lots of bugs are full of acids and other nasties that eat teeth away and can be harmful to us. Young ones trying spiders and scorpions etc have no fear. I once splatted a daddy long legs the night before going overseas for the first time. Juice got in my eye and my face swelled up like a balloon for 24hrs. imagine what it would do inside you.
flake/school shark is yummy. I like the croc I have eaten as steaks at the Safari Club in tamworth, Elliot the owner/chef cooks game extremely well. in a pie from a servo, not so much, it was ground up in a stewy white sauce and could have been anything.
