When blow up larger like this, you can see that the "gorilla" is the same color as the background foliage. That should tell you that this is an excellent example of pareidolia. Also, the gorilla seems to have a large toad hugging a picture of Jesus on its rump. The poor gorilla also seems to have a very large goiter below its neck.
I love pareidolia. More fun than Where's Waldo.
You are interpreting the picture differently to me. thought the lighter horizontal line was it's eyes smudged, and therfore what you call a goitre on it's neck is what I interpreted as the lower part of a gorillas head i.e. face.
