The Origins of the Ocean Sunfish

The ocean sunfish, also known as Mola mola, is a peculiar creature that can grow up to 10 feet long and weigh over 5,000 pounds. Despite its size, the ocean sunfish is related to the pufferfish. Its ancestors wandered away from the reefs into the open ocean, where being enormous proved to be an advantage. The ocean sunfish was able to grow to staggering proportions, making it the largest bony fish in the world.

The Ocean Sunfish’s Diet

Oddly enough, the ocean sunfish fuels its growth by eating jellyfish, one of the most calorie-poor creatures in the ocean. Jellyfish are not only low in calories, but they also sting like crazy. To counter this, the ocean sunfish has thick, luscious lips that are coated in mucus. Its intestines are also nice and thick to handle the onslaught of jellyfish.

The Ocean Sunfish’s Reproduction

A mother ocean sunfish will release an astonishing 300 million eggs into the water, a world record for fecundity. These eggs are positively tiny, expanding by 60 million times by the time they’re a full-grown adult.

The Ocean Sunfish and Seagulls

So why are they called sunfish? Well, to rid themselves of parasites that come to the surface and roll over on their side. For one, UV light helps bake the parasites off, while enterprising seagulls land on the fish and pluck off still more. This is an actual use for seagulls, besides carrying the peach in James and the Giant Peach, but that’s fiction, we think.

Conclusion

The ocean sunfish may look like a swimming oddity, but it is a fascinating creature with unique adaptations to its environment. From its origins in the open ocean to its feeding habits and reproductive capabilities, the ocean sunfish is a marvel of nature.
