Sperm with hooks!! I guess make sense when we say: hookup. These are not from the movie alien, they are from a rat. Sperm come in all different shapes and sizes in different species. The differential in sizes and shapes have evolutionary significance. Taken with LabCam on a microscope with Differential Interference Contrast (DIC).
