Cheers Neo, thats interesting.
Also cheers Klue cos I knew they could swim but didnt think such a big snake could climb.
See you learn something everyday.
On the subject of nasties, I pulled quite a large paralysis tick out of my border collie this morning.
He wasnt showing any signs, I just happenned on it while giving him a hug.
Bloody thing was almost a cm long and was well fed.
I dont think we have them in our area normally so i suspect it arrived via my brothers dog after his trip to the South Coast where I know they are prevalent.

We lived in a high set house with the laundry downstairs, one morning mum was doing the washing around 5:30am in the morning and it took her 15mins to realize there was a 1.6m carpet python draped across the washing machine.
Anyway she got all us kids to come down and see it and we watched it climb up and disappear into the ceiling under the bathroom. So we assumed it would be warmed up each night when we would all make our way through the shower/bath.
It stuck around for about a year and we saw it quite a few times, never had troubles with our cats or dog and also cleaned up all the rats and mice we had. Then one day we found it crossing our back lawn and climb up tree never to be seen again.
Adult female engorges for a period of 6-30 days, the time being dependent on weather- slower when cold. The 30 day engorgement time is derived from laboratory culture colonies. Under natural conditions, the time taken for an adult female to engorge while on the host varies from 6 to 21 days, the period being longest in cool weather. When fully engorged (replete), the adult female drops off the host to the ground

Once a suitable host is found, the larvae will blood feed for 4-6 days, drop from the host and moult to the eight-legged nymphal stage. Nymphs require a further blood meal for 4-8 days before moulting to the adult stage. Both female and male ticks quest for a host, but for different reasons; the female for a bloodmeal, the males to search the host for female ticks in order to mate and sometimes feed from them. Males may actually parasitise the female ticks by piercing their cuticle with their mouthparts to feed on her haemolymph (the tick's blood) and up to 3-4 males have been found feeding on one female tick. Male ticks rarely bloodfeed on a host. The adult female Paralysis tick will feed for up to around 10 days, drop off the host and lay eggs over several weeks. The entire life cycle of the Paralysis tick, involving 4 stages and 3 hosts, will take around a year to complete. Each life stage can be present throughout the year, although for the Paralysis tick, adults are more abundant in the spring and the early summer months, larvae in mid to late-summer, and nymphs during winter.

An adult tick has one job -- to reproduce. In hard ticks, the female tick attaches to a host and feeds, often for more than 24 hours, before mating.
6. Do animals develop immunity to the tick paralysis toxin?
Native animals which are the natural hosts of Ixodes holocyclus appear, (when in their natural environment), to develop an immunity to the harmful effects of the tick toxin, and can carry large numbers of ticks without ill effect.
Dogs and cats which live in areas where they regularly pick up ticks will also tend to develop their own immunity. This depends on them getting small doses of tick toxin initially, not enough to cause severe illness, but enough to start the production of antibodies by the animal's immune system. As they pick up more ticks and are injected by gradually increasing doses of toxin this immunity can become quite strong.
Unfortunately this immunity is not long lasting and can be lost from one season to the next if there are no ticks on the animal in the time between. A previously immune dog can therefore suddenly become affected by tick paralysis. Owners should be aware of this risk.
Haemaphysalis (Bush Ticks) which resemble Ixodes to some degree but do not inject a toxin.
so dirty!!
