Dissection of a Blue Mackerel
Scomber australasicus

This site shows the dissection of a Blue Mackerel (view fact sheet). The dissection was performed by Year 12 students at St Vincent's College, Potts Point, Sydney in May 1998, and photographed by staff of the Australian Museum Photographic Department.

The aim of the dissection was for students to become familiar with the internal organs of a fish, primarily the swim bladder. This site has been put together to assist students and teachers with similar dissections. Many of the organs that are encountered during a typical fish dissection are named and discussed.
