How to play Anatomy of a cod

Anatomy of a cod is an interactive simulation.

During this interactive experience, you will dissect two cod fish (one spawning, one not spawning) and record your findings in the data sheet.

The experience is broken down into four main sections which can be completed in any order. They are:

  • Rotate the cod in 3D

  • Measure the cod

  • Weigh the cod

  • Explore the inside of the cod

Before you begin:

You can use an internet browser on a computer or tablet to dissect the cod and record your findings.

You will dissect two cod caught in different reproductive phases (spawning and not-spawning). 

Each section requires you to complete a task and record the information on the Data Sheet.

Dissecting the cod

Drag the scalpel counter-clockwise along the dotted line to reveal the inside of the cod.  

Exploring the cod's anatomy

The black dots are clickable hotpoints. 

Click on a hotpoint to read a description of that part of the cod's anatomy. 

The clipboard icon was selected by the user to open Specimen A’s Data Sheet on the right side of the screen. The Data Sheet has fields for the user to note the cod’s length, weight, egg visibility, and liver weight. A “Next Specimen” button appears at the bottom of the sheet. The clipboard icon, liver weight field, egg visibility drop down menu, and “Next specimen” button are highlighted. The dissected cod is shown in the background on the left side of the screen.

Recording your data

Click the Data Sheet icon to the right of the cod to open the Data Sheet.

Record the visibility of the cod's eggs and the cod's liver weight.

Click Next Specimen to collect new data.
