Prelims level: Squalus hima
Why in the News?
Scientists from the Zoological Survey of India (ZSI) have discovered a new species of deep-water dogfish shark, Squalus hima, from the Sakthikulangara fishing harbour in Kerala along the Arabian Sea.
About Squalus hima
Squalus is a genus of dogfish sharks in the family Squalidae, commonly known as spurdogs, characterized by smooth dorsal fin spines.
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.
Dogfish sharks are commercially important for their fins, liver oil, and meat and are sometimes caught as by-catch in fisheries targeting other species.

About Great Indian Bustards
GIBs are the largest among the four bustard species found in India, the other three being MacQueen’s bustard, the lesser florican, and the Bengal florican.
GIBs’ historic range included much of the Indian sub-continent but it has now shrunken to just 10 percent of it.
Among the heaviest birds with flight, GIBs prefer grasslands as their habitats.
GIBs are mainly found in Desert National Park, Rajasthan.
Bustards face major threats, including habitat changes and collisions with power lines.
Protection accorded:
Birdlife International: uplisted from Endangered to Critically Endangered (2011)
Protection under CITES: Appendix I
IUCN status: Critically Endangered
Protection under Wildlife (Protection) Act: Schedule I
What is the GIB Recovery Plan?
The proposal was prepared by the Wildlife Institute of India (WII).
The proposal includes:
Rewilding Bustards bred in ex-situ conservation centres,
Conducting detailed population studies, and
Developing artificial insemination techniques.
Back2Basics: Wildlife Institute of India (WII)
WII is an autonomous institution under the Ministry of Environment, Forest and Climate Change.
It was established in 1982.
It is based in Dehradun, Uttarakhand.
Functions: It offers training programs, academic courses, and advisory in wildlife research and management.
Why such a move?
Indicator Species: The GIB is a key indicator species of grassland habitat, signalling the health of these environments.
Population Decline: The population has declined from around 700 individuals to less than 150 due to habitat loss, predation, and death by overhead power lines.
Supreme Court Order: The Supreme Court recognized the threat from power lines and constituted an expert committee to assess the feasibility of overhead and underground electric lines in the bustard’s habitats.
Conservation Efforts and Achievements
Recovery Plan: Initial efforts began between 2012-2013 with a long-term recovery project, which firmed up in 2016 with a Rs 33.85 crore funding outlay.
Funding and Agreements: The project was funded by the Compensatory Afforestation Fund, with a tripartite agreement in 2018 involving the Environment Ministry, Rajasthan Forest Department, and WII.
In-Situ Breeding: Conservation breeding began in 2019, resulting in a founder population of 40 GIBs at the Ramdevra centre.
Achievements at Breeding Centres
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.

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 snakesor 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:
They have smooth, cylindrical bodies with a ringed or striped pattern, hence the name “striped.”
Caecilians are predominantly fossorial (burrowing), spending most of their lives underground or in leaf litter. This behaviour makes them elusive and difficult to study.
They are carnivorous, feeding on small invertebrates found in soil and leaf litter.
Their eyesight is generally poor, and they rely on chemoreception (sensing chemicals in the environment) to locate prey.
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.

Prelims level: North Atlantic Right Whales
Mains level: NA
Why in the news?
North Atlantic right whales face a grave threat due to entanglementin fishing gear, contributing to their critically endangered status.
Entanglement not only leads to physical harm but also affects reproductive success, exacerbating the species’ decline.
Impact of Entanglement
Lethal and Sublethal Effects: Entanglement in fishing gear leads to energy expenditure, reduced feeding efficiency, and physical injuries, ultimately impacting whales’ ability to reproduce and survive. Even minor entanglements have devastating consequences on female right whales.
Reproductive Implications: Females experiencing entanglement events, even classified as “minor,” exhibit reduced breeding rates, with potential long-term consequences for population recovery. Poor health and physical condition further impede breeding success.
About Right Whales
Right whales are a group of large baleen whales belonging to the family Balaenidae.
There are three species of right whales:
North Atlantic right whale (Eubalaena glacialis),
North Pacific right whale (Eubalaena japonica), and
Southern right whale (Eubalaena australis).
They are distinguished by their geographic distribution and slight differences in physical characteristics.
Right whales inhabit temperate and subpolar waters of the North Atlantic, North Pacific, and Southern Hemisphere.
They are often found in coastal areas during their feeding and breeding seasons but may migrate over long distances.
All three species of right whales are listed as endangered or critically endangered by the International Union for Conservation of Nature (IUCN).
North Atlantic Right Whales
It is listed as Critically Endangered in the IUCN Red List.
Only around 360 individuals remain, with almost 90% having experienced entanglement at least once.
