Rafting Crab
Guardian: Noah Vella
Plagusia squamosa
This crab will attach to whatever is passing by, a fallen tree, a bit of debris, a snorkeler's leg. They are sometimes found on the backs of turtles where they scavenge for parasites and then catch scraps of food that break away as the turtle eats the algae at the bottom.
..and then they move on, a drifter, a hobo, a hitchhiker.
