Animal body coverings are not just surfaces. They are working parts of the body that help animals stay protected, move through their surroundings, control temperature, sense danger, and communicate. Scales, feathers, shells, and skin all sit at the boundary between an animal and the outside world, but they do not work the same way. The … Read more
Exoskeletons are hard outer body coverings that support and protect many animals, especially arthropods such as insects, spiders, crabs, lobsters, shrimp, scorpions, centipedes, and millipedes.

They can look unrelated at first glance, but they all show the same bigger pattern: the end of the foot is shaped by what an animal needs to do every day. The quick … Read more

The quick difference is simple: antlers are usually branched bones that grow from the deer family and are commonly shed and regrown each year, while true horns have a bony … Read more
Animal anatomy is the study of the body parts that let animals live, move, feed, sense danger, find mates, raise young, and survive in their surroundings. A beaver’s chisel-like front teeth, an alligator’s armored skin, a red panda’s bushy tail, and a bird’s feathers all look different, but they share the same basic idea: body … Read more
