“It is my hope that we can use our scientific findings about their lives not only to enhance human knowledge, as valuable as that is, but also to honor who these animals are—individuals as intensely wedded to this glorious life as we are, whose lives are as meaningful and significant, in their way, as our own.”
"..I believe we are at the beginning of a similar revolution. We are realizing that humans are not the only beings with sophisticated minds.
Demonstrations of cognitive and emotional sophistication are all around us, even in the most unexpected characters. This monumental shift in perspective provides a radically new understanding of diverse animal minds, not only helping to reshape the way we think about animals, such as the octopus, but also the way we treat them.
The more we reveal the octopus’s secrets, the more empathy and compassion we can feel, which in turn fuels a need to protect these enigmatic critters and their fragile ecosystems. Secrets of the Octopus is the perfect guide through this transformative journey."
"The light-sensitive cells in the octopus retina contain only one pigment. Ours have three; dogs, two. Researchers believe that octopuses must use entirely different systems from our own to perceive and match the colors of their complex world. Octopuses’ electric skin, along with the chromatophores and the nerves erecting the papilla, contain proteins normally found in eyes. In 2015, evolutionary biologists at the University of California, Santa Barbara, working with patches of skin harvested from California two-spot octopuses (Octopus bimaculoides), reported that the skin is sensitive to light and can detect changes in brightness. In other words, octopuses may be able to feel light—or see with their skin."
