Any animal with a backbone is a vertebrate. Vertebrates includes fish, amphibians, reptiles, birds, and mammals, including humans, and birds. Vertebrates have some fundamental similarities. Most animals have a hollow backbone and a skull to protect their spinal cord and brain. The earliest known vertebrates are fish. Fish often have a bony skeleton. However, the skeleton of sharks and rays is comprised of cartilage, a robust and flexible tissue. The most sophisticated group of vertebrates are mammals. They have hair, develop inside their mothers' bodies, and nourish their young with breast milk. They are more clever than other types of animals due to their highly developed brains.
An invertebrate is a creature without a backbone. In fact, invertebrates lack all skeletal structures. Spiders, worms, snails, lobsters, and butterflies are a few examples of invertebrates that you might be familiar with. Invertebrates make up 97 percent of all creatures in the world. This indicates that just 3% of all creatures are vertebrates. Invertebrates are the most numerous and abundant group of animals on earth, and they are also crucial to a balanced ecosystem. Their "ecosystem services" guarantee the creation of food, medications, and vital environmental material degradation.
Many plants wouldn't be able to reproduce without the help of bees, butterflies, beetles, and other invertebrate pollinators, and people wouldn't have access to many vital food sources. Many animals depend on invertebrates as a major source of food. They have a crucial position at the base of the food chain, where their survival depends on the survival of all other creatures. As an example, spiders eat insects, which are subsequently eaten by birds, which are then devoured by larger predators including lizards, snakes, foxes, and bobcats. The entire system fails if the lowest link in the food chain does not supply nutrients to those higher up the chain.
