They have a thick layer of blubber to keep them warm!
Special adaptations are unique characteristics that help organisms survive in specific environments. They are traits that have evolved to provide a competitive advantage, such as camouflage, specialized body parts for feeding, or unique methods of reproduction. These adaptations allow organisms to thrive in their habitats and improve their chances of survival and reproduction.
the inhabitants could have special adaptations, such as fish have gills that allow them to breathe under water.
its trunk

Squid have some important adaptations that allow it to survive. Some of these would be its ability to squirt ink at predators. Also the long tentacles allow it to swim fairly quickly in water.

the shape of their bodies and fins. Their fins have special shapes and sizes that allow them to move quickly through the water.
I think that dolphins are probably faster than blue whales because dolphins are smaller than whales. Blue whales are MASSIVE and HUGE and they take a really slow time to get from one place to another. Dolphins are much smaller than blue whales, therefore, they're probably faster.
Very light bodies.
