Photos: This shy Indian viper may finally get more admirers because of the efforts of a Goa group

Shyness coupled with a small range make the Malabar Pit Viper difficult to research.

The Malabar Pit Viper is unique for a couple of reasons: one, it is endemic to the eco-sensitive coastal region of Western India, and is found nowhere else in the world. Two, this shy creature is absolutely stunning and a treat to spot.

Herpetologist, wildlife photographer and Malabar pit viper-fan Nirmal Kulkarni founded Herpactive, a conservation-driven organisation run by a team of qualified herpetologists, in 2010. Kulkarni and his team aim to create awareness about and instil appreciation for Herpetofauna (reptiles and amphibians) of Goa in particular, and the country in general.

Herpactive held a photo exhibition dedicated to the Malabar Pit Viper from July 14 to July 16 at the Art and Culture Department in Panjim, Goa. The organisation has also been working to build the impetus of research projects directed at studying the Malabar Pit Viper.

Known to exhibit seven colour morphs or forms, a rare evolutionary trait among snake species, the Malabar Pit Viper is found in shades of yellow, green and brown, as well as several combinations and patterns of these colours.

Morphology is an organism’s response to its surroundings. In Malabar Pit Viper’s case, the kind of colour morph it belongs to is indicative of whether it is found in areas with deciduous vegetation and bare, rocky surfaces, or in regions of dense undergrowth and evergreen vegetation. Like all snakes, it is colour blind and yet, fascinatingly, has the evolved into these seven distinct colour morphs in order to camouflage itself.

There is little research to help understand the behaviour of the Pit Viper. Its inherent shyness coupled with the fact that its range is restricted to a relatively small habitat, makes it difficult to study without sufficient funding and manpower.

“At the moment our organisation doesn’t have any staff or researchers dedicated solely to observing and recording the habits of this snake,” said Kulkarni. Instead, the people at Herpactive organise guided walks, surveys, training workshops and field technique sessions for budding herpetology enthusiasts. “It is crucial for the community that studies herpetofauna in India to know more about this species, in order to gain deeper perspective on the delicate ecology of the Western Ghat region,” said Kulkarni.

The Malabar Pit Viper is not a very large snake – adult males average 105 centimetres from snout to tail, with females being significantly larger. Their prey includes small vertebrates like rats and frogs and the monsoon is an ideal time to track these vipers, as their prey base expands with the coinciding frog spawning period.

An interesting aspect of the Pit Viper’s behaviour, according to Kulkarni, is that if it finds a suitable place to find prey or a mate, it can stay in the same spot for days, often weeks. “An intern assigned to studying the herpetofauna of the Mhadei Wildlife Sanctuary has been recording an individual that has been in the same spot for 38 days,” said Kulkarni.

Maintaining a high level of biodiversity is important to all life on Earth, including humans, and snakes are an important part of that biodiversity. Snakes and other reptiles make up a substantial proportion of the middle-order predators that keep our natural ecosystems working. Without them the number of prey species would increase to unnatural levels.

In an effort to bridge the gap between enthusiasts and experts, herpetologists all over India have made efforts to integrate lay people into snake conservation programmes. In an additional push at connecting budding naturalists, dispelling myths about snakes and promoting the cause of conservation, Kulkarni will be conducting a talk at the Museum of Goa on July 23. The talk will be centred on the Malabar Pit Viper and some of the photographs from the exhibition (taken by 32 well-known nature photographers and conservationists) will be on sale at the venue.

Some of the most significant innovations in automotive history made their debut in this iconic automobile

The latest version features India's first BS VI norms-compliant engine and a host of 'intelligent' features.

The S-Class, also known as Sonderklasse or special class, represents Mercedes Benz’ top-of-the-line sedan line up. Over the decades, this line of luxury vehicles has brought significant automotive technologies to the mainstream, with several firsts to its credit and has often been called the best car in the world. It’s in the S-Class that the first electronic ESP and ABS anti-lock braking system made their debut in the 20th century.

Twenty first-century driver assistance technologies which predict driver-behaviour and the vehicle’s course in order to take preventive safety measures are also now a staple of the S-Class. In the latest 2018 S-Class, the S 350 d, a 360-degree network of cameras, radars and other sensors communicate with each other for an ‘intelligent’ driving experience.

The new S-Class systems are built on Mercedes Benz’s cutting-edge radar-based driving assistance features, and also make use of map and navigation data to calculate driving behaviour. In cities and on other crowded roads, the Active Distance Assist DISTRONIC helps maintain the distance between car and the vehicle in front during speeds of up to 210 kmph. In the same speed range, Active Steering Assist helps the driver stay in the centre of the lane on stretches of straight road and on slight bends. Blind Spot Assist, meanwhile, makes up for human limitations by indicating vehicles present in the blind spot during a lane change. The new S-Class also communicates with other cars equipped with the Car-to-X communication system about dicey road conditions and low visibility due to fog, rain, accidents etc. en route.

The new S-Class can even automatically engage the emergency system when the driver is unable to raise an alarm. Active Emergency Stop Assist brings the car to a stop if it detects sustained periods of inactivity from the driver when Active Steering Assist is switched on. If the driver doesn’t respond to repeated visual and audible prompts, it automatically activates the emergency call system and unlocks the car to provide access to first responders.

The new Mercedes-Benz S 350 d in India features another notable innovation – the country’s first BS VI norms-compliant car engine, in accordance with government regulations to control vehicular pollution. Debuting two years before the BS VI deadline of 2020, the S 350 d engine also remains compatible with the current BS IV fuels.

The S 350 d is an intelligent car made in India, for Indian roads - in the Mercedes Benz S-Class tradition. See the video below to know what drives the S-Class series by Mercedes Benz.
