Giant Cuttlefish Attack SCUBA diver 

Giant Cuttlefish (Sepia apama) attack on female dive buddy. Cuttlefish breed and lay their eggs around this time of year - and become very aggressive and "frisky". They are very intelligent and are attracted to "shiny" things such as this torch, and especially anything that is yellow in colour.
I motioned to her to switch the torch off, unfortunately she didn't understand and this footage is the result. This is the first time this diver had ever seen a cuttlefish. This cuttlefish followed us for another 20 minutes.
