This deep sea fish is aptly called the Great Swallower, and it certainly lived up to its name with its last meal.  Taking on a Snake Mackerel four times bigger than itself, you can't help but admire its chutzpah, even if it did kill him. 

The two fish were found off the south coast of Grand Cayman, and  the fisherman who found them tells the full story at the Cayman Free Press.
