AH_Jumping Spider Portia_3813.jpg
Jumping Spider (Portia sp.), specialising in hunting other spiders in their webs. In an example of aggressive mimicry, Portia sends vibrations through the victim's web to mimic trapped prey or a courting male. The web-owner reacts by running over to the source of the vibrations whereupon Portia launches the fatal attack, paralysing its victim with a carefully aimed bite. Portia is able to adapt is hunting strategy to different prey species. Danum Valley, Sabah, Borneo. June.
