A new species was discovered in the rain forest. Scientists determined that this new species is an animal but have not classified it. This new species has a backbone, lives on land, walks on four legs, is covered in dry scales, and lays eggs which it buries. The scientists asked a group of students to develop a model for classifying the animal. The students used these sources to create their model:

How should the scientists classify this new species?

• This new species is an invertebrate and should be classified as a fish because it lives in water and lays eggs.

• This new species is a vertebrate and should be classified as a mammal because it lives on land and lays eggs.

• This new species is a vertebrate and should be classified as a bird because it lives on land and incubates its eggs.

• The new species is a vertebrate and should be classified as a reptile because it lives on land and lays eggs that it buries to hide them from predators.
