Spider Songs
- Jumping spiders create substrate-borne vibrations with their abdomens and other body parts.
- These vibrations, perceived by the female through her legs, create a 'song' accompanying the dance.
Booty Shaking
- While most jumping spiders use their legs and palps in courtship, some species highlight their abdomens.
- The Habronattus decorus, for example, shakes its metallic pink abdomen.
Dance Genetics
- Spider dances are instinctive, not learned, and species-specific.
- Hybridization can occur, leading to unique dance combinations in offspring.
