Fat and thin
This picture is stitched in Photoshop - a comparative example of angel fat and hungry. And it is quite tiny assholes, only 2-3mm size, they still have 3 belts of cilia and larval fat droplets that are canned calories in case if they will not succeed in hunting at sea butterflies in the nearest future. Then they will store up these fat droplets from the caught and digested pteropods, and that will be a lot of fat! Angels live on it for a few months, when butterflies will disappear from plankton.
