resource preview

This 12 minute video segment from Catalyst outlines the fascinating and unique features of the giant cuttlefish and its mass breeding at Point Lowly. Then it explains how scientists have determined the vulnerability of this species- the fact that the eggs are sensitive to high levels of salinity and the fact that they die after breeding, so that destruction of the eggs in one year could have a dramatic impact on the whole population. Finally there is the debate as to whether the establishment of a desalination plant for the use of the mining industry in their habitat will prove to be a mortal threat.
