The answer is: C. Snake
The other four options are all birds. A tortoise is a reptile, a duck is a waterfowl, a whale is a mammal, and a crow is a passerine bird.
Snakes are reptiles that are characterized by their long, slender bodies and their lack of limbs. They are found in a variety of habitats, including forests, deserts, and grasslands. Snakes are carnivores and their diet consists of small mammals, birds, reptiles, and amphibians.
Birds are a group of warm-blooded vertebrates that have feathers, wings, and a beak. They are found on every continent except Antarctica. Birds are divided into two groups: flightless birds and flying birds. Flightless birds, such as ostriches and emus, have lost the ability to fly. Flying birds, such as eagles and hawks, have wings that allow them to fly.
Whales are a group of marine mammals that are characterized by their large size, their streamlined bodies, and their lack of hind limbs. They are found in all oceans of the world. Whales are divided into two groups: toothed whales and baleen whales. Toothed whales, such as dolphins and orcas, have teeth that they use to catch prey. Baleen whales, such as humpback whales and blue whales, have baleen plates that they use to filter food from the water.
Crows are a group of passerine birds that are characterized by their large size, their black plumage, and their intelligence. They are found in a variety of habitats, including forests, grasslands, and urban areas. Crows are omnivores and their diet consists of insects, small mammals, fruits, and vegetables.
