Sea Dragons are incredibly strange creatures, and we may finally know why

Spotting a wispy sea dragon, floating amongst the seaweed, embellished with leaf-like adornments ruffling in swaying ocean currents, is truly a sight to behold.

But there is more to sea dragons than meets the diver's eye. Bedazzled as they may be, sea dragons are also missing teeth, lacking ribs, and their spines are curved and kinked.

Now, scientists have found genetic clues that might explain why sea dragons appear so strikingly distinctive – not only are their genomes packed with repetitive chunks of DNA that drive evolution, but they are also missing a group of genes that give rise to teeth, nerves, and facial features in other animals.

The study was published in PNAS.

  • The title was changed to Sea Dragons are incredibly strange creatures, and we may finally know why
 

Isn't interesting how countless species on Earth have a camouflage appearance? Blending with their environment, to full the predators. What does this say about the whole concept of Life on this exact Planet? I wonder, if on other planets in other Systems and Galaxies creatures can exist without having to blend with the environment out of fear?
