, live in pairs, and are brightly colored, often in contrasting reds and yellows with white antennae. Other species are the "peppermint shrimp", which have semi-translucent, red-banded bodies, and live in large groups. Some peppermint shrimp perform cleaning behaviors, but less actively than do the cleaner shrimp. The genus has been studied with interest due to its unusual sexual system, protandric simultaneous hermaphroditism. While some other taxa of shrimp undergo sequential hermaphroditism, they have only been observed changing from male to female. In ''Lysmata'', males become true hermaphrodites instead of females. So far, every species studied has been confirmed to have this sexual system. During their "female phase" they actually have functioning male and female tissues in their gonads and produce both types of
