Also known as swarthy-headed goatfish and half-and-half goatfish, the bicolor goatfish (Parupeneus barberinoides) belonging to the family of Mullidae comprises a total of six genera along with 86 identified species. The fish has derived its name from its appearance due to its goatee or pair of barbels on the chin and the dual body color.

The anterior is burgundy while the posterior is white-yellow. Moreover, goatfishes are also known to be expert mimics and capable of camouflaging themselves by changing colors.

This is one of the reasons why they maintain close contact with the oceanic sand bed.

Whenever the fish senses a predator looming in the vicinity, it mingles with the sand, acquiring a pale shade to remain unnoticed. For instance, the mimic goatfish can resemble the blue-striped snapper by mimicking its color patterns.

However, the species has been marked as vulnerable which means that their population needs to be preserved. Uncontrolled fishing and harvesting are great threats to this species. Moreover, the marine aquarium trade has resulted in overexploitation. Conservation measures must be implemented at the earliest with stringency to protect this species from the brink of extinction.
