      I’ve not heard of any animals that are immune to all diseases. There’s a myth that sharks are immune to disease and cancer, though it’s not true – sharks get diseases and parasites just like us. One of the reasons they are probably thought to be completely immune, is that they produce squalamine – a chemical that seems to be really good at fending off bacteria and viruses.

      Unlikely, even if you vaccinated them against all know infectious diseases it may not stop a genetic disease from killing them.
