Morphology Of The Inner And Peripheral Ear Of The Loricariid Catfish Pterygoplichthys Gibbiceps K., Brian David Rodgers
Mahurin Honors College Capstone Experience/Thesis Projects
The morphology of the peripheral and inner ear structures was studied in the loricariid catfish Pterygoplichthys gibbiceps. Specimens (n=6) were preserved in fixative (4% paraformaldehyde, 2% glutaraldehyde in 0.1M phosphate buffer) and dissected for examination of the gross morphology (using light microscopy) and ultrastructure of the auditory sensory epithelia (using scanning electron microscopy). One additional specimen was cleaned in a dermestid beetle colony in order to examine the osteology of the skull. The swim bladder of P. gibbiceps is divided along the midline of the fish into two reduced but equal lobes residing in two laterally oriented bony encapsulations. Immediately …
