This dataset is composed of mechanical and mineralogical properties of the teeth of Port Jackson sharks, Heterodontus portusjacksoni, which have been exposed to ocean acidification and warming for about six months in the laboratory. Mechanical properties include hardness, elastic modulus, mechanical resilience and tooth damage, whereas mineralogical properties include mineral composition and crystallinity. These data show that sharks can adjust their tooth properties in response to climate change.
