The magnificent Lakshadweep archipelago, made up of coral reefs and atolls, lies around 420 km west of the coast of Kerala. Its clear waters offer exceptional underwater visibility, and on any ordinary dive, you will find its reefs rife with activity.

Schools of paddletail snappers, several hundred strong, nudibranchs grazing on their favourite patch of algae, butterflyfish roaming in pairs, nibbling on coral, or large groupers swimming boldly through the reef.

What is less frequently seen is the flip side—the reef after dark. As the sun sets, the vibrant visuals of the reef subside, and many fish cease activity and nestle into coral crevices for shelter.

Moonlight trickles through the sea, sieved by its surface, creating a shifting pattern on the shallow reef. In this dim light begins the nightlife of the reef.

Some branching endlessly outwards, some as flat as tabletops, Acropora coral were once a common sight in the Andamans.

The 180 species of Acropora are a haven for all kinds of marine life. Damselfish find shelter within, dancing around their branches; hawkfish and anthia use them as safe hideouts when not searching for prey.

However, in recent years, repeated bleaching episodes have threatened this ubiquitous and important genus of coral. Chetana Babburjung Puroshottam reports observing them in severe decline and then suddenly bouncing back in 2020 around the time of the COVID-19 pandemic. Where she was used to seeing bleached 'graveyards,' she now saw a sea of Acropora in the shallows. Sadly, this would not last—come 2023, prolonged ocean warming would turn these corals a ghostly white once again.

The Indian Ocean is one of the youngest, smallest oceans in the tropics, and it's landlocked in the north, unlike the Atlantic and Pacific, where water flushes freely toward the poles. That means heat gets trapped, making it also the warmest ocean basin on Earth.

But the last few years, global warming has pushed the Indian Ocean into a constant state of crisis. With another El Niño event just around the corner, what does this mean for our oceans and human and wild lives that depend on it.

Turns out, the future belongs to generalists. Even frogs saw it coming.

As humans race to specialise in AI, cities keep expanding, and apparently the frogs are the ones who figured out how to survive it all.

We are thrilled to announce that our film 'A Spring Against All Odds' is an official selection at the 15th edition of Film SouthAsia taking place from 26-29 November 2026 in Kathmandu.

About the film:
A Spring Against All Odds
In the middle of the pandemic, just short of spring, a couple moves into a new home in Delhi to live beside a tree. As the city and life, hurtle from crisis to crisis — a mismanaged pandemic, a winter thick with pollution, a monsoon of floods, an oppressive summer, a political shift, a personal loss — the tree becomes a constant, and soon an obsession.
