They are also predicted to eat nearly 6 million insects, including ants and termites, every month, with no teeth. [75], The nucleic acid sequence of a specific receptor-binding domain of the spike protein belonging to coronaviruses taken from pangolins was found to be a 99% match with SARS coronavirus 2 (SARS-CoV-2), the virus which causes COVID-19 and is responsible for the COVID-19 pandemic. Pangolins have large, protective keratin scales, similar in material to fingernails and toenails, covering their skin; they are the only known mammals with this feature.
