  • Description of the Species:
    • The sea slug is a small, hermaphroditic invertebrate, growing up to 7 mm in length, with a brownish-black colour and a ruby red spot at the hind end.
    • It has an internal shell and is usually found crawling in intertidal zones, leaving marks on sandy beaches.
  • Distribution: While species in this group are typically found in temperate regions of the Indo-Pacific, three species including Melanochlamys droupadi are known to be tropical.

India’s Leopard Population

Context: According to a report by the Environment Ministry of India, India’s leopard numbers rose by 8% from 12,852 in 2018 to 13,874 in 2022.

India’s Leopard Population Survey: Key Points

  • Population: The survey found 13,874 leopards across 20 Indian states, with
    • Madhya Pradesh has the highest count (3,907).
    • Maharashtra (1,985), Karnataka (1,879), and Tamil Nadu (1,070) also had significant populations exceeding 1,000 each.
  • Decline: While overall population is stable, some regions like
    • Uttarakhand: 22% decline attributed to poaching and human-animal conflict.
    • Unlike tigers, leopards are more adaptable and found outside protected areas, leading to higher mortality due to conflict with humans and livestock.
  • Regional Variations: The survey focused on 70% of leopard habitat (forest areas) and revealed:
    • Shivalik hills and Gangetic plains: 3.4% annual decline
    • Central India, Eastern Ghats, Western Ghats, Northeast hills, and Brahmaputra floodplains:5%, 1%, 1%, and 1.3% annual growth respectively
  • Increase: A significant increase (150% rise to 349) was reported in Arunachal Pradesh, Assam, and West Bengal.
    • The sharp rise in Northeast India might be due to more extensive sampling and camera traps compared to previous surveys.
  • Protected Areas: About a third of the leopards reside within protected areas, and tiger reserve conservation indirectly benefits leopards by preserving their habitat.
  • Methodology: The survey involved extensive efforts, with forest surveyors covering 6,41,449 km and analysing data from 4,70,81,881 photographs captured by camera traps at 32,803 locations.

What are Critical Minerals?

  • Critical minerals are mineral resources, both primary and processed, that are essential inputs in modern technologies, economies, and national security.
  • They are characterised by the risk of supply chain disruption due to non-availability and price volatility.
  • These minerals play a crucial role in various industries and sectors and have limited substitutes, making them of strategic importance.
  • India’s Identified Critical Minerals: An Expert Committee under the Ministry of Mines in India has pinpointed 30 minerals as critical for the country.
    • These include minerals like Antimony, Beryllium, Bismuth, Cobalt, Copper, Gallium, and Germanium.
