  1. 💁🏻‍♀️ TIL: 🕷️💨 The jungle #huntsman #spider from #Queensland reached 3.59 meters per second, doubling the previous #arachnid speed record.

    Researchers at #Imperial College #London measured 162 #species across four #continents to study spider #locomotion. They found that longer legs relative to body size predict greater speed.

  2. 💁🏻‍♀️ TIL: 🕷️🕸️ Researchers from #Macquarie University discovered a new ballista #spider species in #Queensland’s #CapeYork #rainforest that builds a spring-loaded web snare targeting green tree #ants.

    When an ant bites the cone, tension lines fire it into the web at 1,367 m/s² – roughly 140 G – making this the most power-dense biological catapult known. The spider’s use of pheromone-mimicking silk represents a #hunting strategy not seen before in any #arachnid.
