pasta with white shrimps

I ate pasta with shiro-ebi(small white shrimps), green olives, maitake mushrooms tonight. the taste wasn't bad, but I should've gotten the shell off. shiro-ebi is little bigger than sakura-ebi(tiny shrimps in Japan), so that I can eat it with the shell. Actually, I can eat it, but I feel uneasy little. those small shrimps tasted nice, even though it's small.
