National Geographic has released this soon-to-be classic photograph of one shark eating another shark whole.

The photo comes from Daniela Ceccarelli, of Australia's Research Council Center of Excellence for Coral Reef Studies. Ceccarelli was working with fellow researcher David Williamson on conducting a "fish census" off Great Keppel Island, part of the country's Great Barrier Reef. That's when Ceccarelli spotted a brown-banded bamboo shark hanging out near the ocean's floor.

As the New Scientist explains Wobbegongs, aka carpet sharks, are silent predators, waiting at the bottom of the ocean floor for their pray to pass by.
