Question of the Week / Re: QotW - 19.10.14 - Are most animals edible? Would the dinosaurs be edible?« on: Yesterday at 08:36:42 »
Animal that don't want to be made into meals may spend resources creating toxic substances to deter hungry animals. Toads, some ants, blow-fish, and so forth.
Indeed. I had left out the first part of the OP's question in my first response.
I think a greater percentage of animals are edible than plants because animals can defend themselves by being fast, or strong, or smart.
Plants and fungi and bacteria defend themselves with chemical weapons.
Most of the edible plants we eat are parts that the plants "want" us to eat--like fruits, or they have been selectively bred by humans for millennia (or, like tapioca/yuca/manioc/cassava, we just boil the heck out of it to destroy the toxins...)
