In less than five minutes, you managed to cover a fascinating topic in an interesting way, move from that topic into the scientific potential for humans, steer the topic into the environmental impact we're having on the subject, then toss several iterations of that same message to the audience and end with a signal boost for charity. That was EPIC.
Octopuses are a favorite topic of mine. I remember doing presentations about them in college before we knew about the photoreceptive skin thing. That was so exciting to hear about when it made the news.
I dont think that us not knowing everything about the ocean is is one of the main tragedies though, i think it is more so that as nature it should inherently be allowed to live, not because it could help us, but because life deserves to be able to live
FYI as of this comment the special fundraiser tag isn't working on your video, when setup correctly it will get a card on the right of the dooblydoo for the fundraiser.
So it has been suggested that cephalopods may be able to discriminate colour by taking advantage of chromatic aberration, the different refraction of different colours/wavelengths of light as they pass through a medium like the lens of an eye. I read about that somewhere and half forgot the details and just searched to find them again. Also quickly reading stuff when I googled that to remind myself of the details apparently against the idea that there skin receptors match colours is that they only seem to have one kind of photoreceptor in their skin so that should not discriminate colour either. The thing I remember about cephalopods is that their eyes have no blind spot, unlike our eyes. Suggesting that instead of being cobbled together by accident like our eyes there eyes probably originated from the design of some cold alien intelligence. ;)
