Why the aversion to eating terrestrial invertebrates in western cultures?

Nope Motog I don’t like oysters!! They feel like a big glob of snot sliding down your throat and they taste much like a teaspoon of seawater. That’s natural (uncooked), I can imagine eating them cooked but have never had them like that.

On the other hand, I could eat mussles/prawns/crayfish (especially crayfish) till the fat cows sing their way home!
