User's notes

Seen on handrail in Rainforest Gully. Not sure what is happening here, First spider seems to be holding or eating a smaller version of itself. ??? The last two pictures are of a nearby spider but also looked like the same species, perhaps a younger spider?

Or has it just shed its skin?

It is certainly eating another spider, whose elongate abdomen suggests Helpis minitabunda, rather than its own species.
