Original
Reason
I was initially shooting this spider simply as an illustration of a fishing spider - the example of autotomy coming as a unexpected bonus. I wasn't sure if this was an example of autotomy or of a less voluntary "ripping off" amputation, but I had this confirmed by Martyn Robinson a naturalist at the Australian Museum. The picture is of high technically quality (sharp, nice lighting, nice composition showing the spider's ability to walk on water) and is of an interesting subject.
Caption
A fishing spider in the family Pisauridae and genus Dolomedes which has jettisoned two of its legs - most likely as a response to being attacked by a predator

Actually, perhaps you should disregard this. I'm not sure what's going on with this article, but you can see that it says (C)1926 even though the publishing date is 2005. In web of science this article is cited to 1926. The author published most of her other work in the 20s and 30s and according to the site of some B&B in her old house, she is now (predictably) dead. Other recent articles say this is in fact a real phenomenon, e.g. Brueseke MA, Rypstra AL, Walker SE, et al. Leg autotomy in the wolf spider Pardosa milvina: A common phenomenon with few apparent costs . AMERICAN MIDLAND NATURALIST 146 (1): 153-160 JUL 2001; Guffey C. Costs associated with leg autotomy in the harvestmen Leiobunum nigripes and Leiobunum vittatum (Arachnida : Opiliones), CANADIAN JOURNAL OF ZOOLOGY-REVUE CANADIENNE DE ZOOLOGIE 77 (5): 824-830 MAY 1999; Guffey C. Leg autotomy and its potential fitness costs for two species of harvestmen (Arachnida, Opiliones) . JOURNAL OF ARACHNOLOGY 26 (3): 296-302 1998. Mangostar (talk) 15:44, 16 December 2007 (UTC)[reply]

Long story short: it looked like there was a 2005 article saying this phenomenon didn't occur in spiders. But somehow that article is actually from 1926, not 2005, and autotomy has been documented in at least several other species of spiders in recent journal articles.
