"My name is Olivia and I am 7 years old. I loved seeing the whales. I liked petting them even more! I am visiting Ojo de Liebre lagoon in Mexico. I learned that baby whales are called pickleheads and I saw why—they look like big black pickles! The baby whales are born black. They turn gray as they get older and get barnacles."
