Kali River goonch attacks

Kali River goonch attacks is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kali River goonch attacks rather than just read about it. In short: The Kali River goonch attacks were a series of fatal attacks on humans believed to be perpetrated by a goonch weighing 90 kilograms (200 lb) in three villages on the banks of the Kali River in India and Nepal, between 1998 and 2007. This is the subject of a TV documentary aired on 22 October 2008, as well as an episode about the Kali River goonch attacks on the Animal Planet series River Monsters.

Key takeaways

  • Kali River goonch attacks belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kali River goonch attacks to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kali River goonch attacks from memory before moving on to harder problems.

Reference excerpt

The Kali River goonch attacks were a series of fatal attacks on humans believed to be perpetrated by a goonch weighing 90 kilograms (200 lb) in three villages on the banks of the Kali River in India and Nepal, between 1998 and 2007. This is the subject of a TV documentary aired on 22 October 2008, as well as an episode about the Kali River goonch attacks on the Animal Planet series River Monsters.

Attacks The first attack occurred in April 1998, when at 13:00, 17-year-old Dil Bahadur, while swimming in the river, was dragged underwater in front of his friend and several eyewitnesses. No remains were found, even after a three-day search spanning 5 kilometers (3.11 miles). Three months later, at Dharma Ghat, a young boy was pulled underwater in front of his father, who watched helplessly. No corpse was ever found. The final attack occurred in 2007 when an 18-year-old Nepalese man disappeared in the river, dragged down by something described as a mud-colored "water pig".

Investigation

British biologist Jeremy Wade volunteered to capture the perpetrator. Though originally skeptical of the truth behind the attacks, he later became intrigued because the attacks only occurred in a specific area spanning 6.4 kilometres (4 mi). He was told by the villagers that the creature likely developed a taste for human flesh and had grown large after eating half-burnt human remains discarded from funeral pyres on the river banks. After examining the water where Bahadur had disappeared with a depth sounder, Wade discounted the possibility of the boy having been dragged by a whirlpool, as the attacks all occurred in areas without turbulence. Later, one kilometre (0.62 mi) away, a domestic water buffalo was reportedly dragged underwater by a strange animal while drinking in water only one metre (3 ft 3 in) deep. Wade theorised that the creature would have had to weigh 91–136 kilograms (200–300 lb) in order to do so. A buffalo weighs 300–400 kilograms (660–880 lb), according to the film.

All three species of crocodile possible in the area were dismissed: saltwater crocodiles are not known to travel so far inland; the jaw structure of gharials prevents them from killing humans or buffalo; and mugger crocodiles, the most common Indian species, do not inhabit the cold torrents of the Kali River. Also, crocodiles had never been seen on land to bask or breed. Although bull sharks were initially considered, an underwater investigation by marine biologist Rick Rosenthal in the area where the buffalo disappeared yielded no sightings of bull sharks. Further, Wade believed that bull sharks would not have lived so far upriver, and there had been no sightings of dorsal fins breaking the water's surface. However, during the underwater investigation, a 1-metre (3 ft 3 in) goonch catfish was sighted, which Wade unsuccessfully tried to capture. Later underwater investigations yielded numerous group sightings of goonch, six of which were man-sized. After an unsuccessful attempt was made at capturing one with a fishing rod, a funeral pyre was set up in order to lure one in. A record-breaking 1.7-metre (5 ft 7 in), goonch was captured the day after, and was weighed at 73 kilograms (161 lb), three times the weight of an average goonch. Although Wade estimated that the fish was strong and large enough to eat a small child, he stated in an interview that he believed that larger specimens were likely to exist, and that the specimen he captured was not large enough to be the alleged maneater, on the basis of the sizes of the victims. These events were shown on his program River Monsters.

Worked examples

Example 1 — a first encounter with Kali River goonch attacks

Start with the simplest possible case. Write down what Kali River goonch attacks claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kali River goonch attacks before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kali River goonch attacks ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kali River goonch attacks

In research
Kali River goonch attacks appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kali River goonch attacks in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kali River goonch attacks is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1998 in India, 1998 in Nepal, Deaths due to fish attacks, so understanding it makes those chapters shorter.
In everyday life
Look for Kali River goonch attacks outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
