Nope. Technically, sushi refers to the sticky/vinegar rice that it's usually prepared with - not so much the contents. You can get it regular (rice outside) or inside-out (seaweed outside).
Bugs don't bother me. I remember in survival training we were eating live ants where the trick was to pinch their heads off right before you ate them so they wouldn't crawl back up your throat if you didn't chew them enough... They were actually much tastier than I thought they would be... or maybe it was because we had already gone so long with no food that anything would have tasted good... But the worst taste I remember was slices of abalone, the taste was exactly like what I remembered smelling when I walk by a trash can at a beach where people have cleaned their fish... I tried to choke it down but it wasn't going down no matter what.
cooked crab, by the way... either that or surimi (fake crab sticks)
I quite like cucumber and burdock. One of our locals has a good selection of vegetarian sushi. Their version of the California roll is inside out and has crab, avocado, and cucumber.
Given some people like abalone I will hope that it was just a bad piece in my case, but after it don't think I could ever even try it again to see.
