Certain types of critters it's best to just harvest the part with the most meat and discard the rest.
Frogs: very light & tasty meat, skin the legs and discard everything else.
Squirrels: Only real meat is in the legs and loins (lower back), skin and discard the remainder.
Pigeons, Quail, & other small birds: Just take the breasts, hearts, & gizzards and discard everything else. You don't even have to pluck them, just cut the meaty portions out and skin them. Black birds are small; that's why it took 4 and 20 to make a pie.
Sea Cucumbers: Just use the ring mussels and discard the rest.
and the list goes on....
If Turkeys had breasts the same size as racing pigeons for their overall size they would have twice the meat they have now.
Also there is how you fix it. The sculpin, a fish that eats crabs, will taste like crab if you steam it but like fish if you fry or bake it. Skate wings, if steamed, taste like scallops. Butter clams, if eaten raw, taste buttery--hence the name.
