Biodiversity Snapshots: 75 Species Documented Across Puducherry’s Rich Ecosystems

In a focused biodiversity monitoring effort this June, a remarkable 75 species were documented across a wide range of ecosystems in the Puducherry bioregion. The data was gathered through a combination of field-based observationsand citizen science contributions via iNaturalist, reflecting the region’s ecological vibrancy and the growing awareness around conservation.

Covering marine, estuarine, freshwater, terrestrial, and urban landscapes, the documentation highlighted the vast spectrum of life that thrives in and around Puducherry.

Among the marine species, key sightings included Sillago Whitings, the eye-catching Bridled Triggerfish, and Cupped Oysters, revealing the productivity and biological richness of coastal waters.

In the estuarine and freshwater systems, diverse aquatic life was observed — from Threadfin Silverbiddies and Common Ponyfish to the beautifully coloured Stream Ruby damselfly, each an indicator of healthy transitional ecosystems.

Terrestrial habitats yielded several significant avian and reptilian records, such as the Pied Bushchat, Grey Junglefowl, and the soaring Brahminy Kite, alongside ground-dwelling fauna like the Oriental Rat Snake. Even less conspicuous species like the Two-striped Telamonia spider offered important glimpses into habitat health and complexity.

Invertebrates and pollinators like the Asian Green Mussel and Giant Honey Bee further added to the species list, highlighting the intricate interdependence of flora and fauna within this biodiverse landscape.

The initiative not only expanded our scientific understanding but also fostered community engagement, empowering locals to observe and appreciate the living systems around them. These biodiversity snapshots remind us that Puducherry’s natural heritage is not just rich — it’s living, dynamic, and in need of continuous care.
