How do sharks work? Learn how to dissect a dogfish shark in this video, which also covers its external and internal anatomy and physiology. In this simple dissection of a shark, you’ll learn various parts of the cartilaginous fish anatomy, why shark skin feels like sandpaper, and why sharks need to swim continuously.


Sharks, despite their reputation, don’t pose much of a threat to humans, and there’s a lot to learn from their anatomy. They are part of a group called cartilaginous fish, and their body plan and anatomy are fascinating in that it evolved hundreds of millions of years ago without much change. In this video, you’ll learn general information about sharks, which will be tied into its anatomical structures.
