Due to the fact that many lizards and amphibians are purely insectivorous I am curious as to whether or not they are able to digest chitin. I have read (in my biochemistry text) that since chitin is similar to cellulose that vertebrates are unable to digest chitin. Yet looking around I have noticed that some studies are being done that show that some sea birds and definitely bacteria can digest chitin. Is there any evidence of a symbiosis with bacteria that allows for digestion of chitin? Is there any evidence of chitinases in the various insectivorous herps? I am just beginning to explore this idea and just wanted to throw it out and see what kind of thoughts are floating around out there. Thanks in advance for you responses.
