Imaging technique: 

A laboratory cultured S. lessoniana being dissected to remove the giant axon for neurophysiological experiments. The technician is using a clothespin to close off the ink sac at this stage to prevent the release of the highly concentrated ink pigment. The mantle cavity has been opened ventrally to expose the viscera for removal and allow access to the axons.
