Diversity of Bodies & Sizes (but mostly crabs): Crash Course Zoology #3
Thanks to KiwiCo for Supporting PBS. For more information go to https://www.kiwico.com/CrashCourse
Even though animals can look very different on their surface, there are surprising similarities in how they’ve evolved to solve major problems - like how to support and move their bodies. Today, we’ll take a look at the various ways animals can grow, learn how and why some animals evolved to have a head and others evolved to not have a head, and examine the different types of skeletons - from those inside bodies (like our own), to skeletons outside bodies (like in insects), and even those made of water (like in jellyfish). Evolution is a wild journey that brings us so many different animals with a huge array of bodies and sizes - that is, until everything turns into a crab!
