Belly Button Research

My daughter had to do a presentation on sea turtles for school.

"Mom," she said.  "Come and see my power point slide show."

I stood behind her and watched.  It was really good.  But on one of the screens, it said that turtles had belly buttons.  "Are you sure about that?" I asked.

"Yeah, mom, look!"  She pointed at a little spot on the underside of a baby sea turtle's shell.

"But sea turtles don't have umbilical cords like mammals," I said.

"Yes, they do," she retorted.

"You'd better do a little research on that," I said.

She googled, "Do turtles have belly buttons?"

The answer was, "no."

"See, I told you," I said.

She wouldn't take "no" for an answer.  "Chickens have belly buttons!"  She pulled up a screen of an embryo in an egg, and it looked like it was attached to the yolk via a belly button.  "Turtles are the same!"

Long story short, after additional research we have concluded that turtles really do have belly buttons.  Looks like Mama was wrong again.  Apparently my daughter knows more than me!
