Amphibians: Amphibians are a group of animals that can live both in water and on land. Their life cycle typically involves metamorphosis, starting from an aquatic larval stage (such as tadpoles) and developing into terrestrial adults (such as frogs or salamanders).
Reptiles: Reptiles are a group of cold-blooded animals characterized by scaly skin and laying shelled eggs. They breathe air and typically have four legs, although some reptiles, such as snakes, have evolved to be legless.
Mammals: Mammals are a group of animals characterized by having mammary glands that produce milk to nourish their young. They are warm-blooded, have fur or hair on their bodies, and most give birth to live young. Mammals include a wide range of animals such as humans, dogs, cats, cows, whales, and bats, among others.
Invertebrate: Invertebrates are animals that do not have a backbone or a spinal column. This group of animals includes a vast number of species, such as insects, spiders, snails, clams, jellyfish, and worms, among others.
Vertebrate: Vertebrates are animals that have a backbone or a spinal column. This group includes mammals, birds, reptiles, amphibians, and fishes.
