Just down the street from my home is a really amazing set of tide pools. Very popular on the weekends.
Every chance I get when the tides are low, I head down there looking for cool, rare critters. I had always hoped of seeing an octopus.
This is quite a rare sight down there but worth all the effort!
The little blurry spot just above it is where it is "exhaling" water from it's right side up to the surface.
