Dolomedes sp. scuttled out very quickly from underneath dock attempting to attack live bait fish (probably golden shiner Notemigonus crysoleucas) after a mis-cast resulted in bait fish landing just off edge of dock near Sebago Lake, Maine.

Study: Fish-eating spiders found all over the world

A lot of people are afraid of spiders, our creepy, crawly, eight-legged friends.

The findings are included in a new report out this week in the journal Plos One, co-authorers by arachnologist Martin Nyffeler at the University of Basel in Switzerland. Nyffeler joins the show with more.
