Black slug (Arion ater)
These things should NOT be in Australia but were first reported in 2001 in the Dandenong Ranges 40km east of Melbourne. They were next seen in 2005 and now in 2012 I found dozens. There have also been reports of them in the Otway Ranges to the south-west of Melbourne. Regarded as a pest in Europe and England (their origin) they seem to have survived the worst drought in Victoria's recorded history and therefore might be regarded as 'established' here.
I have just found out they are appearing in Tasmania too. What are sapiens doing.!!
