Length of tentacles about 4 inches.
This is the second of this size/species in two days -- small (about 2-3"), sick/nearly dead, like the first one. Is something going on with the octopuses in this area?
Nearly dead, this small (3") octopus was out of water on the reef and showed only the barest signs of life.
Video of this octopus minding its own business: http://youtu.be/KIGRgzW57Vc
Or a great day gets greater, for me, at least. My first time seeing this species in the south.
