Most fish in the ocean or sea have the same body shape. These are tuna, sharks, marlins, mackerel and other species that spend a lot of time swimming.

This is explained by the fact that water is about 800 times denser than air. It’s also more sticky. This means that more energy is needed to move through the water.

The shape of the fish, called fusiform, allows it to cut through the water with minimal resistance. Also, dolphins are considered the best energy-saving form for whales.

Another component of the fish body is the fins. They can be very different depending on their swimming characteristics. For example, tuna and other fast fish tend to have a forked or crescent-shaped tail. This allows them to cover long distances faster and be more durable.
