Researchers have identified the presence of redback spiders (Latrodectus hasselti) in Ennore Creek, Tamil Nadu, marking the first record of this species in a coastal lowland habitat in the state. The spiders were found in an old fly-ash dump pond, indicating potential adaptation to disturbed environments.
- 01The redback spider, also known as the Australian black widow, was first identified in Tamil Nadu in Coimbatore, with previous sightings in Madurai and Kiluvamalai.
- 02The recent discovery in Ennore Creek is significant as it represents a shift from hilly regions to a coastal lowland habitat.
- 03The warm and disturbed conditions of the decommissioned fly-ash pond may favor the establishment of the redback spider population.
- 04Adult female redback spiders possess potent venom that can cause severe symptoms in humans, although fatalities are rare due to the availability of antivenom.
- 05Researchers emphasize the need for further surveys to assess whether this finding indicates a broader range expansion of the species along the coast.

In a recent study, researchers have documented the presence of redback spiders (Latrodectus hasselti) in Ennore Creek, Tamil Nadu, marking the first record of this venomous species in a coastal lowland habitat in the state. Previously, the species was only found in hilly regions such as Coimbatore and Madurai. The spiders were discovered in an old fly-ash dump pond, surrounded by salt marsh and grassland, suggesting that the disturbed conditions may be conducive to their establishment. The study, a collaboration between the French Institute of Pondicherry and the University of Madras, highlights the potential adaptability of the redback spider to coastal estuarine environments. Notably, the venom of female redback spiders can cause serious medical issues, including intense pain and muscle spasms, although fatalities are uncommon due to the availability of antivenom. The authors of the study call for additional field surveys to determine if this sighting is an isolated incident or part of a larger trend of coastal range expansion.
