Marty’s photo of the day #2875: In this photo, I’m enjoying the company of an octopus, in the Sea of Cortez. If you look closely you can see one of the octopus’s eyes and its siphon (which is what gives it jet propulsion to “fly” through the water). Note how wrinkled my fingers are. Spending time with the octopus was such a special occasion, I lost track of how long I was in the water.
