no fur + shape of the body -> less friction with water -> less effort needed to move forward
forelimbs -> 'peddals' to increase surface -> push forward move effectively in water
backlimbs -> joined -> horizontal peddal
Sperm cells are able to swim once they have been ejaculated into the female reproductive tract. The environment and chemical cues in the female reproductive tract trigger the sperm cells to become motile and begin swimming towards the egg.
Sperm cells need a tail to swim to the egg for fertilization, as they are motile cells. Egg cells, on the other hand, are non-motile and stationary within the female reproductive system, waiting to be fertilized. This is why sperm cells have evolved to have a tail for movement, while egg cells do not require this adaptation.

Moles are not adapted for swimming and are not proficient swimmers. They are well-adapted for burrowing and living underground in soil. If they find themselves in water, they may be able to paddle or float for short distances but swimming is not a natural behavior for them.
