Mystery of the sea

I excited the station promptly after breakfast. I inspected the submersible as instructions dictate although I had been out merely hours before. On my last run I noticed something faint near the small rock formation where the angler fish usually roam. The object was far and I only saw when returning, but today I go there first. Small blinking lights light the way. Every few dozen meters a new light appears. At first down here I thought I was hallucinating. I wouldn't report or ask about the lights. One day while discussing floor vents and other areas to avoid exploring, as to not disturb the residents like tube worms, they mentioned a small population of angler fish living and concentrating near those rocks. The relief, I thought I was having some sort of underwater meltdown or something. Back up to, on the surface I mean, I do recall talk of giving myself time to adjust to life in the dark. To allow for life to come to you, appear before you, or simply try to swim away. However, I discovered the latter not to be much of a problem. After all, fish need their energy down here for more important things.
Few were the creatures that came to explore the lights in the midst of all the black. Beautiful really, the range of life that ranged from tiny to small or large to very large. There seemed to be no in between. Most life here was devoid of color, things that floated were usually attacked or had something attached to them. Then, I finally made it to my mystery. A large gelatinous creature that when the light hit it right glowed or rather shined in the peculiar way metal does, giving way to my imagination to believe there was more there than there really was.
On to the next mystery of the sea.
