a dorsal fin is the one (or more) located on the back of a fish or aquatic mammal - its the fin that you see when a shark is swimming just under the surface of the water. Ventral fins are the ones toward the rear of the body and help in steering the animal through the water
Fish live in water because their bodies are specially adapted to survive and thrive in aquatic environments. Their gills extract oxygen from the water, allowing them to breathe, and their streamlined bodies and fins help them move swiftly through the water. Additionally, water provides buoyancy to support their bodies, making it easier for them to swim and navigate their surroundings.
Yes, sharks have paired fins, including pectoral fins (located on their sides) and pelvic fins (located on their underside). These fins help sharks with stability, steering, and maneuvering in the water.
The presence of fins on a fossil suggests that the organism likely lived in water at some point in its life. This could indicate that the area where the dig took place was once covered by water or that the organism had adapted to an aquatic environment.
A fish uses its fins for steering, balance, and movement in water. Fins help the fish to navigate, change direction, and maintain stability while swimming through the water.
Animals that use fins to move are whales, dolphins, sharks, and various types of fish. A fin will generate thrust and propel the animal through the water.
If it lived out of the water it would not be aquatic.
Paired fins in aquatic animals help with both movement and balance. They provide support and help the animal steer and change direction in the water. The paired fins work together to propel the animal forward and maintain stability while swimming.

a crab
well the animals sometime get brave and jump in the water or go swimming in the ocean and then if they get bit by a mermaid they get fins like a fish.

A reptile?
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".
Monorhina is an extinct, prehistoric fish like creature which had one single nostril and paired pectoral fins. Monorhina lived in water.
You can call it anything you want!
A water rocket should probably have three to four fins.
