Eels. Eels do not typically have pectoral fins (general area of animalia arms), nor do they have pelvic fins (the general animalia area of legs). Dorsal and anal fins are typically fused along the back around the tail and over the belly with the caudal fin a a ribbon-like structure.

The fins act as stabilizer's. When the snake would make "S" movements in the water it was hard for it not to flip over at some point. So, it has developed fins on its back to works as a stabilizers which help to keep it right-side-up.
Most fish (the ones with gills and fins) are vertebrates.
Yes fish is an organism. A fish is any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in fresh water, with species being known from mountain streams (e.g., char and gudgeon) as well as in the deepest depths of the ocean (e.g., gulpers and anglerfish).
I do not know of any mammal (mammals are the only animals to have hair) that has fins (fins are the preserve of fishes), but a sea-lion is an animal that is covered in hair and has "flippers".
