Male reproductive cells, often known as sperm or spermatozoa, are generated by most mammals. All sperm are flagellated, or have a whip-like tail, with the exception of nematode worms, decapods (like crayfish), diplopods (like millipedes), and mites. The complex material known as semen is produced by the male reproductive system. Most of the stuff in the fluid is water, plasma, and mucus (a lubricating substance).
