Well, theres a ton of seafood I eat, that are kind of... dont look at it type stuff. Clams and such are pretty slimy, especially oyster. When I was young, I always thought of squid as bait, till an italian guy came around and showed how to cook them. Things like headfish look like something alien. (monkfish is considerd poor mans lobster) But 2/3 of them are one big ugly mouth. (they never sell whole, just the small tail section making them look like a much smaller fish) I have even tried whale and porpoise in european countries. Whale is pretty oily, usually reserved for cold climates where oil/fat is craved. Porpoise, being a mammal is a red meat kind of like a fishy tasting gamey goat or sheep.
Ive had racoon, possum, porcupine, turtle, gator and more. I'll try anything... Just dont try to fool me, tell me what it is. There are some things like ducks that can taste totally different depending on season and diet. Could taste good one time, and like mud the next, so you cant really just write something off after one try
