Caleidoscope - A world of many colors

Finally he had arrived at the research station. Up here he would be conducting his research from now on. He had been looking forward to it quite a lot. An unexplored world, full of water and hardly any landmass sticking out. Who knew what new lifeforms he would discover over here? Would they have evolved similarly to Earth's sealife, or that of Europe?
One thing was for sure. He would finally get a detailed study of how life adapts to more harmful solar radiation. The nearby star, named after the telescope array used to discover it, emits far more infrared radiation than Sol, Earth's own sun. Trappist, which was the telescope array's name, and thus this sun's name as well, was an acronym referencing some kind of ancient beverage.
Now the sun was named Trappist and each of it's planets had it's nametag in the catalogue as Trappist and then a letter from the alphabet. Most scientists don't believe this planet (was it d, or watnot), is able to support life, due to the high and deadly radiation of it's own sun. Caleidoscope, however (that's what this one planet got called nowadays), does contain a large quantity of water. It consists almost entirely out of water, just like Jupiter's moon Europe. Yet Caleidoscope, is not covered in ice, it is a completely open water surface, like on Earth.
Something is alive down there, that's for sure. But no one believes it to be more than simple organisms like plankton or krill at most. Evidence of such organisms being present, is why the planet got called Caleidoscope in the first place.
The high radiation makes it difficult for large molecules to exist. The radiation breaks them back down to smaller chains. DNA even more so. Yet, something evolved enough to be able to thrive in these waters.
Living tissue, living beings back on Earth, protect themselves in different ways against our very own sun. Humans get a tan. Some creatures grow a thicker or tougher skin. Some grew even a shield. Literally. Since our sun's radiation is far milder than Caleidoscope's sun, it is witnessed less frequent on Earth. However, some weak skinned organisms such as seadslugs or mosses and such, use phosphorence to survive the deadly radiation.
Here on Caleidoscope, the waters just team with many different neon and phosphorescent colors. They swirl and sway on the currents otherwise invisible on the planet's surface, creating a real caleidoscopic view, hence the name. First it was just a nickname, but now, it has become the official name for this planet.
And now, finally, he had arrived here as well. Soon, he would be able to swim between all those magnificent, otherworldly colors, swirling all around him.
