My Life Underwater

Hey Elasmo! My name is Nosey.

How come you can live underwater, but me and my land friends can't? As much as we try, we can only stay down for a little while!

Speech Bubble
Nosey - you can swim on the surface, but not breathe underwater. I will explain how sharks are better suited to life underwater than you are!
Speech Bubble
It's you who adapted to live OUTSIDE of water. If you saw my last adventure, you might remember that it was the ocean creatures that came first!
Speech Bubble
Are sharks fish?
All sharks are fish, but not all fish are sharks!
Speech Bubble
Speech Bubble
Most fish are made of rigid bones. I'm an elasmobranch - my skeleton is made of cartilage, instead of bones. Cartilage is so flexible that I can touch my own tail!
Speech Bubble
Tell me more! This is amazing!

Activity:
Humans have cartilage in their ears. Hold your ears and give them a wiggle - they should be bendy, but very strong!
Speech Bubble
Tell me more! How do you get oxygen from water?
All fish have gills. It may be easier to show you some pictures!
Thought Bubble
Boney fish have a pair of covered gills instead of lungs, but most sharks have 5 pairs of gill openings, and some even have 6 or 7!
