According to the Hanafi Ulama, the only living creatures of the sea that are permissible are those that are in the form of a fish with an exception of the eel and hagfish, i.e.  although not in the form of a fish, they are permissible to eat.

 

Please, consult your scholar if you are of a different school of thought other thanb a Hanafi.

 

Remember me in your du'aas.

 

Wassalaam Ma'al Ikraam,
