He ate some. The issue of the abalone is gooey and disolving. The shell fell off the rest of the body. By the time I grab the abalone and pulled it from the anemone, it partially decomposed but does not smell much at all. Becasue of this, I think the decomposition is due to digestive enzymes instead of bacterial breakdow of the flesh.
Other than underside of the foot, the abalone is green. The skin layer is mostly digested as you can see in the picture. The flesh is fuzzy and fragile due to the decomposition.
