Why in news: Bengaluru corporations are examining legally permissible options for euthanizing 'rabid, ill, or aggressive' dogs following a Supreme Court ruling.
The Supreme Court allows euthanasia only for dogs that are 'rabid, incurably ill, or demonstrably dangerous' subject to qualified veterinary assessments. Animal rights activists and co-petitioners have raised concerns over the lack of clear guidelines on defining 'aggression levels'.
Prelims pointers (2)
FactEuthanasia is permitted only for dogs classified as rabid, incurably ill, or demonstrably dangerous.
FactThe ruling mandates qualified veterinary assessments before any euthanasia procedure.
Mains angle
Q. Discuss the conflict between public safety and animal rights in urban stray dog management. How can a balanced regulatory framework be established?
Regulatory ambiguity: Lack of standardized metrics for 'demonstrably dangerous' behavior leads to potential arbitrary enforcement.
Ethical-Legal conflict: Balancing the constitutional right to life/safety with animal welfare protections under existing laws.
Why in news: Scientists from Mizoram University and Max Planck Institute described a new snake species, Trachischium lalremsangai, found in Mizoram and Myanmar.
The new species, Trachischium lalremsangai, was named after herpetologist Hmar Tlawmte Lalremsanga. Specimens were collected from Murlen National Park in Mizoram and Haka Township in Myanmar.

Q. Discuss the ecological and geological risks associated with large-scale hydroelectric projects in seismically active Himalayan regions like the upper Ganga.
Seismic risk: Potential for dam failure or triggered landslides in the Himalayan seismic zone
Ecological degradation: Cumulative impact of multiple dams on the Ganga's riverine ecosystem and biodiversity
Flood dynamics: Alteration of natural river flow patterns increasing downstream flooding risks
Why in news: CMFRI researchers documented the first evidence of both heterosexual and homosexual mating behavior in the Indian squid (Uroteuthis duvaucelii) in the Arabian Sea.
The study analyzed 232 female squids from the Arabian Sea off Kochi. Researchers identified active mating throughout the year with peak activity in October and found spermatangia on a male squid, indicating same-sex sexual behavior.

Why in news: Union Environment Minister Bhupendra Yadav announced that satellite-tagged Amur falcons, which spent four months in southern Africa, have begun their spring migration back to the Far East via India.
Two of three Amur falcons tagged in Manipur's Tamenglong district in November 2025 are being tracked. The birds are currently crossing the Arabian Sea from Somalia, with one falcon named 'Alang' expected to reach India's west coast.
