متن کاملHabitat Segregation among Trophic Morphs of the Cuatro Ciénegas Cichlid (Herichthys minckleyi) Segregación de hábitat entre formas tróficas de la mojarra de Cuatro Ciénegas (Herichthys minckleyi)
Herichthys minckleyi is an endangered, trophically polymorphic cichlid endemic to the Cuatro Ciénegas basin of Coahuila, Mexico. A molariform morph has stout pharyngeal teeth whereas a papilliform morph has numerous fine pharyngeal teeth. Individuals with intermediate pharyngeal dentition also exist, as does yet another morph, called piscivore. Previous studies indicated that morphs utilize dif...
متن کاملTrophic morphology, feeding performance and prey use in the polymorphic fish Herichthys minckleyi
Question: How does pharyngeal jaw morphology influence feeding performance and prey use in the trophically polymorphic cichlid fish Herichthys minckleyi ? Organism: Herichthys minckleyi exhibits two discrete pharyngeal jaw morphologies. Molariforms possess flattened teeth and enlarged pharyngeal muscles, whereas papilliforms exhibit more gracile jaws, pointed teeth and smaller muscles. Data: We...
