SEA SLUGS

AND  OTHER  MARINE  INVERTEBRATES  OF  THE  TWEED - BYRON  COAST,  AUSTRALIA.

UPDATES

Latest additions. New species on site and better images of species already listed.

HELP NEEDED! Any feedback on species not named, and corrections to my mistakes, would be greatly appreciated.

The locations given are where I have found these species but this does not imply that these are the only places
on the coast that they can be found.

June - I still have not been able to get much diving done this year, too many other things getting in the way.
Hopefully that will change very soon. After revising my Ascidiacea shots I have been able to add some new species
along with newer images. Any help with identification would be greatly appreciated.

November - The Brunswick River is still hardly worth a dive, very little to see and over the last 2-3 years the
decline in the biodiversity is very evident. Many of the species that were fairly common several years ago are
no longer seen and although the river looks fine, a closer inspection shows a lot of sand and detritus build-up.
The river also suffers badly from run-off after rain, a lot more than it did a decade ago. Sad to see this happening
which is why I have concentrated more on Hastings Point and Seagull Rocks the last couple of years. I will also be
glad to see the end of 2020, not a great year.

September - Despite the difficulties of this rotten virus I have made some nice finds over the last few months.
Several Thecacera pacifica were found in the river before the rain, also Conus litteratus and Euprotomus aratrum,
both long dead but well at the southern limit of their range. Some weed-washing at Seagull Rocks produced micro
shells and amphipods.

June - Following huge rain before Christmas the first half of this year has been dismal. Isolation is finally
beginning to relax so hopefully things will begin to improve.
