I would like to talk about the fact that only a tiny percentage of the ocean has been discovered and studies as i fond that to be very fascinating. Indeed, millions of people express interest in visiting space and going to the moon but very few seem passionate about discovering what is in the ocean. When the first man landed on the moon in the 1970s it was a great advance in technology but up to then, only a small amount of research was done on the vast underwater part of our planet. The ocean is enormous and there are so many alien like creatures in it that I feel like it could be studied for what could feel like an eternity. I'm very interested by the abyss and that interest sparked from an episode of "Blue Planet" by Alex Dupont that I watched when I was younger. I really find it crazy that the ocean can be up to around 10km deep at it's deepest parts and that new marine species are discovered nearly every day. One of the most interesting aspects of underwater creatures is that as you go down deeper, there is less light ; therefore, after a certain depth, many creatures produce their own light, which I find to be entrancing. Indeed, some animals can produce all sorts of coloured light. On the opposite side of the scale, because there is no light in the abyss, some animals have evolved to be entirely transparent as to stay invisible and creep up on their pray or on the other hand to stay hidden from their predators. Angler fish are very intriguing to me because they stay deadly silent in the depths of the ocean and do not move. However, in order to entice other fish, it dangles a very bright light above it's forehead, leaving its mouth wide open. Then, when a fish gets close enough to the angler fish's mouth, it viciously snaps it shut. Anyway, I have kind of deviated from the original subject but this is my opinion on the fact that only a small amount of our planet has been researched and discovered.
