	I'm looking for some specific information about fish and their fins as part of a small research I'm doing on the subject. I would really appreciate it if you could answer the questions bellow, since I assume you posses a lot of knowledge in that area. 1) Are there are any fish that their fins are not being used for swimming at all? (if there are any, could you please tell me their names?) 2) Does every fish have to have at least one fin, or are there some that got no fins at all? (if there are any, could you please tell me their names too?) Thank you very much.
