Vertebrate and Invertebrate animals
Vertebrate and invertebrate animals hmm vertebrates have a particular column or backbone. There are about 62,000 species that belong to this group; some characteristics of vertebrate animals include their muscles and skeletons. They also have an endoskeleton; all vertebrates have some or all of these systems skeletal system, muscular system, excretory system, nervous system, and immune system.

Some mammals include humans, this aquatic mammal dolphin, these tall giraffes, and lovely horses. Amphibians are cold-blooded animals. Some examples are frogs, tiny toads, and these newts now.
Let's learn about the invertebrate animals; invertebrates don't have a backbone, but they make up about 95% of all animal species hmm invertebrates have four common characteristics they don't have a backbone; they reproduce by two reproductive cells.
They are multicellular they have no cell walls some invertebrate animals are aha these eight-legged arthropods spiders insects worms these star-shaped Econo derms sea stars or starfish snails crabs and these lobsters with hard shells.
