The importance of being Aquaman, or how to save the Atlantean from his briny fate

This is an update and repost of our follow-up article on the science of Aquaman, revised and expanded.

Aquaman has an unpleasant lunch. From New 52 Aquaman #1 DC Comics.

Yesterday, I challenged you to consider how the greatest hero in the DC Universe would fair if forced to survive in the real world. The result was a hypothermic, brain-dead lump of jerky with brittle bones, forced to suffer through constant screams of agony even as he consumes sea life at a rate that would impress Galactus. In short, the ocean is a rough place, even for Aquaman.

But this is Southern Fried Science, and we’re not here to trash the greatest comic book hero of all time without offering some solutions, too. I went back to my comic books and my textbooks to assemble an Aquaman with a suite of evolutionary adaptations that would allow a largely humanoid organism to rule the waves, trident triumphantly raised.

Essential assumptions

Many people commented that Aquaman is not human, he is Atlantean, and thus is not bound by human limitations. This is wrong on at least two counts. First, in most iterations, Aquaman is half-human, which means that Atlanteans must be similar enough to humans, both physiologically and evolutionarily, to produce a viable hybrid. While there may be some minor differences between us and the children of Atlantis, functionally speaking, we’re the same. Second, these are not issues that plague only humans. Whales get the bends, amphibians freeze to death, fish need to regulate their internal osmolality. These are the problems inherent in being alive in the ocean, Atlantean or otherwise.

Aquaman. DC Comics. A rational response to seal poaching is to lob a polar bear at the aggressors.

Aquaman may not be everybody’s favorite superhero, but since his creation in 1941, he has been among DC’s most enduring icons. During the Golden Age of comics, he held his own against Superman, Batman, and Wonder Woman. Silver Age Aquaman was a founding member and eventually leader of the Justice League. His powers, tied to the ocean, forced writers to create a compelling, complex hero with explicit limitations. In the early days, when Superman’s strength was practically infinite, and Batman’s brilliance was unmatched, Aquaman had to become more than just a superhero, he had to be a person.

If Superman existed to show us how high the human spirit could fly, and Batman to show us the darkness within even our most noble, Aquaman is here to show us the world that triumphs in our absence. The ocean is not ours, and no matter how great our technology, we will never master it as we have mastered land. Aquaman has. Through this lonely ocean wanderer, we can experience a world that we can never truly command. In many ways, Aquaman was stronger than the Man of Steel and darker than the Dark Knight. He knew loneliness that the orphan and the alien exile never could.

Even though Aquaman had to fight harder, endure the jokes of other, less interesting heroes, and find relevance in an ecosystem hostile to the humans that had to empathize with him, Aquaman was never forced to confront the truly horrifying consequences of life in the ocean.

The penetrating cold

Aquaman is, for all intents and purposes, a marine mammal. With the exception of a healthy mane in later incarnations, he is effectively hairless. As a human, we would expect his internal body temperature to hover around 99°F, or about 37°C. Even at its warmest points, the surface temperature of the ocean around the equator is only about 80°F/27°C. At the poles, ocean temperature can actually drop a few degrees below freezing. In the deep sea, ambient temperature levels out around 2 to 4°C. The ocean is cold, and water is a much better thermal conductor than air. Warm blooded species have evolved many different systems to manage these gradients, including countercurrent heat exchangers, insulating fur, and heavy layers of blubber. This is what a marine mammal that can handle cold waters look like:

Aquaman is not just a human, he is an atypically uninsulated human. If the man has more than 2% body fat, I’d be shocked. In contrast, warm-water bottlenose dolphins have at least 18 to 20% body fat. Anyone who SCUBA dives knows that, even with a 12 millimeter neoprene wet suit, after a few hours in 80°F water, you get cold. Aquaman, lacking any visible insulation, should have slipped into hypothermia sometime early in More Fun Comics #73. He is built for the beach rather than the frigid deep.

Jason Momoa is not a man blessed with an over-abundance of “bioprene”.

Roll on, thou deep and dark blue Ocean – roll!
Ten thousand fleets sweep over thee in vain;
Man marks the earth with ruin – his control
Stops with the shore; — upon the watery plain
The wrecks are all thy deed, not does remain
A shadow of man’s ravage, save his own,
When for a moment, like a drop of rain,
He sinks into thy depths with bubbling groan,
Without a grave, unknell’d, uncoffin’d, and unknown.
