Markerless tracking suggests a tactile sensing role for forelegs ofDolomedesspiders during locomotion [article]

Kiri F. Pullar, Michael G. Paulin
2018 bioRxiv   pre-print
Here we describe a markerless motion capture technique and its application to gait analysis in the New Zealand semi-aquatic hunting spider,Dolomedes aquaticus.  ...  Our results indicate how specialization of limb function may contribute to locomotor efficiency and agility of a specialized hunting spider, and how arthropod design principles may contribute to developing  ...  Our data will now be compared with results obtained previously for spiders 430 and other arthropods; this will be followed by an evaluation of the tracking algorithm. 431 Kinematic variables and speed  ...
