Going Further: Grey Nurse Shark Exploration activities
1. Shark sizes: Using a good reference book find out the sizes of different types of sharks. Have students line up and then have different students pace out the length of different species. Compared to other sharks is the Grey Nurse Shark large or small?
2. The teeth of Grey Nurse Shark are quite distinctive. Use the internet to collect pictures of different types of shark jaws. Put these pictures into a table and list next to the jaws the type of food that the shark eats. How many of these are fish eaters like the Grey Nurse Shark?
3. The Grey Nurse Shark was one of the first sharks in the world to be protected. What other sharks around the world are protected and why? What things are done to protect these animals and prevent them from becoming extinct?
