I think the gold colored one represents a dugong, manatee, dolfin, whale, or seal, being a mammal but with the head colored green like the water, located in the water, showing that it has taken back to it, possibly to avoid the desert. If this is so then it is a hint that the body of water is a sea, rather than a lake or a pond. To me it is a further expression of the idea that the earth used to be different and explains a bit about the diversity of life in general.

The animal you are mentioning doesn’t have a green head. The green color is from the other side of the folio.
