Giant Cuttlefish returns to the Spencer Gulf for Coitis

South Australian scientists are ecstatic to find that the Great Australian Cuttlefish has returned to the Spencer Gulf for breeding this year. Their numbers have been down over the last few years and scientists don’t know why, or where they went.

The cuttlefish, with it’s blue blood pumped through three hearts, and the ability to change colour at the drop of a shell, makes the cuttlefish an enigmatic creature to say the least.

The increase in the breeding aggregation numbers this year is also a source of interest to scientists.

“We’ve looked at a whole range of biotic and abotic factors that could have contributed to it, but nothing jumps out.” says Professor Bronwyn Gillanders.

Gillanders says she is quite excited to that there were a lot sighted early in the season, but that the proof will be when surveys are completed to estimate the abundances on this years breeding aggregation.

Spencer Gulf Ecosystem & Development Initiative Workshops

Workshops to discuss the progress on the Spencer Gulf Ecosystem and Development Initiative (SGEDI) are being conducted in regional areas and Adelaide over the next four weeks.

This is a four year program, led by the Environment Institute at the University of Adelaide. The program aims to provide all stakeholders with access to independent and credible information. We seek to enable positive environmental decision making for groups and individuals associated with the Gulf.

Cumulative Impact and the Spencer Gulf System

• an assessment of key knowledge gaps
• pathways for the next period of research
