Unusual pigmentation and morphological variations in four flatfish species (Order: Pleuronectiformes) from Indian waters
Year: 2025
Type: article
Abstract: This study reports the first record of unusual pigmentation and morphological anomalies in four flatfish species, Cynoglossus arel,C. lingua,Dagetichthys commersonnii, andPseudorhombus triocellatus, collected from Indian waters. Unusual pigmentation included ambicolouration inC. arel and D. commersonnii. Morphological anomalies such as fin cuts, caudal deformities, accessory fins, and vertebral fusion were observed inC. arel,C. lingua, andP. triocellatus. These anomalies may indicate developmental stress or environmental disturbance, potentially affecting individual fitness and survival because functional morphology influences ecological performance. Comprehensive, multidisciplinary research is essential to identify specific causes, assess ecological consequences, and prepare conservation strategies.
