Have you eaten anything with an exoskeleton? Land bug, sea bug, same fucking thing. And before some genius waddles in here and tells me sea bugs and land bugs aren't the same...yes they are. They ALL belong to the phylum Arthropoda.
Bugs have been part of our diet since the day we could fucking CHEW. Does that mean we should eat anything with a exoskeleton? Sure, no. There's a lot of shit crawling around on the sea floor, and we eat mostly shrimp, crab, and lobster....the rest we NOPE out on.
There's a reason why we don't eat land bugs is because they are inedible, not because we are all dainty daisies who faint at the sight of bug eyes staring back at us as we chow down on them.
Go steam a cockroach and a shrimp and tell me which one smells more appetizing.
