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.

April - After a Tropical Cyclone and two intense east coast lows, the beaches and rivers here are recovering
from being battered by heavy swell and continual rain. Hastings Point also suffered heavily but should be worth a
dive after the current school holidays. I have revised my Ascidacea page, adding some new species not previously
included and naming others. Any help with identification, and corrections, is appreciated.

February - Not much new to report. A recent run of on-shore winds left a lot of cuttlebones on the beach
and, although a common occurrence here, some were in very good condition. My thanks to Dr Amanda Reid at
the Australian Museum for her help with identification.

January - After a lot of rain, the river is still not worth a dive, and the Christmas school holiday crowd
prevents parking at other spots. Just a few more weeks and they will all go away!!

September - Flat seas and low tides have enabled me to look closely at the masses of Galeolaria worm tubes on
the north seawall, and the many species that live in and around them. The tiny parasitic snail Pseudoskenella depressa
is a very interesting example.

March - After 3 La Ninas the current El Nino has been the wettest I have seen here.
Unfortunately the river is badly affected and is still not worth a dive. I have also
not been able to dive at Hastings Point since before the Christmas holidays. Nothing
on the beaches as well.

November - not a lot of opportunity to get in the water lately. A search of the
mangroves revealed large numbers of the seaslug Elysia bangtawaensis in
mudcrab holes and shallow natural drains.
