29th October- Are Black Cod really Black?
Two dives at South Solitary Island today, started with Manta Arch on the first for the advanced divers. Another sighting of the big Queensland Groper was only brief as he raced away into the deep. We also saw a dozen Grey Nurse sharks that were spread out over the area. Finishing at Cleaner Station on that dive with some nice nudibranchs in the Cleaner cave gutter.
Dive 2 started at Cleaner Station with the divers cruising down to South Boulder. A number of Black Cod were spotted which sparked the question, “When they don’t look black, are they Black Cod?” Indeed Black Cod change their markings and colour as they swim from one environment to another. In a darker place like a deep gutter they will be black, near a rocky outcrop they become motley and striped, and then out in the water column they change to mostly grey.
Plenty of fish today and everyone enjoyed the conditions. Picture is a Huge Black Cod in the third gutter.
Visibility 12-15 mtrs
