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.

The establishment of redback spiders in Ennore could have implications for local ecosystems and human health.
