Animal Groups

An amphibian is an animal that has a backbone, thin moist skin, and typically lives both in water and on land. Examples include frogs and salamanders.

Vertebrates are animals that have a backbone. This group includes mammals, birds, reptiles, amphibians, and fish.

Invertebrates are animals that do not have a backbone. Examples include insects, spiders, and jellyfish.

Oviparous means egg-laying. Animals that are oviparous lay eggs that develop outside their bodies.

A mammal is a vertebrate animal that produces milk to feed its young and usually has hair or fur. Examples include dogs, cats, and humans.

A reptile is a cold-blooded vertebrate that has scales and lays eggs. Examples include snakes, lizards, and turtles.

Arthropods are invertebrates with an exoskeleton, segmented bodies, and jointed legs. Examples include insects, arachnids, and crustaceans.

Mammals are warm-blooded, have fur or hair, and produce milk for their young, while reptiles are cold-blooded, have scales, and lay eggs.

Amphibians typically have a life cycle that includes both aquatic (tadpole) and terrestrial (adult) stages.

Amphibians commonly live in moist environments such as ponds, lakes, and wetlands.
