According to Crosscut Blog a brand new species of spider has been identified on Seattle's Foster Island by a scientist and arachnid expert at the Burke Museum on UW Campus.
(This is the string of islands next to the 520 Bridge and is actually part of the WA Park Arboretum).
This discovery is significant of course, not only as an incredible scientific discovery but because of the upcoming expansion of the 520 Bridge. The extensive environmental process which is needed to undertake this expansion includes cataloguing the wildlife on Foster island and the Arboretum, which of course includes wetlands and salmonid habitat.
"..........it was a female crab spider of the genus Philodromus, and one of the "Philodromus imbecillus" group (about 10 closely related species, of which only one, Philodromus insperatus, is known from Washington)."
