Researchers from the Zoological Survey of India (ZSI) discovered a new species of deep-water dogfish, Squalus Hima, at the Sakthikulangara fishing harbour, Kerala.
Squalus Hima has distinctive smooth spines on its dorsal fins, setting it apart from other species.
The species was meticulously described based on 13 specimens, highlighting the scientific rigor involved.
Squalus Hima is differentiated from closely related species like S mitsukurii and S lalannei by vertebrate count, teeth number, and fin shape.
Dogfish sharks are threatened by overfishing for their meat, liver oil, and fins, emphasizing the need for conservation.
Dogfish sharks inhabit depths from 3,000 feet to shallower waters and can live for over 40 years.
As keystone predators, dogfish sharks help maintain marine ecosystem balance by controlling prey populations.
Like other marine animals, dogfish sharks are adversely affected by pollution, further threatening their survival.
