The brown huntsman spider (Heteropoda jugulans) has been recorded as the fastest spider in the world, reaching speeds of up to 3.59 metres per second (8 mph). This finding emerged from a comprehensive study conducted by scientists from the UK and Germany, analyzing over 250 spider species to determine their running capabilities.
Speed Record Set by the Brown Huntsman
During the research, the brown huntsman outpaced the previous record-holder, the Moroccan flic-flac spider, which only managed a speed of 1.7 m/s. The study involved collecting 162 spider species, primarily from London and Greifswald, along with samples from North America and southern Europe.
Dr. Christofer Clemente, an evolutionary biomechanist from the University of the Sunshine Coast, highlighted the unique locomotion methods of spiders, stating, “Spiders don’t move using just muscle – they use a combination of muscles to retract their limbs and hydraulic pressure to push them outwards.” This distinct mechanism contributes to their impressive speed.
Unique Characteristics of the Brown Huntsman
The brown huntsman is commonly found along Australia’s east coast, particularly in south-east Queensland. These spiders can grow to the size of a human hand and are known for their hairy legs. Although they are venomous, bites to humans are rare and typically result in mild effects.
While the peak speed of 3.59 m/s was recorded only briefly, the average sustained speed of the brown huntsman is closer to 2 m/s. Dr. Clemente noted that this is still remarkably fast. He speculated that the brown huntsman may represent an optimal body type for speed among spiders.
Implications of Spider Speed Studies
Dr. Jonas Wolff from the University of Greifswald, who co-authored the study, emphasized that this research is the most extensive comparative analysis of spider speed to date. Understanding spider speed can provide insights into their ecological roles, including how they interact with their environment and disperse.
Interestingly, the findings revealed that it is not necessarily the largest spider species that run the fastest. The study indicated a threshold in body mass beyond which running speed declines due to mechanical constraints.
- Fastest Recorded Speed: 3.59 m/s (brown huntsman)
- Previous Record: 1.7 m/s (Moroccan flic-flac spider)
- Spider Species Analyzed: Over 250
- Average Speed: Approximately 2 m/s (brown huntsman)
In conclusion, while the brown huntsman is currently considered the fastest spider, Dr. Wolff cautioned that there may be untested huntsman species that could surpass this record.
