Visual Library Studies: Bats Cont’d & Cold Blooded Critters

Continuing my visual library building and painting practice, I took this flying fox sketch from last week and painted over it based on a photo ref.  It took some time to capture the translucency of its wings in the daylight.

I was excited to move on from the mammal studies for now, as I’ve covered many common mammal groups.  This week I focused on reptiles, trying to capture three major groups of them with my studies: the lizards, crocodilians, and turtles.  I decided to save snakes for another time since they are so unique in their body structure.

Green Iguana One thing I observed in all three reptile groups was the hip bone configuration: the legs are splayed out to the side, causing them to move from side to side as they walk.  This differentiates reptiles from dinosaurs, who have more birdlike hips that allow them to get their feet under them and move in a straight line with less wasted movement.

Saltwater Crocodile Built quite similarly to lizards, but with extremely powerful jaws and tails.

Green Sea Turtle Turtles had the most difficult skeletons to study, since their shells are fused to their ribs and obscured the view of other bones.  However, I could see the similarities between them and other reptiles in their basic skeletal structure.
