Your videos are really amazing, thank you for sharing this material!
Wonderful video, what do you think about the debate that bivalves do not feel pain?
Fascinating!
wow so bivalves have a labia just like a certain mammalian organ
Do oysters have light sensing organs?

I'm not an expert on this, but to my knowledge adult oysters as we normally think of them (members of Ostreidae) do not have photoreceptor organs (multicellular structures that detect light), but they are probably light sensitive due to scattered light sensitive cells on the mantle edge. But some of their close relatives (Malleidae, hammer oysters, and Isognomonidae) definitely do have photoreceptor organs. A good recent paper reviewing this is Audino et al. 2020, onlinelibrary.wiley.com/doi/10.1111/evo.14050
