Five more marine organisms that put their superhero counterparts to shame

Evolution is the most creative force on the planet. Everywhere we look, we find species with novel and phenomenal adaptations that put their comic book brethren to shame. In no ecosystem is this more apparent than in the vast and unfathomable ocean. Marine species, especially those in the deep sea, have evolved to survive in a environment that is completely alien to us. Several months ago, I unveiled “Five organisms with real super powers that rival their comic book counterparts“, but that was just the beginning. Without further adieu, I give you 5 more marine organisms that put their superhero counterparts to shame (and one bonus critter).

The blind shrimp with super senses

Rimicaris exoculata – http://eol.org/data_objects/13231836

In the deep sea, eyes are not among the most useful sense organs. While many deep-sea species have extremely reduced eyes, some have abandoned these organs entirely. Rimicaris exoculata is a shrimp endemic to deep-sea hydrothermal vents in the mid-Atlantic that is completely eyeless. Its carapace is smooth, without even a hint of reduced, vestigial eyes. This, unfortunately, is a problem because Rimicaris exoculata is a farmer. The blind shrimp grows bacteria in its gill chamber, bacteria that can convert the chemical-rich hydrothermal vent fluid into food for the shrimp.

For lack of a more descriptive adjective, hydrothermal vents are hot. Some can exceed 400°C. Rimicaris exoculata needs to get close to this hot vent fluid to feed its crop of bacteria, but not so close as to become a hydrothermal hors d’oeuvre. And so, the blind shrimp evolved a completely new light-sensitive organ mounted on the top of its carapace–the rhodopsin-rich dorsal eyespot.

The dorsal eyespot of Rimicaris exoculata doesn’t “see” in the normal sense, there is still almost no light in the deep sea. Rather, this shrimp is adapted to detect the black body radiation emitted by the hydrothermal vent. For Rimicaris exoculata, the deep sea glows with the light of super-heated hydrothermal fluid, allowing it to both find food for its bacterial crop and avoid getting cooked itself.

It should be no surprise that Rimicaris exoculata is undoubtedly the favorite deep sea organism of another blind champion with super senses–Daredevil.

The horrifying physiological and psychological consequences of being Aquaman

Aquaman. DC Comics.

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 comic books, he held his own against Superman, Batman, and Wonder Woman. Silver Age Aquaman was a founding member 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, but 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.

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.

Byron

Even though Aquaman had to fight harder, endure the jokes of other, less limited 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.
