Re: gums



That would appear to be standard for goannas generally. Goannas (or
varanids) generally are not a "toothy" creature. The teeth are the primary
eating tool (along with various necrotising bacteria in the larger ones like
Goulds, Perentie and the Nile - not to mention tne Komodo), but they are not
a 'threat' device as with, say, crocs. Their mouths are generally a pale
colour and the gaping is done to frighten off intruders with the display of
"aberrent" sickly colouring and hissing. The claws are FAR more lethal to
non-prey victims (like people). Generally, when goannas 'bluff' the teeth
are all but invisible. A great rendition of Megalania adorns the dust cover
of "Wildlife of Gondwana" by Tom Rich and Pat Vickers-Rich.
