Karnataka is “One State Many Worlds, without a doubt! To explore a different aspect of travelling through this beautiful state, I take you on a path that is en-Lightening, in literal sense- ‘Bioluminescence’. Bioluminescence is a naturally occurring phenomenon of production and emission of light in living organisms. Apart from the visual treat to senses that they offer, the presence of these organisms can tell a lot about our environment as well.
With the Arabian Sea forming the entire coastal belt and the Western Ghats forming most of the green-cover of Karnataka, it is easy to witness bioluminescence anywhere in the state. Traversing a path from the southern rainforests of the state to the northern plainlands through the coastal beaches across all the seasons, here is a list of the different kinds of bioluminescence that one can experience in Karnataka.
- Fireflies: An aerial illumination for spectators, these insects produce light to attract a potential mate. Abundant during the months of pre-monsoon showers and summers, the untouched sacred groves and the organic farms of Kodagu and Malenadu offer a post sunset visual delight. A good number of fireflies indicates the good soil and air quality.
- Bioluminescent planktons: These light emitting micro-organisms are present in the sea water. They produce a greenish-blue light when disturbed. This means, they produce light irrespective of day or night but can be seen with normal eyes after dark. These glowing waters can be viewed at their brightest best on a no-moon night between two consecutive monsoon months. But what is not the brighter about it is the fact that the brighter the sea glows due to these planktons, the poorer is the health of the sea water.
- Bioluminescent fungi: This can be the hardest find of them all. Enter the core of the rainforest during the peak of the monsoon season, with a slow and careful walk and without use of any torch or flashlights. Only if you are lucky, you can spot these glowing sticks or the fallen barks covered by the glowing fungi. Documented sightings have been found in Karnataka, but I’m sure the Western Ghats are home to more species of luminant mushrooms.
- Glow worms: These are larvae of some insects that can be largely found along the banks of streams, rivers and under the foliage on moist ground. An indication of healthy soil, these worms emit light to ward off predators and visually offering a delight to the human eyes.
