Very interesting. I don't understand why it mentions this to be a brand new discovery, since the presence of opsins in the skin of animals for mimetism has been known for some time, e.g.

- djmips 3y agoIt seems that the article you reference is more speculating but the article posted is much further along with some results.
- dekhn 3y agoI believe there is some more recent work on this, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4448664/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4448664/ """LACE (light-activated chromophore expansion) in isolated preparations suggests that octopus skin is intrinsically light sensitive and that this dispersed light sense might contribute to their unique and novel patterning abilities. Finally, our data suggest that a common molecular mechanism for light detection in eyes may have been co-opted for light sensing in octopus skin and then used for LACE.""" another, more recent paper, which is more of a review: https://www.cell.com/current-biology/pdf/S0960-9822(22)00659-5.pdf https://www.cell.com/current-biology/pdf/S0960-9822(22)00659...
- wolverine876 3y agoThe discovery in the OP is of dermal photoreception in a vertabrate.
- rob74 3y ago...plus it covers a whole different type of animal (cephalopod vs. fish)
- bolangi 3y agoArticle says it's the first case of opsins found in the skin of a vertebrate.
