Comparative analysis of the lower pharyngeal jaw in Mesoamerican cichlids of the Theraps-Paraneetroplus clade (Actinopterygii: Cichliformes: Cichlidae)

Key Points

• The analysis reveals distinct morphological traits of the lower pharyngeal jaw among cichlids.
• Key findings include significant variations in jaw structure that support dietary adaptations.
• Observational study across various cichlid species shows evolutionary trends within the theraps-paraneetroplus clade.
• Findings indicate potential evolutionary implications based on jaw morphology in food processing.
