Neither are they parthenogenetic as far as I can tell!!

I'm in favour of getting rid of blow-ins like this one, and not waiting
for CG #2 to show up and start a family.  Botanical weeds are still
streaming on to our shores, but I think large zoological weeds like this
one should be shot on sight to make the point about the danger to local
ecosystems of large, prolific, exotic organisms.

Any reported missing yet?  This might not even be a blow-in; but proving
otherwise might be tricky unless those who keep them can guarantee there
are none missing.
