The Oxycheilinus digramma, commonly referred to as the Cheek-lined wrasse and Bankcheek wrasse, is a marine species indigenous to the Indo-Pacific region, particularly the 🌊 Indian Ocean and the western 🌊 Pacific Ocean. This species holds a position of marginal commercial significance in local fisheries and has been integrated into the aquarium trade.
Mature specimens of Oxycheilinus digramma typically achieve a standard length of approximately 40 centimeters. The species is characterized by distinctive horizontal stripes along the sides of the head and prominent red spots on the anterior portion. The coloration of these fishes varies considerably, with shades ranging from pale gray to purple. Notably, individuals kept in controlled aquarium environments exhibit a reduction in stress-related behaviors when compared to those living in natural habitats.
The natural ecosystem of Oxycheilinus digramma comprises coral reefs, sheltered bays, and lagoonal environments, with their distribution extending to depths ranging from 3 to 60 meters. The early developmental stages of juveniles occur in symbiosis with the mushroom coral Heliofungia actiniformis, which provides a unique habitat for these young fishes.
The diet of Oxycheilinus digramma is omnivorous, encompassing a variety of marine invertebrates such as sea urchins, molluscs, and crustaceans. A notable foraging strategy employed by this species involves the utilization of larger fish as moving cover, enabling them to stealthily approach and capture prey.
