Help discover a new species of 'Ctenotus' skink at Mt Coot-tha
In the Eighties,actually discovered the first known specimen
at the time in the Brisbane area.
IT all started when i was expelled from Kindergarten over 40
years ago for droping my bug box,and all the insects(i was into cicadas at the time,escaped and all the kiddies had to be evacuated).so yes,have been collecting for a long time.
My stories would make Gerald Durell look like picnic.
nothing cute about those things at all ewwwww
