Don't know what the image looks like but typically you could make a copy layered, that copy you tweak the colors until the part you want is heavily contrasted. Using the selection tool you should be able to select and cut the alligator/Crocidile from the layered copy. From here you should be able to capture your image... Or, in GIMP anyways, you can zoom in and using the free form selection tool, zoom in to the edge of your lizard and painstakingly select the border. Once selected you simply right click and find the copy selection option, right click again and paste as a new image. The latter was my go to for most of this kind of work so put on a good movie and be patient if you choose this option.. HIH.

There are some programs (GIMP included) where you can turn a picture
into a line drawing (using less data bits), by adjusting a threshold
where it determines what's blank space and what's imagery. In essence,
turning it what looks like an old fashioned photocopy, or fax scan.
Though, you may not want a simple ink/blank rendition of your image.
