Marty’s photo of the day #2051: Of the many cool things about octopuses, that they can change colors and textures ranks near the top of the list. In this photo, Deb is holding an octopus underwater. Note the unusual texture of this octopus. Earlier this month, I posted a picture (photo #2035) of Deb holding this same octopus above-water. In that photo the octopus looked much smoother—and totally limp.
