Totoka River krebs cycle

geddit? like crabs? this is a weak start but whatever @Coelacanth 

Not many days ago, this river had brought Starbuck great joy in her new friend Deirdre. It had also revealed to her the mystery of crabs. Now that she was back from her brief journey into the depths of the wild, she wanted to revisit the river delta and its strange fauna. The coywolf nosed through the dense bunches of sea grass until she came upon another crab, its red shell a beacon in the colorless sand. Starbuck dropped low, following from a distance and observing it as it scuttled over the thin layer of water skimming over the sand.
