Kingdom: Animalia (Animals)
Indigo hamlets range from seven to 14 centimeters in length. Their bodies contain a number of broad indigo/blue bars separated by thinner white bars.
This species is found in the tropical Western Atlantic in Haiti, the Bahamas, Jamaica, Cayman Islands, Florida (USA), and continental western Caribbean Sea . They are absent in Puerto Rico, the British Virgin Islands, the United States Virgin Islands, and the Lesser Antilles.
Indigo hamlets live on coral reefs at depths ranging from three to 45 meters.
Indigo hamlets are solitary and spend the majority of their time hunting alone in defended home ranges.
Reproduction in indigo hamlets takes place year round. They are simultaneous hermaphrodites, which means that they can be reproduce as males and females at the same time. Before sunset, the fish leave their home ranges to search for mates. After finding a potential mate, one of the hamlets acts as a female while the other acts as a male. They release gametes into the water column during a three second “mating clasp”. After approximately 15 minutes, the fish repeat the process but with each individual switching sex roles. Eggs are fertilized in the water column. After the eggs hatch, the larvae enter the pelagic stage until they settle back on the reef.
The indigo hamlet is not deemed to be a species at risk.
