  • ... that the jumping spider Portia fimbriata plays a deadly game of hide-and-seek with its favorite prey, Jacksonoides queenlandicus, another jumping spider
  • ... that sometimes the jumping spider Portia fimbriata can smell its favorite prey but not see it, and P. fimbriata jumps high in the air, so that the prey betrays itself by looking for the disturbance

For M: Philcha Proudly Presents Portia fimbriata - be very afraid if you're under 2 cm long

The species in Australia is represented by two distinct populations with differing behaviour - and even here more than one species may be involved. The northern Queensland variety is slightly smaller, has the most varied prey capture techniques of any animal in the world barring ourselves and other simians, prefers forested habitats, always uses a dead leaf as an egg receptacle, and is far easier to raise. The Northern Territory version is far less sophisticated in its hunting methods, prefers rocky overhangs and caves, never uses a leaf as an egg receptacle, and is quite troublesome in comparison to maintain, raise, and breed. Queensland Portia readily and carefully stalk and relish other species of Salticid spiders – Northern Territory Portia cannot work out how to catch them initially and treat them as they would web – building spiders before abandoning normal methods and just trying to chase them or jump on them whenever they come close – or else give up and ignore them.
