Among the 36 Lakshadweep islands dotting the Indian Ocean, one is particularly famous for its bird life. Pakshi Pitti is a flat sandbar that several species of seabirds come to for breeding. Devoid of predators such as rats and cats, and even humans, it is the perfect place for these birds to nest in.
Except, year after year fisherfolk from the nearby populated island of Kavaratti come to Pitti and plunder its wealth of seabird eggs. On every visit they make, they collect 14%–45% of the eggs. About 72% of the islanders of Kavaratti are involved in poaching and trading eggs from Pitti, showing that the network is quite vast.
The eggs are sought for their supposed medicinal properties, and their trade, scientists fret, could have a huge impact on the island’s seabirds, especially terns, whose numbers have plummeted from 20,000 in the mid-1900s to 970 in 2014.
Pitti was declared a bird sanctuary and afforded legal protection to stop this age-old practice of egg consumption. But a lack of regulation is defeating that purpose.

Deepak Veerappan was in-between research jobs when, out of boredom, he started exploring the parched open lands in the south and west of India. He ventured out on his own into sun-baked landscapes in search of a “fan-throated lizard” – a small lizard with a large double chin. His post-doctoral position at the Indian Institute of Science, and thus funding, were yet to come but he had already laid the foundation of what would keep him busy for the next few years.
Only two species of the unusual lizards Veerappan loved watching had been known from India. From observing them in the wild, he knew there were actually more than two. This led Veerappan to discover five new species of fan-throated lizards – named so because the males have loose, stretchable skin hanging from their necks.
This spectacular find is one among a slew of discoveries we have seen so far this year in India. Wherever you look, be it the shores in the south or mighty mountains in the north, sun-scorched lands of the west or wet hills of the east, new species are being found everywhere. And yet scientists say there’s more to come. What on earth is going on?
Five new species of brightly coloured freshwater crabs have been found in the Western Ghats, India’s wildlife haven. Of these, two species belong to the genus Ghatiana (discovered in 2014) and the remaining to Gubernatoriana (known since 1970).
Behind the discoveries are an undergraduate student and researchers from the Zoological Survey of India and the Indian Herpetological Society. They described the five new species, named Ghatiana atropurpurea, Ghatianasplendida,Gubernatorianathackerayi, Gubernatorianawaghi, and Gubernatorianaalcocki, in the journal Zootaxa on February 23.
Prior to this, 36 species belonging to 14 different genera were known from the Western Ghats in the family of freshwater crabs called Gecarcinucidae. So the latest discoveries bring the total species count to 41.
For indigenous communities living in and around the forests of Kerala, tadpoles of a rather puffy, purplish frog are a cherished delicacy. The practise of consuming tadpoles has been around for decades but researchers worry that harvesting them any more will soon push the endangered frog to the verge of extinction.
Found only in the Western Ghats, the Indian purple frog, Nasikabatrachus sahyadrensis, is a rather weird-looking creature known for its rather strange behaviour. It spends much of its time below ground, save the few days when it comes out to mate, after which it disappears into its burrow again. This elusive frog has tiny eyes, short limbs, a pointed nose and a large body – all adapted to a life underground.
Discovered in 2003, the purple frog was soon classified as endangered in the International Union for Conservation of Nature’s Red List due to its already declining habitat and a geographical range of less than 5,000 square km. We still don’t know a lot about the frog’s life, since much of the action happens underground, or about its dwindling numbers.
Now, a five-year survey (2008–2012) by the scientist who discovered the species has revealed that a single tribal household of four consumes an average of about 1,500 tadpoles in one monsoon season (July to September). There are 100 to 150 households in the area where the survey was conducted.
