Scientists in Australia tagged a healthy 9-foot great white
shark as part of program to
track these animals. Four
months later they found the
tracking device washed up on a beach. Something—
something really big—had
eaten this apex predator. But
what creature could dine on
such ferocious prey? The recovered device showed
a rapid temperature rise and a sudden 1,900-foot change in depth. That's all the
information the scientists have.
