Black triggerfish

Description:

Also called Black Durgon. It is a blimp-shaped triggerfish with bright white lines running along its dorsal and anal fins. From a distance, it appears to be completely black. However, upon closer inspection with good lighting, one can see that it is actually mottled dark-blue/green coloration often with orange toward the front of the head. Moreover, black durgons are capable of changing color based on their surroundings.

Habitat:

Wikipedia mentions Pacific locations but can also be located in the West Atlantic circumtropical areas as mentioned in http://www.iucnredlist.org/details/19360... This particular spotting has been made in Sharon's Serenity coral reef in Klein Bonaire. They are shy and do not let you approach them much. They swim back down to the deeper parts of the coral reef.
