Animals can be classified into different groups that share common characteristics. The two main groups of animals are Vertebrates and Invertebrates.
Watch this video to learn more about them:
VERTEBRATES are animals that have a spinal cord or backbone. They can be further classified into five groups or classes: fish, amphibians, reptiles, mammals and birds.
Watch these videos to learn more about vertebrates and their classification:
Most of the animals in the world are INVERTEBRATES. These animals do not have a spinal cord or backbone. Most invertebrates are oviparous, and we classify them into six main big groups: Porifera (sponges), Cnidarians (jellyfish and corals, previously called Coelenterates), Annelids (segmented worms), Molluscs, Echinoderms and Arthropods.

The largest animal group on the planet is ARTHROPODS.
Remember these animals are a group of invertebrates. All arthropods have jointed legs. Another fascinating characteristic that they all have in common is that their body is divided into segments, and many of which, though not all, are protected by an external skeleton or exoskeleton that is used as a shield or shell. Some arthropods bodies do not grow at the same rate as their exoskeleton, therefore making them shed it for a bigger size, a process known as molting.
Here you have a video to learn more about these amazing group of animals, which includes insects (6 legs, ants and butterflies), arachnids (8 legs, spiders and scorpions), crustaceans (10 legs, crabs and shrimp) and myriapods (more than 10 legs, centipedes)
