I almost missed this series. I heard the Alligator with the crab, actually there were several at the same time.
When I tried to get some images he was facing away from me, I had the back of his head. This being a marsh, water, and such my logical options were limited. I walked down the dike angling to get a much of a profile as possible.
I did manage to get these.
The alligator has his tail, and back arched, in a position called ‘profiling’. The gator is showing his intention to keep his catch with body language. Alligators will profile to attract a mate or make a territorial challenge.

There were a large number of alligators around so profiling was happening all morning.
