Different Types of Animals
Animals belong to the biological kingdom of Animalia. They are multicellular, eukaryotic organisms. All animals can move in response to their surroundings to find food, look for a mate, escape from danger, or attack other organisms. Animals cannot make their food. They are heterotrophs. They can be secondary consumers (like a fox eating a rabbit) and tertiary consumers (eagle eating the fox). Animals are found in every region of the world. They inhabit areas with extremely different temperatures. Camels can survive as high as 120°F temperature, and penguins live in the coldest regions of Antarctica. There’s still so much we can learn about the different types of animals. Let’s explore further.
Types of animals?
- Vertebrates: These animals have a backbone. They also have muscles and skeletons that help them move around and perform complex functions. Their backbones give their body a rigid shape. Mammals, fishes, reptiles, and birds belong to this subphylum Vertebrata.
- Invertebrates do not have a backbone, so they have a soft, unprotected body. For this reason, they have a covering, called an exoskeleton, around their bodies. They have a wide range of sizes, from small worms to giant coconut crabs.
Mammals have three distinct features. They have hair on their bodies, mammary glands, and three middle ear bones. They are warm-blooded animals and categorized into groups;
- Monotremes: These mammals are different from others in just one thing; they lay eggs, and their offspring hatch out of them. Just like other mammals, their babies feed on their mother's milk. They are ancient mammals and are supposed to have originated from a different line than the other groups. Examples include the duck-billed platypus and the short-billed echidna.
- Marsupials: They give premature birth, and the baby completes the late stages of fetal development in a pouch on its mother's lower belly. It drinks the mother's milk and completes its development in the pouch. The most common example is a Kangaroo.
- Placental mammals: They are characterized by the presence of a placenta, which develops in the gestation period and lets the fetus get nourishment from the mother's body. The baby completes its development there and is given birth when ready. This is the most common type of mammal. Examples include humans, sheep, horses, etc.
Birds have feathers and lay hard-shelled eggs. They are endothermic animals and do not need an external source to maintain their body temperature. They walk on two legs and hence are bipedal. Their bodies are spindle-shaped, and their bones are hollow inside. They have a beak in place of a mouth, and their bodies are covered with feathers. Birds evolved from dinosaurs. Sparrows, ostriches, penguins, and ducks are all examples of birds.
Reptiles are cold-blooded animals and use their environment to regulate body temperature, like lizards basking in the sun. Their skin is thin and covered with rough scales. Most reptiles produce eggs, but some snakes and lizards give birth to live young. Crocodiles and alligators are common examples of reptiles.
Amphibians are cold-blooded vertebrate animals that live on land and water both. They need moisture to survive. Most species are born in water but move to live on land as an adult. But others spend their whole lives in water. Amphibians lay eggs in water and have an aquatic larval and terrestrial adult stage. Their moist skin is responsible for gas exchange, and adult species may or may not have gills. Examples of amphibians are frogs, toads, and salamanders.
Fish are cold-blooded animals that live in fresh or salty water. They have gills that help them breathe underwater and fins for stability and motion. Fish also have scales on their bodies which helps them glide through the water. Most fish lay eggs that are fertilized outside of their bodies. Some fish lay eggs on shore or in plants in the water. For example, goldfish and tuna.
Insects have a hard exoskeleton; their body is composed of three parts; head, thorax, and abdomen. They are the largest group of invertebrates and belong to the class Insecta. Many species of insects undergo metamorphosis, a drastic change in form or structure, e.g., transforming a tadpole into a frog. Insects are found in almost all marine and terrestrial environments, with almost 1 million species. Examples of insects are beetles, ladybugs, and mantis.
