Crocodiles are reptiles, and have tough, rough, and scaly.  They also have long, powerful tails and short, strong legs.  The long, powerful tail is the cause that produces the effect of being able to swim very fast through water.

The short, strong legs allow them to travel quickly on land as well.  So, the legs are the cause and quick travel is the effect.  Also, they have clear eyelids so they can see while protecting their eyes from the water.  The clear eyelids are the cause and the protection is the effect.
