphin sleeps with half its brain at a time, keeping one eye open while the other half rests. That’s because dolphins are conscious breathers — they have to remember to surface for air — so fully switching off would be dangerous. Mothers and calves can even swim slowly in formation while napping this way.
D runs from the family dog to a wolf out of the Ice Age — and right through the middle of everything this site is about. If deer caught your attention, you’re in the right place: World Deer has hundreds of deer articles waiting beyond the links above.
