Professor Kris Helgen of the Australian Museum praised the research for highlighting the importance of museum collections in modern scientific studies.

Male funnel-web spiders are significantly more venomous than females, with the male 'big boy' particularly capable of delivering large amounts of venom.

Funnel-web spiders are primarily found in eastern Australia, particularly within a 100-mile radius of Sydney, and are most active from November to April.

The antivenom for funnel-web bites, developed in the 1980s, remains effective for all newly identified species, according to Dr. Helen Smith.

The discovery of these species has significant implications for venom research and the development of antivenoms, as it accounts for biological differentiation.

A recent study published in 'BMC Ecology and Evolution' has identified the Sydney funnel-web spider as three distinct species, including a newly discovered species named Atrax christenseni, also known as 'the big boy.'

To protect the newly identified Newcastle funnel-web species, precise locations remain undisclosed to prevent over-collection.

This study follows the recent discovery of the largest funnel-web spider ever recorded, a male Atrax robustus measuring 9.2 cm.

The Australian Reptile Park has seen unusually large funnel-webs, including notable specimens like 'Hemsworth,' named after Australian actor Chris Hemsworth.

Danilo Harms, a co-author of the study, emphasized that understanding species-specific differences can enhance future antivenom development.

Professor Geoff Isbister noted that while funnel-web spider bites are rare, they can be severe, underscoring the importance of seeking immediate medical help if bitten.

Atrax christenseni can grow up to 9 centimeters in length, nearly double the size of the common Sydney funnel-web, which typically reaches 5 centimeters.
