A new study led by a researcher from Duke University has spotted female sand tiger sharks returning to the same shipwrecks, sometimes over months or even years. Are they taking a rest stop on their migration routes? Are they mating there - like a pirate-themed make-out spot for sharks? Plus: sand sculpture artisans are returning this weekend to Port Aransas, Texas, for the Texas SandFest.
