Strawberry Poison Dart Frog
Measuring no more than an inch long, the strawberry poison dart frog seems deceptively unassuming.
Blood Red Glider
It makes this list of red animals because the backside of the butterfly is covered by a bright blood-red color fringed with black markings.
Siamese Fighting Fish
Clad in bright, extravagant colors and massive fan-like fins, the Siamese fighting fish, also known as bettas, were originally from Southeast Asia's freshwater lakes.
Scarlet Ibis
These large wading birds, which can be found along the wetlands and coast of South America and the Caribbean, are covered in scarlet plumage except for their black wingtips.
Scarlet Macaw
Scarlet Macaws top the list of red animals for their iconic and colorful plumage. Measuring about 33 inches from beak to tail, they rank among the largest parrots in the entire world.
