These types of fish alway use MUCUS to cover their body, and to help reduce friction.
Any one or thing swimming in the pool will reduce the amount of free chlorine available in the swimming pool. Dog hair body fats and other impurity's will take up free chlorine in the pool thereby reducing the amount of effective chlorine available. Dogs bring into the pool more contaminants than do humans for AA lot of various reasons.

The peritoneum lines body cavities' inner walls. It covers and protects the hollow organs, which are more fragile than others.it is a thin layer that helps the frog's skin be protected
To help them swim with less fluid resistence, thus with less energy loss, which is one important driving factor in evolution. Streamlined bodies usually cause less turbulance and so are more "aerodynamic" in water or in any other fluid, such as air.
The streamline shape of a fish has lower friction. Also, vortices form from the movement of the tail which save energy when swimming
There is a thick liquid produced in the joint spaces to cushion and reduce friction. This viscous fluid is called synovial fluid.
A car will have aerodynamic features to reduce forces of friction and drag. A sleek body style will help do this.
by applying water on the floor.
To reduce friction. making the body streamlined makes the fluid friction less.
cartilage
Friction between skis and snow may be reduced by waxing the skis. Air friction is reduced by tucking the body into a streamlined position.
friction is a force which opposes the direction of the movement of a certain body. reducing the friction between moving parts will lead to an increase of acceleration or speed of that particularly body.
If you're in competitive swimming, friction will only slow you down, so the answer is no.However, without it, you'll simply fall like a rock to the bottom of the pool or ocean or wherever you're swimming. So if you're just swimming for survival, then it will be desirable.AnswerWhen an object is moving through a fluid, the term is "drag" not friction, and no drag is not desirable which is why swimmers remove all the hair on their bodies. Buoyancy keeps you from sinking not friction; friction is a reaction force.
Water does reduce friction, as the liquid essentially lubricates the surface between the two objects. However, this only applies to affecting other friction. It has its own friction when objects move through a body of water.

The human body must lubricate for intercourse to reduce the friction of genitalia.
