SHE'S JUST LIKE HER MOTHER!
It was December 2001, and the employees of the shark exhibits at the Henry Doorly Zoo in Omaha, Nebraska, had just discovered that one of their bonnethead sharks had given birth to a female baby bonnethead. They were shocked. For three years, there had been only three bonnethead sharks in the tank in which the baby shark was born. They were all female.
Some female sharks, including bonnetheads, which are related to hammerheads, are known to store sperm for later fertilization. Did this explain how the shark got pregnant? As you read this chapter, look for clues that help explain how the baby bonnethead's mother got pregnant. Also, think about how sharks typically reproduce and the effect of that process on the offspring's genetic material. Then, solve the mystery.
Never Stop Exploring Your World.
Finding the solution to what happened in the shark tank is just the beginning. Take a video field trip with the ecogeeks of Untamed Science to see where the mystery leads.
