[quote=SUMMERSNOW,273414]No.3 Bonnethead shark Females of this small hammerhead shark species were thought to mate with several males and store their sperm for later use, so scientists assumed the resulting litter of baby sharks would have several different fathers. It was thus a surprise when studies revealed most litters are sired by the sperm of just one father. The finding suggests the females are either *ually monogamous, mating with only a single male, or that they mate with many males but that the sperm of one out-competes the others. [/quote]
