Call: King of the cavern centipede (Cryptops speleorex
Where it lives: Movile Cave, southeastern Romania
What it consumes: Pests, spiders and smaller sized centipedes
Why it’s remarkable: This fatal, yellow centipede has actually developed to reside in the Movile Cave– a pitch black, sulfurous underground system unblemished by sunshine for more than 5 million years.
Found in 2020, Cryptops speleorex — significance “king of the cave” — sits at the top of the food cycle in the special community. It is the biggest invertebrate types in the cavern, growing to in between 1.8 and 2 inches (46 to 52 millimeters) long.
The centipede has actually adjusted to life in total darkness. Unlike its surface-dwelling cousins, C. speleorex has no eyes. Rather, it depends on other senses to find victim, such as its long antennae that are extremely conscious touch. These antennae assist it spot vibrations and motions of victim in its environment. With its long, spidery legs, the king of the cavern can browse tight areas with ease. The centipede has actually poisonous pincers called forcipules that are developed to capture and paralyze victim once it gets close.
To endure in an environment that has no sunshine– and for that reason no plants that produce energy by means of photosynthesis– the animals in the cavern depend upon nutrients produced by germs through the oxidation of gases like methane and sulfur. This procedure is called chemosynthesis. C. speleorex Consumes other animals in the cavern to get these nutrients.

The king of the cavern likewise needs to compete with the range of lethal gases in its home. The Movile Cave is plentiful in hydrogen sulfide, methane, ammonia and co2, while it has around half the typical level of oxygen in the air outside the system.
It’s not understood precisely how they have actually adjusted to make it through these gases. C. speleorex breathes through spiracles linked to a tracheal system that might have progressed to effectively draw out oxygen in low-oxygen environments.
While some types discovered in the cavern likewise exist beyond it– such as tiny roundworms called nematodes (Nematoda— C. speleorex does not leave its unwelcoming home, according to the scientists who found it.
“Our results confirmed our doubts and revealed that the Movile centipede is morphologically and genetically different, suggesting that it has been evolving from its closest surface-dwelling relative over the course of millions of years into an entirely new taxon that is better adapted to life in the never-ending darkness,” the scientists stated in a declaration at the time.
