If you listened carefully, you could almost hear the little green sea turtle squeal with delight as his caretaker gave him a vigorous back rub.
Just like humans, Izzy, as he is affectionately known by employees and volunteers at the Turtle Hospital in Marathon, Fla., loves a good scratch, said Gunnar Zollinger, a biologist with the nonprofit Turtle Hospital, a turtle rescue, rehabilitation and release center in the center of the Florida Keys.
"Greens have thinner shells," Zollinger told the crowd during a recent tour. "They are the only ones that like to be scratched."
