Animals that start with D range from the dolphin, which talks in clicks and whistles, to the dodo, a flightless bird last widely seen in 1662. This guide lists 77 animals that start with D, with photographs, scientific names and IUCN Red List status, sorted by group for homework, quiz nights and alphabet games.
Quick answer: animals that start with D include the dolphin, dog, duck, deer, donkey, dingo, dugong and dragonfly, plus the extinct dodo. Fifty-five of the 77 have their own entry with a licensed photo, from the dhole and the dik-dik to the diving bell spider.

Diet: Ice Age megafauna
IUCN status: known from fossils; not assessed by the IUCN
Most fossils come from the La Brea Tar Pits in Los Angeles. In April 2025 Colossal Biosciences announced gene-edited grey wolf pups it called “dire wolves”, but the IUCN SSC and many scientists said they are modified grey wolves.
Diplodocus
Scientific name: Diplodocus carnegii
Group: extinct dinosaur
Lives: western North America, Late Jurassic (about 152–149 million years ago)
Size: 24–26 m long
Diet: plants
IUCN status: known from fossils; not assessed by the IUCN
D. carnegii is one of the longest dinosaurs known from a complete skeleton. Find it in a list of all the dinosaurs.


Dimetrodon
Scientific name: Dimetrodon
Group: extinct synapsid
Lives: mainly Texas and Oklahoma, Permian (about 294–271 million years ago)
Size: 1.7–4.6 m
Diet: predator
IUCN status: known from fossils; not assessed by the IUCN
Dimetrodon had a sail on its back. It was not a dinosaur but a synapsid, more closely related to mammals, and it died out about 40 million years before the first dinosaurs.
Dunkleosteus

Scientific name: Dunkleosteus terrelli
Group: extinct fish
Lives: Late Devonian seas, about 382–358 million years ago
Size: typical adults about 3.4 m, largest about 4.1 m
Diet: predator
IUCN status: known from fossils; not assessed by the IUCN
This armoured fish was one of the first vertebrate apex predators. A 2023 study found it was much smaller than the old 6–10 m claims.
