In contrast to the long period of time required for morphological chromatic changes to take place, physiological chromatic changes are very fast events, taking from a few seconds to several hours (Noël, 1983). During the diurnal and nocturnal periods, pronounced differences in a shrimp’s color intensity and pattern result from the action of morphologically and physiologically different chromatophores (Chassard-Bouchaud & Couturier, 1968, 1969). The role of eyestalks, and consequently the glands present in these structures, is of major importance in the shrimp’s capacity to regulate chromatic changes, since the ablation of these structures induces the appearance of abnormal coloration (Chassard-Bouchaud, 1965).

7 Anecdotal observations note that large specimens in captivity may capture small fishes. 8 Anecdotal observations note that members of the wurdemanni species complex may attack soft corals in captivity. 9 These shrimps will nip the mantle of tridacnid clams, as well as damage corals, snails, feather duster worms and other invertebrates in the aquarium. 10 These shrimps will obviously be a threat to starfishes.

The so-called peppermint shrimps belong to a large number of distinct Lysmata species, although several of them may be closely related. Recently, Rhyne & Lin (2006) have identified a Western Atlantic wurdemanni species complex, reporting the existence of at least five different species: Lysmata ankeri Rhyne and Lin, 2006, Lysmata bahia Rhyne and Lin, 2006, Lysmata boggessi Rhyne and Lin, 2006, Lysmata rathbunae Chace, 1970, and Lysmata wurdemanni (Gibbes, 1850). Despite species-specific variations in their coloration patterns, all peppermint shrimp species generally exhibit semi-translucent bodies with longitudinal, transverse, and/or oblique red bands.
