Otter threat lurks on Kottayam's riverbanks
The number of otters in the Meenachil river and its tributaries has reached alarming proportions, instilling fear among those living along the banks. With an increasing number of otter bite incidents being reported, residents are now urging the government to take immediate steps to control their population.
Most affected areas
The situation is especially dire in regions such as Vijayapuram, Kumarakom, Aymanam, Arpookkara, Thiruvathukkal, Kottayam town, and Thazhathangadi. A recent incident in Velur near Kottayam has brought the issue into stark focus. Nisani, 53, wife of Ibrahimkutty from Kalayamkary, Panampady in Velur, died after being bitten by a large otter while washing clothes near her home. Although her death is suspected to have been caused by a heart attack following an anti-rabies injection, the incident has left riverside residents terrified. Since then, routine activities like washing clothes or utensils in the river have become fraught with fear.
Beyond posing a danger to human safety, the ballooning otter population has wreaked havoc on local fish farmers. Despite installing protective nets around their ponds, farmers report significant losses as otters, often attacking in groups, breach defences and consume large quantities of fish.
Once a rare sight, otters are now commonly seen navigating the waterways, particularly in stretches between Poovathumood and Vattamood bridges and around Parampuzha. Forest officials have also confirmed an increase in otter activity along the Meenachil river and nearby streams, especially during the animals' breeding season when they become more aggressive.
Why population surge
The otter is classified as a 'vulnerable' species on the IUCN Red List, making poaching a punishable offense.
According to experts, the rise in otter populations across riverine systems can largely be attributed to the absence of natural predators. 'Until around 2000, hunting groups from Andhra Pradesh would visit Kerala's waterbodies in search of otters. But with the tightening of wildlife conservation laws, that practice came to an abrupt end,' noted A. Jaison, former head of Wildlife Biology at the Kerala Forest Research Institute (KFRI).
'Most practical solution'
Otters inhabit rivers with dense bankside vegetation, marshes, and rocky areas. While manipulation of habitats could serve as a temporary deterrent, Dr. Jaison recommends trapping as the only currently viable option for population control. 'Capturing and relocating the animals might be the most practical solution,' he said.
Aby Iype, district general secretary of the Karshaka Congress, has urged the government to officially classify otters as vermin. 'The otter menace is a serious threat not just to human life, but also to the livelihoods of those involved in aquaculture,' he pointed out.

Endangered South American tree ‘staying' on a college campus in Chennai
The surest way to lose something valuable is to persist in ignorance about its value. Viewed from an ecological viewpoint, Roughbark lignum-vitae (Guaiacum officinale) might not belong to these parts. But if one accorded natural history the place it deserves but is often denied, sometimes wilfully, this Roughbark lignum-vitae needs to be made welcome, felt at home in the handful of earth in Chennai it has claimed as its own. Exotic trees have become naturalised in their adopted landscapes and are readily identified. The Roughbark lignum-vitae has not achieved that level of familiarity in Chennai; there is just a scattering of them in the city. And this clutch needs to be zealously guarded as this tree is faced with dwindling numbers everywhere. It is rare not just in Chennai, but even in lands where it is considered native. According to IUCN, the tree is endangered, exploitation of the tree for its wood (said to have been the densest in the world) having reached the tipping point. 'A small evergreen tree native to South America, it is reported to have been introduced to our parts in the 16th century. It 'adoption' could have been the result of the ornamental value it brought to a landscape: it puts out striking bluish purple flowers that attract butterflies and has bright yellow-orange fruits. In Tamil, it is called seemai vairamaram,' says T.D. Babu, a member of the Chennai District Green Committee and a key member of tree conservation organisation Nizhal. Babu underlines its special features — 'considered densest and water-proof, this tree's has been used in ship building. Its resin and bark are said to have medicinal properties. These factors led to its commercial exploitation and dwindling numbers.' In light of the threat of extinction faced by this tree, one would expect more care to be given to the clutch of Roughbark lignum-vitae trees found in Chennai. One of them has the Queen Mary's College Campus for an address. Babu notes that the base of the tree has suffered damage, not natural but human-inflicted in the past. It also displays 'wounds' further up its gnarled frame — an amputated branch. Babu wants the state of the tree's precincts to reflect its preciousness. Currently, the earth it stands in is overrun with weeds. This is the status report about this tree at Queen Mary's College campus as on August 8, 2025. Besides, on that day, this Roughbark lignum-vitae was wearing a nameboard not meant for it; one erroneously identifying it as a Ficus benghalensis moraceae (banyan tree). Babu explains why this tree at Queen Mary's College should be placed within an impregnable hedge of protection. 'In Chennai we lost a huge Roughbark lignum-vitae tree in a private property, a perfume factory in Adyar. Another massive tree on Swamy Sivananda Salai . We are now left with this one near the canteen at Queen Marys College campus; another inside Rostrevor Gardens, a railways quarters Anna salai; one more large tree inside Kalaingnar Poonga on Radhakrishnan Salai. There is a young Roughbark lignum-vitae each at Kalakshethra campus in Thiruvanmiyur and Lady Willington Institute of Advanced Study in Education at Kamarajar Sala. Outside Chennai, twin Roughbark lignum-vitae trees are found on the campus of Tamil Nadu Agriculture University in Coimbatore.'

