Our Rapid Bay night dive was meant to be about little critters, especially nudibranchs smaller than half my little finder but when this Southern Calamari
(Sepioteuthis australis) came into my view I was suitably distracted.
In fact I was so distracted in the strong current that I had drifted 70m or more from the jetty pylons out into seagrass beds.
The amazing coloration of squids is due to the chromatophres in their skin giving them an almost electric vibrance at night,
After a handful of mid-water shots I eventually headed back to the jetty pushing directly into into the strong current for my navigation.
I saw a couple more squid during the dive but none posed for me the way this guy did.
