A giant pregnant creature of the ocean was in distress after being entangled in a two-inch thick rope.
It's a rare species known as a whale shark, the largest fish in existence.
The rope must have been there for quite some time, because it cut deeply into her flesh. Barnacles actually began growing on it.
Fortunately, a fearless scuba diver was there to come to the whale shark's assistance. He used a dive knife to cut right through the rope.
The drama took place 250 miles off the coast of Mexico.
The sea beast seemed to know instinctively that the diver was there to help. Remarkably, she remained calm even as the rope was every-so-gently unwrapped around her.
Whale sharks have been around for 60 million years, but now there may be as few as 30,000 left in the wild.
The divers were on a vacation when they came across the stricken whale shark. After the rescue mission deemed a success, you can bet that was one appreciative expecting mom.
