- If you flip a shark upside down they go into a trance-like state called tonic immobility. It is often used by researches when handling sharks to subdue them.
- Sharks don’t have bones, their skeleton is made of cartilage. They are a type of fish known as elasmobranch, which also includes rays, skates and sawfish.
