 Members of the genus "Portia" have hunting tactics as versatile and adaptable as a lion's.All members of "Portia" have instinctive tactics for their most common prey, but can improvise by trial and error against unfamiliar prey or in unfamiliar situations, and then remember the new approach.They can also make detours to find the best attack angle against dangerous prey, even when the best detour takes a "Portia" out of visual contact with the prey, and sometimes the planned route leads to abseiling down a silk thread and biting the prey from behind.
