 | | Mysis relicta, commonly called Opossum shrimp, is a key food source in the Great Lakes for forage fish like sculpin, rainbow smelt, and alewife. |
 | | Like all arthropods, Mysis shrimp feature a segmented, shell-like exoskeleton that is shed several times to allow growth. |
 | | Its head is fused to the first thoracic segment, and several pairs of laterally moving appendages, called maxillae and maxillipeds, extend forward beyond the head. |