Top 5 most deadly crocodile species in the world
Crocodilians are some of the most ancient and threatening predators on Earth. These sluggish reptiles are often seen basking in the sun, but they also have another side to themselves as powerful ambush hunters capable of terrifying speed and strength in the water. While most species are shy and try to avoid humans, a few have a deadly reputation for their frequent and often fatal interactions with people. Crocodiles can be found in rivers, swamps, estuaries, and coastal waters across the globe. With a bite force that matches any animal on the planet and bodies adapted for precision, crocodilians don't need much to become dangerous. In certain parts of the world, where human settlements are found near their natural habitats, encounters can turn tragic, and some species are more responsible for these incidents than others. Here are 5 of the most dangerous crocodile species Nile crocodile The Nile crocodile is considered the most dangerous crocodile species in the world. Found across much of sub-Saharan Africa and Madagascar, these massive reptiles can reach lengths of nearly 20 feet and are responsible for an estimated 300 attacks on people each year, many of which are fatal. Their ambush tricks, territorial behaviour, and closeness to human settlements make them especially dangerous. Unlike some species that shy away from people, they openly end up encountering one. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Unsold 2021 Cars Now Almost Free - Prices May Surprise You Unsold Cars | Search Ads Learn More Undo Saltwater crocodile Saltwater crocodiles, or 'salties,' live across Southeast Asia, northern Australia, and nearby islands. These giants are the largest living reptiles, reaching over 20 feet and weighing up to 1,100 pounds. Though they prefer to remain hidden, when they attack, it's quick and deadly. According to the International Union for Conservation of Nature (IUCN), between 2000 and 2007, there were nearly 30 recorded attacks in Australia and Malaysia alone, and many of them were fatal. American crocodile While not as aggressive as the Nile or saltwater crocodile, the American crocodile still poses a threat. Native to southern Florida, Central America, and northern South America, it prefers brackish or saltwater habitats. Males grow up to 16.5 feet. According to CrocBITE, between 2008 and 2013, 90 attacks occurred, resulting in about 20 deaths. Though they usually feed on smaller animals, they can become aggressive, especially when provoked or during territorial disputes. Gharial The gharial is mainly identified with its long, slender snout filled with sharp teeth, which may look menacing, but it's actually not considered dangerous to humans. Found in the rivers of northern India and Nepal, this species feeds almost entirely on fish. According to Britannica, although it doesn't attack people, it has been observed feeding on corpses released into rivers during funerals, which contributes to myths around its behavior. At 12 to 15 feet long, it's still an impressive sight—but not one humans need to fear. American alligator Found throughout the Gulf Coast and southeastern US, the American alligator is more likely to defend itself than attack unprovoked. Adult males grow to 13–15 feet, and while attacks are rarer, they do happen, especially when people try to interact with or feed them.

Stunning Video Reveals The Secret Life Of Endangered Clouded Leopards In Northeast India
In a rare glimpse into the secretive world of one of Asia's most elusive big cats, Indian Forest Service officer Susanta Nanda recently shared a captivating video on social media platform X. The footage showcases a clouded leopard mother and her cubs navigating the dense rainforests of Northeast India, a region known for its rich biodiversity. Clouded leopards (Neofelis nebulosa) are classified as 'Vulnerable' by the International Union for Conservation of Nature (IUCN), with an estimated wild population of fewer than 10,000 individuals. These solitary and nocturnal felines are native to the forests of the Himalayan foothills, Northeast India, and Southeast Asia. Their elusive nature and dwindling numbers make sightings exceptionally rare, adding significance to this recent observation. "Elusive. Ethereal. Endangered. With barely 10,000 left in the wild & scattered sightings in NE India, the clouded leopard is our most secretive big cat. Here, a rare glimpse: a mother with her cubs, guardians of an ancient rainforest. A sight so rare that it's mythical," he wrote in the caption. Watch the video here: Elusive. Ethereal. Endangered. With barely ~10,000 left in the wild & scattered sightings in NE India, the Clouded Leopard is our most secretive big cat. Here, a rare glimpse — a mother with her cubs, guardians of an ancient rainforest. A sight so rare that it's mythical. — Susanta Nanda IFS (Retd) (@susantananda3) August 5, 2025 Nanda's video not only offers a rare visual of these majestic creatures but also underscores the importance of conservation efforts in preserving their natural habitats. The clouded leopard's survival is threatened by habitat loss, poaching, and human-wildlife conflict. Conservationists emphasise the need for transboundary wildlife corridors and protected areas to ensure the species' continued existence. This sighting serves as a poignant reminder of the delicate balance within our ecosystems and the critical role of conservation in safeguarding the planet's biodiversity.
