Inner Glow: Horror

We feared brain parasites in lake-water, but nothing really in sea water. We laughed at the tourists who wouldn't go in the water for fear of shark attacks, which were so rare as to be less risky than driving to the beach. We didn't think much of the jellyfish that washed up on the beach, simply tried to avoid stepping on them. When the glowing jellyfish began to gather in the shallows, we all went out with cameras. It was reported on the news and everything. I stepped on one as we left and felt a single sharp jab. I thought nothing of it until my foot began to glow in one spot.


Inspiration: This is what happens when you google "Ellen Datlow likes" (because of Fearful Symmetries anthology) and look at the pictures.
Story potential: Medium
Notes: Parasitic jellyfish living inside the human as they get larger. When they're mature enough, she will cough/vomit them up into the saltwater tank (eventually, after just killing the first few), and is a struggling model whose career takes off when this starts. Conflicty! Should maybe be male instead of female, to make story more transgressive? Possibly gay, to add difficulty adopting? Also note, the tone of this is all wrong for the story.
