Assalaamu Alaykum Wa Rahmatullaahi Wa Barakaatuhu
From seafood, only fish is made Halaal for us. Rasulullah (Sallallaahu Alayhi Wasallam) said, ‘Two carions are made Halaal for us; Fish and locust.’ (Mishkaat vol.2 pg.361). Fish is classified as a Vertebra.
Shrimps are not vertebras, hence, not permissible.
