You have a question that can only be answered by diving into an animal. You look to the museums. The animals are in there. They have what you need.
One role of natural history museums in society is to enable us to carry out anatomical queries such as the one that preceded the dissection of this rough-necked monitor lizard. The question: How does the hyoid morphology vary in Varanidae ?
Fact: Museum specimens are pieces of history. We shouldn't just tear them apart.
The specimen in this photo has it's hide peeled back. When I was finished, I rolled it back over the neck and sewed the edges back together. The specimen was then returned to its storage tank. It appears normal at first glance.

To get what you need, you must find a dissection approach that does minimal damage. Know what you're looking for in the body and contrive a conservative route to it. Then, write a proposal to the collection staff that describes your research initiative and what you plan to do with your hands. Emphasize your commitment to be cautious. It helps to have a visual aid to present to them.
