Dolomedes Indicus: New Spider Species from Western Ghats

Introduction
- Dolomedes indicus is a newly identified spider species discovered in the evergreen rainforests of the Western Ghats, specifically in Wayanad, Kerala.
- It is the first recorded species of the Dolomedes genus (raft/fishing spiders) described from India.
Key Characteristics
- Belongs to a group of semi-aquatic predators that actively hunt instead of using webs.
- Uses surface tension of water to detect vibrations from insects or small fish.
- Capable of rapid movement across water, swimming, and even diving to capture prey.
- Males exhibit a distinct snow-white marking running from the face to the centre of the back.
- Females are larger, with greenish-brown coloration that blends with mossy streamside habitats.
Habitat & Ecology
- Found in pristine, cool freshwater streams under dense forest canopies.
- Highly environment-sensitive species, requiring undisturbed ecosystems for survival.
- Occurs in ecologically fragile areas of the Western Ghats biodiversity hotspot.
Behavioural Adaptations
- Hunts by resting legs on water surface to sense prey vibrations.
- Displays high agility, enabling sudden leaps across water films.
- Part of broader freshwater stream communities, feeding mainly on aquatic and semi-aquatic organisms.
Conservation Significance
- Its presence indicates healthy freshwater ecosystems with minimal pollution.
- Serves as a bioindicator species, helping monitor environmental changes in rainforest streams.
- Discovery highlights the importance of conserving microhabitats within the Western Ghats.
- Reinforces need for aquatic biodiversity assessments in India’s rainforest systems.

Afar Region: A Geological Marvel

Location & Physical Setting
- The Afar region lies in northeastern Ethiopia, where the Red Sea meets the Gulf of Aden.
- Includes the Afar (Danakil) Depression, one of the hottest and lowest places on Earth.
- Characterised by desert scrublands, shallow saline lakes, sulphur fields, and volcanic chains.
Geological Significance
- Represents a rare triple tectonic junction where the Red Sea Rift, Gulf of Aden Rift, and East African Rift intersect.
- Landscape features deep rift valleys, fissures, volcanic plateaus, and active tectonic deformation.
- Provides scientists a unique opportunity to study continental breakup and the early stages of ocean formation.
Hydrological Features
- The Awash River Valley forms the southern part of the region, influencing settlement patterns.
- Contains hypersaline lakes formed by evaporation under extreme aridity.
Paleoanthropological Importance
- Globally renowned for early hominid fossils, notably “Lucy” (Australopithecus afarensis) discovered in 1974.
- Offers insights into human evolution and environmental adaptation.
Environmental Conditions
- Among Earth’s most extreme environments due to high temperatures and volcanic activity.
- Frequent tectonic movements reshape the terrain, creating evolving landscapes.
