Diversity of Bodies & Sizes (but mostly crabs): Crash Course Zoology #3

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!
