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.

Do you really need to use that plastic straw?

The hazards of single-use plastic items, and what to use instead.

In June 2018, a distressed whale in Thailand made headlines around the world. After an autopsy it’s cause of death was determined to be more than 80 plastic bags it had ingested. The pictures caused great concern and brought into focus the urgency of the fight against single-use plastic. This term refers to use-and-throw plastic products that are designed for one-time use, such as takeaway spoons and forks, polythene bags styrofoam cups etc. In its report on single-use plastics, the United Nations Environment Programme (UNEP) has described how single-use plastics have a far-reaching impact in the environment.

Dense quantity of plastic litter means sights such as the distressed whale in Thailand aren’t uncommon. Plastic products have been found in the airways and stomachs of hundreds of marine and land species. Plastic bags, especially, confuse turtles who mistake them for jellyfish - their food. They can even exacerbate health crises, such as a malarial outbreak, by clogging sewers and creating ideal conditions for vector-borne diseases to thrive. In 1988, poor drainage made worse by plastic clogging contributed to the devastating Bangladesh floods in which two-thirds of the country was submerged.

Plastic litter can, moreover, cause physiological harm. Burning plastic waste for cooking fuel and in open air pits releases harmful gases in the air, contributing to poor air quality especially in poorer countries where these practices are common. But plastic needn’t even be burned to cause physiological harm. The toxic chemical additives in the manufacturing process of plastics remain in animal tissue, which is then consumed by humans. These highly toxic and carcinogenic substances (benzene, styrene etc.) can cause damage to nervous systems, lungs and reproductive organs.

The European Commission recently released a list of top 10 single-use plastic items that it plans to ban in the near future. These items are ubiquitous as trash across the world’s beaches, even the pristine, seemingly untouched ones. Some of them, such as styrofoam cups, take up to a 1,000 years to photodegrade (the breakdown of substances by exposure to UV and infrared rays from sunlight), disintegrating into microplastics, another health hazard.

More than 60 countries have introduced levies and bans to discourage the use of single-use plastics. Morocco and Rwanda have emerged as inspiring success stories of such policies. Rwanda, in fact, is now among the cleanest countries on Earth. In India, Maharashtra became the 18th state to effect a ban on disposable plastic items in March 2018. Now India plans to replicate the decision on a national level, aiming to eliminate single-use plastics entirely by 2022. While government efforts are important to encourage industries to redesign their production methods, individuals too can take steps to minimise their consumption, and littering, of single-use plastics. Most of these actions are low on effort, but can cause a significant reduction in plastic waste in the environment, if the return of Olive Ridley turtles to a Mumbai beach are anything to go by.

From microplastics in cosmetics to haunting art on plastic pollution, Planet or Plastic is a comprehensive resource on the problem.
