Animals are often sorted into 6 distinct groups or types. Each type is extremely unique, displaying different adaptations that enable it to flourish in various environments.
Amphibians are a class of cold-blooded vertebrates that include frogs, toads, salamanders, and newts. They typically have a dual life, with their early stages spent in water and adulthood on land. Amphibians undergo metamorphosis, transforming from a larval stage with gills to an adult stage with lungs. This unique life cycle allows them to exploit both aquatic and terrestrial habitats.
Amphibians are known for their permeable skin, which can absorb water and oxygen, making them highly sensitive to environmental changes. Their skin also secretes mucus and, in some species, toxins to deter predators. Amphibians play a crucial role in ecosystems as predators and prey, helping control insect populations and serving as food for larger animals. Unfortunately, many amphibian species are threatened by habitat loss, pollution, climate change, and disease.

Birds are a group of warm-blooded vertebrates characterized by feathers, beaks without teeth, and the laying of hard-shelled eggs. They belong to the class Aves and are found in virtually every habitat on Earth, from forests and deserts to oceans and polar regions. Birds have a highly efficient respiratory system and lightweight bones, which support their ability to fly, though some species are flightless. With over 10,000 species, birds display various sizes, colors, and behaviors.
One of the defining features of birds is their ability to communicate through songs and calls, which play important roles in mating and territory defense. Depending on the species and habitat, birds' diets vary widely, from nectar and seeds to fish and small mammals. Birds are also known for their migratory behaviors, with some species traveling thousands of miles between breeding and wintering grounds. Their evolutionary adaptations, such as keen eyesight and specialized beaks, contribute to their success in diverse ecosystems.

Fish are a diverse group of cold-blooded vertebrates living in water and breathing using gills. They are found in freshwater and saltwater environments, from deep ocean trenches to shallow streams. Most fish have streamlined bodies, fins for movement, and scales for protection. With over 30,000 species, fish are the largest group of vertebrates in terms of species diversity.
Fish play a crucial role in aquatic ecosystems, serving as predators and prey in food webs. They exhibit various behaviors and adaptations, such as schooling for protection and specialized mouths for feeding. Some species, like salmon, are known for their remarkable migratory journeys between freshwater and saltwater. Fish are also an essential resource for humans, providing food, economic value, and recreational opportunities.

Invertebrates are animals that lack a backbone or vertebral column, making up approximately 97% of all animal species on Earth. They encompass many organisms, including insects, arachnids, mollusks, crustaceans, and echinoderms. Invertebrates can be found in virtually every habitat, from deep ocean floors to arid deserts and tropical rainforests. Their body structures and functions vary greatly; some have hard exoskeletons for protection, while others rely on soft, flexible bodies.
These animals play vital roles in ecosystems, contributing to pollination and decomposition and serving as food sources for other animals. Invertebrates exhibit various behaviors, from complex social structures in ants and bees to solitary lifestyles. Some, like jellyfish, have simple nervous systems, while others, such as octopuses, are known for their intelligence and problem-solving abilities. Due to their diversity and adaptability, invertebrates have thrived in nearly every environment on Earth.

Mammals are a class of warm-blooded vertebrates characterized by hair or fur, three middle ear bones, and mammary glands that produce milk to feed their young. They are found in diverse environments, from the deepest oceans to the highest mountains. Mammals have complex brain structures that contribute to their advanced behaviors and social interactions. Most mammals give birth to live young, though some, like the platypus and echidna, lay eggs.
Mammals play essential roles in ecosystems as predators, prey, and herbivores, contributing to the balance of food chains. They have various adaptations, such as specialized teeth for different diets and the ability to regulate body temperature. Some mammals, like bats, can fly, while others, such as whales, have adapted to life entirely in the water. With around 6,400 species, mammals display a wide range of sizes, from tiny shrews to massive elephants.

Reptiles are a class of cold-blooded vertebrates that include snakes, lizards, turtles, and crocodilians. They are characterized by their dry, scaly skin, which helps prevent water loss and allows them to thrive in various habitats, from deserts to rainforests. Most reptiles lay eggs, though some species give birth to live young. Reptiles rely on external heat sources to regulate their body temperature, often basking in the sun or seeking shade to cool down.
Reptiles play significant roles in ecosystems as predators and prey in various food chains. They have developed numerous adaptations for survival, such as the ability to shed skin, venom for defense or hunting, and camouflage for avoiding predators. Some reptiles, like crocodiles, have remained relatively unchanged for millions of years, demonstrating their evolutionary success. Despite being less diverse than other animal groups, reptiles are found on every continent except Antarctica.
