Chris,
Concerning your message #14839:
We have collected a number of the P. hedgpethi for the WA Museum. The people at the museum, with the help of a P. hedgpethi specialist, are going to try and match the DNA and establish the origin of the population that appeared on the Rockingham Wreck Trail.
Kindest Regards,
Mick Tait

Dear Mick,
I know we live in an age of specialisation - but a P. hedgpethi specialist? Do the tax payers know?

Joking aside, it would be interesting to look at the origins of a number of these hitch-hiking animals. Another candidate I have mentioned often isThecacera pennigera  which is nominally considered a 'Nth Atlantic' species because it was described from there first. But it is found quite widely in the west Pacific where it is quite variable in colour pattern, while in the Atlantic it has only one colour form. From my understanding of genetics, that would suggest the Pacific is a more likely origin than the Atlantic. Please let us know if the specialists discover the origin of the P. hedgpethi population.
Best wishes,
Bill Rudman
