Endoskeleton for Dummies

Alright, so "endoskeleton" is kind of a big word, but I'll break it down for you. Think of it like this – when we talk about the skeleton of a person or an animal, we usually think of the bones that we can see on the outside, right? Like our skull, ribs, and spine. But an endoskeleton is actually the internal skeleton of a creature, the framework that gives support and structure to its body. It's like the hidden framework that holds everything together, like the frame of a house that you can't see because it's inside the walls.

So, when we talk about animals with endoskeletons, we're talking about creatures like us, who have their bones and support systems on the inside. This includes things like humans, dogs, cats, and even fish and birds. These creatures rely on their endoskeletons to protect their delicate internal organs and give their bodies the support they need to move and grow.

But there are also creatures with something called an exoskeleton – "exo" meaning outside. These are animals like insects, crabs, and lobsters, who have their hard outer shell on the outside of their bodies, acting as their skeleton. So, when we're talking about endoskeletons, we're talking about the inner framework, and when we're talking about exoskeletons, we're talking about the outer shell that serves the same purpose.

I hope that makes sense! If you have any more questions, feel free to ask. And don't worry, learning these big words takes time and practice, but I know you can do it!
