Crocodillin is an
antibacterial substance found in
crocodile blood. The active component is a protein made of amino acids called a
peptide. As a part of the immune system, the string of peptides fights bacteria and enables crocodiles to avoid serious infection in the very septic and contagious environment that they reside in.
