Opossum Shrimp is a generic term applied to a group of small shrimps which are difficult to identify precisely from photographs. As a group they are common all around the UK and are also called Mysid Shrimps. They are up to 2cms long and are frequently seen in large groups hovering just above the bottom. They feed by creating a current with the appendages around the “chest” area and collecting particles of suspended matter. Females can be seen carrying eggs in a brood pouch which are quite visible due to the transparency of the underparts.
