Diagnosis Commonly known as the "pink" shrimp, it is slender and has a smooth body surface. The shell is somewhat thin, making it more difficult to transport in good condition than the other species. Moreover, although a deep red when alive, it becornes pink after boiling, a quality which also detracts from the commercial value of the unshelled product. The rostrum is about one and three fourths times as long as the carapace, slightly arched above the eyes, terminal half slightly ascending, armed with 12 to 16 teeth above (including 3 or 4 on the carapace), 6 to g teeth below, tip bifid. The anterior dorsal spine is situated at least as far forward as the distal third of the rostrum.
