Glassy Sweeper

Pempheris schomburgkii

Sighting evidence at The Maze, Sint Maarten / Saint-Martin

The darker swim-through passages of The Maze are filled with shimmering balls of glassy sweepers, their copper-tinged transparent bodies forming dense clouds that part and reform around divers. By night they disperse to feed on plankton; by day they shelter in the darkest corners of the reef complex.
