Certain species of fish and several types of cleaner shrimp may assist the fish in large numbers and even go inside the mouth (and then to the gill cavity) without being eaten.

REPRODUCTION: L. amboinensis initially develop and reproduce as males then develop female reproductive organs to become hermaphrodites and function as both males and females throughout the reproductive cycle. This system called protandric simultaneous hermaphroditism is so far known only from caridean shrimp in the closely related genera Lysmata and Exhippolysmata.

REMARKS: Cleaner shrimp advertise their services by their bright coloration and by waving their very long antennae, which contrast with the dark recess of their station.

Jacques, a character in Finding Nemo, is a humpback cleaner shrimp. In aquaria, cleaner shrimp are valued because they clean not only the fish, but the tank as well.
