SCARY, BRAINLESS, AND BEAUTIFUL

Jellyfish in the South Pacific Ocean have adapted to change color depending on their surroundings. These photographs showcase a few of the possible colors they become in order to blend with their surroundings.

The Jellyfish At Sea

One species of jellyfish, known as the Chameleon Jellyfish, has the ability to change in color from hues of blue, yellow, and purple, to blend in with the surroundings. This adaptation strategy allows them to evade predators and catch prey more efficiently. The chameleon jellyfish accomplishes this color change through a complex process involving the pigments in its body and the reflection of light.

Bioluminescence

Another species of jellyfish, known as the Lightning Jellyfish, use bioluminescence to ward off predators. They have tiny lightproducing organs, called photocytes that emit flashes of light when threatened. This adaptation not only scares off predators, but also attracts other organisms that feed on and accompany the predator, providing an extra layer of protection.

Regeneration

Jellyfish are also able to adapt to changing ocean conditions. In the past when ocean temperatures rose and oxygen levels decreased, jellyfish evolved to thrive in these harsh conditions. These jellyfish have larger bodies and thicker tissues, allowing them to exude more energy and survive in low-oxygen environments. They also have been found to have incredible regenerative abilities. When damaged, jellyfish can regenerate their tissues, tentacles, and even their entire bodies. This adaptation allows them to quickly recover from injuries and continue to thrive.

The picturesque landscapes of today show the direct effect that hundreds of years of oil mining has on our environments. What scientist are still trying to wrap their heads around is how these animals have adapted to these living conditions and how their behaviors have transformed to survive.
