    • The new species, Squalus hima sp. nov., has been misidentified with S. mitsukurii and S. lalannei in the past.
    • Squalus hima differs from other species by the number of precaudal vertebrae, total vertebrae, teeth count, trunk and head heights, fin structure, and fin colour.

    Comparison with Other Species

    • On the Indian coast, two species of Squalus are found from the southwest coast of India.
    • The new species, Squalus hima n.sp., is very similar to Squalus lalannei but differs in many characteristics.
    • Species in the Squalus megalops group are characterized by an angular short snout, a small mouth almost as wide as the snout, the first dorsal fin origin behind the pectoral fins, and a body without any spots.

    Economic and Conservation Implications

    • Sharks in the genus Squalus and Centrophorus are exploited for their liver oil, which contains high levels of squalene, used in high-end cosmetic and anti-cancer products.
    • Fishermen from southern India and the Andaman and Nicobar Islands harvest these sharks for their liver oil, making conservation of these species critical.

    Importance of the Discovery

    • The discovery of Squalus hima is significant for the conservation of shark species exploited for commercial purposes.

    • Successful Breeding: Eggs collected from the wild were incubated and chicks were hand-reared. The breeding centres now have a founder population of 40 GIBs.
    • Scientific Reasoning: Creating a founder population prevents extirpation and captures genetic variability. The goal is to have at least 20 adult birds including 15 females.

    Future Plans

    • Next Phase (2024-2033): The immediate next phase will run until 2029, targeting the upgradation of the CBC at Ramdevra and the development of the Lesser Florican CBC at Sorsan.
    • Population Surveys: Surveys will be conducted in Rajasthan and other range states to monitor population status.
    • Release into the Wild: The most important target is releasing captive-bred GIBs into the wild, preceded by soft release in enclosures.

    Why in the News?

    • A limbless amphibian, the striped caecilian (Ichthyophis spp), has been newly identified within the 1,307.49 sq. km Kaziranga National Park and Tiger Reserve.
      • Assam’s wildlife officials reported its discovery during a herpetofauna survey.

    Back2Basics: Herpetofauna

    • Herpetofauna refers to a group of reptiles and amphibians collectively.
    • The term combines “herpeto-” from the Greek “herpeton,” meaning “creeping animal,” and “fauna,” referring to the animal species found in a particular region or time.
    • Herpetofauna play essential roles in ecosystems:
      • They act as both predators and prey, help regulate insect populations, and serve as indicators of environmental health.
      • They serve as environmental indicators and play significant roles in pest control.

    About Striped Caecilian

    • The Striped Caecilian (Ichthyophis spp.) is a type of limbless amphibian belonging to the family Ichthyophiidae.
    • Caecilians are often mistaken for snakes or worms due to their elongated, cylindrical bodies and lack of limbs.
    • They are primarily found in tropical regions of Africa, Asia, and the Americas.
    • They usually live underground or in moist soil habitats.

    Key features of the Striped Caecilian include:

    1. They have smooth, cylindrical bodies with a ringed or striped pattern, hence the name “striped.”
    2. Caecilians are predominantly fossorial (burrowing), spending most of their lives underground or in leaf litter. This behaviour makes them elusive and difficult to study.
    3. They are carnivorous, feeding on small invertebrates found in soil and leaf litter.
    4. Their eyesight is generally poor, and they rely on chemoreception (sensing chemicals in the environment) to locate prey.
    5. Caecilians are known for their unique reproductive strategies, which can involve live births or laying eggs. Some species exhibit parental care, with adults guarding eggs or young offspring.

    Significance: Kaziranga’s Biodiversity

    • Kaziranga National Park’s diverse ecosystem, encompassing flood plains, wetlands, grasslands, and hill tracts, provides an ideal habitat for herpetofauna.
    • The park hosts 24 amphibian species, 74 reptile species, and 21 of India’s 29 species of tortoises and freshwater turtles.

    • Larvae of the moth Bucculatrix crateracma feed on its leaves.
    • The golden-crowned sparrow weaves the lining of its nests with white cotton from its seeds.

    Felling of a Semal Tree: Which laws are violated?

    1. Rajasthan Forest Act 1953: This act prohibits various activities in reserved forests without prior permission. Specifically, it bars any unauthorized person from felling, uprooting, damaging, or otherwise harming trees. Violating these prohibitions can lead to penalties including imprisonment, fines, or both, depending on the severity of the offence. Semal tree is not recorded in the state’s list of ‘rare, threatened, and endangered’ species. (Trees on this list enjoy priority conservation efforts.) (Indian Kanoon)​
    2. Forest (Conservation) Act 1980: This act is more comprehensive at the national level and was enacted to provide for the conservation of forests and to regulate deforestation. It requires that any non-forest use of forest land must have prior approval from the Central Government. This includes clearances for felling trees, which are only granted under specific conditions that ensure the conservation and sustainable use of forest resources.​ (UNEPLawEnvAssistantPlat)​
