Viscosity is the resistance of a liquid (or any kind of matter) to flow. Honey has a very high viscosity, while water has a very low viscosity. However, water's viscosity is still about 30 times higher than that of air, so a marine mammal's speed is slowed down by the fact that it travels through water, not air. Also, water has about the same density (higher density corresponds to higher viscosity and vice versa) as a marine mammal's body, so a marine mammal could exert almost no energy and stay at about the same depth in the water.

What are animals living in water called?
animals that do not live in water are called mammals unless if it is a dolphin or turtle. amphibian: vertebrates that live life in and out of the water
What adaptations do marine mammals have in order to deal with the cold temperature of the water?
Marine mammals have adaptations such as a thick layer of blubber for insulation, a counter-current heat exchange system to retain body heat, and a low surface area to volume ratio to minimize heat loss. They also have specialized blood circulation that helps in retaining heat in the body.
It is known that all living things must have fresh water to survive. How do any kind of marine animals acquire fresh water if all they have access to is salt water?
Marine animals have different ways of maintaining their water balance. Some marine animals, like fish, have specialized organs that help them excrete excess salt, while actively seeking out sources of fresher water. Others, like marine mammals, obtain water from their food and have efficient kidney functions to conserve water. Some marine invertebrates, like sponges, can filter and pump water to extract nutrients and maintain their water balance.
Do penguins have blubber?
No, penguins do not have blubber. Instead, they have a layer of feathers that insulate them and help regulate their body temperature in the cold water. Blubber is typically found in marine mammals like seals and whales to help them stay warm in cold water.
What is the difference among marine mammals and other mammals?
Marine mammals live and water and they need to surface to breathe. While land mammals can breathe just as humans do.
Where do most marine mammals live?

Fish and some marine mammals live in water all their lives.
How do some marine mammals use sound in water to their advantage?
they use it by listening
Can dolphins breathe air above water or do they have to breathe under water?
No mammals can breathe underwater. All mammals, including sea mammals, must breathe above the surface of the water. This is why marine mammals such as dolphins and whales frequently come to the surface.
What marine life lives in Antarctica?
No marine life live on Antarctica: marine life lives in open water. However, marine birds and marine mammals do visit Antarctica's beaches to breed.
What do you call a doctor who cares for under water mammals?
it's called a marine bioligist.
What are the types of life in water?
Types of life in water include fish, plants, marine mammals, invertebrates, and amphibians.
What is the role of dorsal fat in marine mammals' thermoregulation?
Dorsal fat in marine mammals helps to insulate their bodies and regulate their temperature by providing a layer of blubber that helps them stay warm in cold water.
What is nektonic?
nekton is an organisms that actively swims in the water. Eg Fish, marine mammals and squid.
Is dolphins a fish or a mammal?
a dolphin is a marine mammal that lives in open water in the ocean.
