Dugesia Punensis
A groundbreaking discovery was made in Pashan Lake, Pune. A new species of planarian worm, named Dugesia punensis, was identified. This marks the first new planarian species recorded in India since 1983. The findings were published in the Records of the Zoological Survey of India.
Characteristics of Dugesia Punensis
- Dugesia punensis is a freshwater flatworm known for its remarkable regenerative abilities.
- This species measures between 8mm and 12mm in length.
- Its dorsal side is dark brown with a spotted appearance, while its ventral side is pale.
- The flatworm features slightly reduced auricles, an elongated pharynx, and gonopore.
- Its eggs are circular and reddish in colour. Auricular grooves surround two prominent black eyes.
Regeneration Capabilities
One of the most notable features of Dugesia punensis is its capacity for regeneration. The flatworm can completely regrow after starving for 15 to 20 days, demonstrating full regeneration within 10 to 13 days. This extraordinary ability makes it a subject of interest in biological research, particularly in the fields of regeneration and developmental biology.
Habitat and Ecological Importance
Pashan Lake is situated within the Western Ghats biodiversity hotspot. This wetland serves as a vital habitat for endemic species, including Dugesia punensis. The study emphasises the ecological significance of Pashan Lake and marks the need for conservation efforts to protect its unique biodiversity.
Research Methodology
The research involved collecting, culturing, and analysing specimens of Dugesia punensis. Researchers employed morphological and molecular phylogenetic methods to classify the species. The study contributes to the taxonomy and phylogeny of the Dugesia genus, expanding our understanding of planarian diversity.
