Where should the line be drawn regarding the status of animals as moral objects/entities? E.G Do you think it is ethical to boil lobsters alive? It seems to me there is a full spectrum of possible answers: at one extreme only humans are valued, or only primates, only mammals, only veterbrates, or at the other extreme, any organism with even a rudimentary nervous system (or any computational, digital isomorphism thereof), could be seen as a moral object/entity.

Now this is not necessarily a binary distinction, if shrimp have intrinsic moral value it does not follow that they must have a equal value to humans or other 'higher' animals. As I see it, there are two possibilities; either we come to a point where the moral value drops to zero, or else we decide that entities approach zero to some arbitrary limit: e.g. a c. elegans roundworm with its 300 neurons might have a 'hedonic coefficient' of 3x10^-9. I personally favor the former, the latter just seems absurd to me, but I am open to arguments or any comments/criticisms.
