Use this extra large plain preserved perch specimen for a hands-on exploration of the external and internal anatomy of a fish. Its large 9"-12" size & easily located organs make it an excellent dissection specimen.
Species is typically Pomadayses magranthus. Occasionally we substitute yellow perch, Perca flavescens, based on supply availability.
Before beginning your dissection, observe the external anatomy of the perch, including the lateral line along the side of the fish, the perch's mouth, eyes, external nares, teeth, gill covering (also known as the operculum), spiny dorsal fin, soft dorsal fin, caudal fin (tail), anal fin, pectoral fin, pelvic fin, and more.
Use scissors (designed for dissection), a scalpel, and maybe even a hand lens to identify and study the internal structures inside the body cavity, such as the swim bladder, gill structure (including the soft gill filaments, gill arches & gill rakers), stomach, urinary bladder, gonads, pancreas, liver, and other internal organs and parts of the circulatory system, digestive system, reproductive system, and more.

10+ pricing is based on bulk-packed specimens. When necessary, you will receive a combination of 10-packs and individually packed specimens to fill your order.
Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.
