This is a sharturtle.   Our job for this project was to create a realistic creature.  I choose a sea turtle, shark head, and a gecko tail.  I had some great feedback from students.  One feedback I received is adding a coral reef.  I thought of doing that but my backstory for my sharturtle is living in the deep sea.  It is not like a regular sea turtle, it does have a shell for protecting itself and a shark head to be the fierce creature of the sea.  The gecko tail can fall off and regrow to save itself from other fierce creatures of the deep sea where the sharturtle lives.
