List of animals on letter D

Deep-sea animals

Deep-sea animals

Type of animal science: Anatomy, ecology
Fields of study: Ecology, marine biology
The great depths of the sea, below about 150 feet, had always been considered azoic (without animal life). Oceanographic research has shown the ocean supports a large number and diversity of animals in all areas, from the surface to the bottom of the deepest parts, nearly six miles down.

Deer

Deer

Type of animal science: Classification
Fields of study: Anatomy, zoology
Deer are hoofed, artiodactyl mammals of the family Cervidae, having bony antlers, which are shed and regenerated annually.

Dinosaurs

Dinosaurs

Type of animal science: Classification, evolution
Fields of study:Anatomy, archaeology, evolutionary science, paleontology, physiology, zoology
Dinosaurs were one of the most successful early life-forms, thriving for more than 150 million years before becoming extinct by the end of the Cretaceous period. The reasons behind their longevity and their sudden extinction hold important implications for humankind’s own survival.

Dog

Dog

Type of animal science: Classification
Fields of study: Anatomy, zoology
Dogs are carnivorous mammals which belong to the Canidae family and share similar anatomical and behavioral traits with wolves and coyotes.

Dolphins, porpoises, and other toothed whales

Dolphins, porpoises, and other toothed whales

Type of animal science: Classification
Fields of study: Anatomy, marine biology, physiology, zoology
Toothed whales are cetaceans, suborder Odontoceti. They use teeth to capture cuttlefish, squid, and other prey. Some are endangered species perceived to be quite intelligent.

Donkey

Donkey

Type of animal science: Classification
Fields of study: Anatomy, evolutionary science, zoology
The donkey was domesticated from the African wild ass at least six thousand years ago.

Duck

Duck

Type of animal science: Classification
Fields of study: Anatomy, ornithology
Ducks are among the most common and widespread of aquatic birds. Like other members of the Anatidae family, they have webbed feet, a boat-shaped body, a dense covering of feathers, and a broad and somewhat flattened bill.
