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.

November - A third consecutive La Nina has been confirmed, more rain, more floods. Strong prevailing
north winds make conditions difficult at Hastings Point.

September - Only a few finds on the beach, and still no diving. Spring is here so hopefully I can get back into the
water at Hastings Point as the river here is still not worth a dive. The forecast of another La Nina is not encouraging

Clavus exasperatus? - Hastings Point - Identified


May - Still no diving as rain periods since the floods have kept the water dirty. Continuing onshore winds that
normally provide interesting beach finds are producing nothing, so no new images. Not a great year so far. I have
added a couple of old finds that I had not previously included, and spent a lot of time on the net in an effort
to put ID's on some species, even attempting to name a few Crinoids. Thank you to Audrey Falconer, and the Marine
Research Group of Victoria, who have uploaded files on South East Australian species. These have been very helpful
as some of these species extend to this area. www.facebook.com/groups/294926707198638/files

As always, any corrections to my mistakes are appreciated.

April - After very heavy rain and record floods along the east coast, the Brunswick River is basically dead
and it will be quite some time before diving would be worth the effort, with a wetter than normal Autumn forecast.
The water quality on the coast is still poor so diving at Hastings Point is on hold, as that area also was subject
to massive rains. All I can show for the last couple of months are two newly named species of Murphydoris and
a few crustaceans that I had not previously uploaded. Any corrections to my attempted ID's would be welcomed.

January - La Nina is well underway and the river is a drain. Frequent rain, strong onshore winds and big
seas have made diving at Hastings Point difficult. Beach-combing not very productive either
