Lysmata wurdemanni is a species of saltwater shrimp in the family Lysmatidae, historically referred to as the peppermint shrimp in the marine aquarium trade. However, taxonomic revisions based on genetic and morphological data have revealed that many shrimp previously identified as L. wurdemanni actually belong to distinct species, including Lysmata boggessi, Lysmata rathbunae, and others native to the western Atlantic.

As a result, L. wurdemanni is now recognised as a more narrowly distributed species and is not the shrimp most commonly used in reef aquariums for Aiptasia control. That role is more accurately attributed to Lysmata boggessi, which has demonstrated reliable and consistent predation on Aiptasia and is widely regarded as the preferred species for natural pest control in reef systems.
