Walking under stars,
We come alive in the night!
- Aaradhna, The Thirst Pt5, Hilltop Hoods
In the right light, some rocks take on the appearance of living things... The mind leaps from incomplete stimuli to identifying a familiar pattern, where none exists. Perhaps a survival mechanism, but it applies to objects we have never seen in real life.

I found that an underhang on the rock had been used by the first people to sharpen stone tools - over an extended period from the look of the indentations. (Note to self: go back,and image the surface looking for other marks.)
Here a pod of dolphins playfully jump through the jaws of another Cetotheriidae Extant.
