Two week old Octopus incella hatchling in a petri fish about 4cm in diameter. See those small brown spots? Those are chromatophores. They are full of pigmented cells that allow it to change color for communication and camouflage. The two shiny black spots are their eyes.
Though growing no more than 20 inches long, the red octopus is a fearsome hunter! With thousands of chemical receptors and millions of texture sensors lining the rims of its suckers, it scours the seafloor in pursuit of shrimp and small crabs.
I went to the Denver museum of nature and science on thursday to see an exhibit on Vikings, and while I was there I looked at an exhibit about earth from the very beginning, to the beginnings of life, to dinosaurs, to where we are now!
and of course there were lots of cephalopods and of course i had to take pictures!
