On 5th of February this year, “Scuba Steve” Simmons and Steve ‘Robbo’ Robinson dived at Edithburgh, South Australia. They both went for a scooter dive from the jetty, as they regularly do. They tend to go looking for crabs or other sea life, or just exploring. They just head off together in a random direction. On this occasion, they chose to... Read more

The Japanese Goby is similar to Krefft’s Goby

I have been helping Catherine McMahon from Port River Shellfish Restoration Project to monitor oysters being kept in baskets in the Port River system. One interesting aspect of the monitoring is the marine life that turns up in the oyster baskets. We have found fish, shells, pygmy squid, nudibranchs, flatworms, shrimps, blue-ringed octopus, etc.. I have been pleased to find... Read more

DREDGING AT OUTER HARBOR

Dredging will again be carried out in the Outer Harbor shipping channel and the swing basin next winter. The EPA has recommended that Flinders Ports use a smaller dredging vessel than what was used 13 years ago. In 2005, dredge spoil spread down Gulf St Vincent, reducing visibility and smothering seagrass. Environmental groups have called for all dredged silt to... Read more

Tropical Fish Cleaners and Their Mimics

I first heard about terms such as ‘symbiosis’ and ‘mimicry’ when I began researching for my “The Colour of Fish” articles in 1979. I probably also read about fish cleaners for the first time back then. I discussed symbiosis in my 1980 Journal article “The Colour of Fish”, saying “Symbiosis exists between clownfish and some sea anemones. The stinging tentacles... Read more
