Portia fimbriata: A jumping spider known for stalking other spiders and using varied prey-capture tactics. A close relative whose specialized hunting has been compared with Portia labiata’s flexible tactics.
Animal cognition: The study of how animals acquire, process, retain, and use information. Portia labiata provides a case for testing complex decision-making in an invertebrate.
Jumping spider: A spider in the family Salticidae, usually characterized by active hunting and acute vision. Portia labiata belongs to this family of visually oriented, active hunters.
Sit-and-wait predation: A hunting strategy in which a predator waits for prey to approach before attacking. Portia labiata often approaches prey actively rather than relying only on an ambush.
Aggressive mimicry: A predator’s use of signals that deceive prey and help bring it within reach. Portia labiata can imitate web vibrations that lure resident spiders toward attack.
Spatial learning: Learning the locations of places and routes through experience. Route-choice experiments examine whether Portia spiders use remembered spatial information.
Salticidae: The spider family that includes jumping spiders, with more than six thousand described species. This family supplies the anatomical and evolutionary context for Portia labiata.
Web-building spider: A spider that constructs a web used chiefly to intercept or capture prey. Portia labiata invades other spiders’ webs instead of depending on a prey-catching web of its own.
Web vibration: Mechanical waves traveling through a spider’s web, carrying information about prey, mates, and disturbance. The spider reads and produces vibrations while hunting web-dwelling prey.
Learning by observation: Acquiring information or behavior by watching another individual. Studies have tested whether Portia labiata can use observed events to guide prey capture.
