Shark Bay off Australia’s western coast
is home to an amazing diversity of life
including sea snakes sharks and of
course
sea turtles even though they are both
sea turtles the bays greens and
loggerheads are about as similar as
sleek fighter jets and lumbering tanks
despite their hard shells both are on
the menu for the bays top predator the
tiger shark but researchers here want to
know why loggerheads are killed five
times as often as their green cousins is
it just because the loggerheads are
slower to answer that
there’s Crittercam a technology
developed by biologists and engineers at
the National Geographic Society
