Yes, all fish do have fins to help them swim. But some have very small fins, and some marine animals such as snakes and eels may not have true fins. Most fish have prominent fins at the end of their tails to guide them, as well as dorsal fins on their backs.
There are two Dorsal fins on a perch. The anterior and posterior Dorsal fins.
Porpoises have triangular dorsal fins (as opposed to the curved dorsal fins of dolphins and whales). Some species of porpoise have small bumps on their fins, but the purpose of these bumps is unknown.
The ones in pairs are: pelvic fins and pectoral fins.
Sharks have straight dorsal fins, dolphins have curved dorsal fins and whales don't have dorsal fins :)

dorsal fins
Eels do not have webbed feet. They are aquatic animals with elongated, finned bodies designed for swimming efficiently in water. Instead of feet, eels have pectoral and dorsal fins that help them navigate their environments. Their anatomy is adapted to life in the water rather than on land.
Shark dorsal fins are typically straight and rigid, while dolphin dorsal fins are curved or falcate. This difference in dorsal fin shape is one of the visual cues you can use to differentiate between sharks and dolphins in the wild.
Yes.Electric eels do have fin.Their fins help them move about through water (swim).
eels do not have legs only fins
