To add to its mystery P. otwayensis weaves highly stereotyped ladder - shaped webs, where they stand facing down after sunset, waiting for preys which will be caught
by using the ladder as a trap — a behavior which was already described in detail
by now retired
arachnologist Mike Gray (Australian Museum) for the only known other species of this genus, P. carraensis.
Saraceno further expanded on this work, in collaboration with world leading
arachnologists and researchers from MIT, among others,
by being the first to scan, analyse, and reconstruct a three - dimensional spider web subsequently presented at Bonniers Konsthall, Sweden in the following year.
