''Hammerhead worms,'' or ''Broadhead planarians'' (genus Bipalium), are large predatory, carnivorous, and even cannibalistic land planarians. Some species prey on earthworms, while others may also feed on mollusks. They are called hammerhead worms due to the distinctive shape of their head region. Land planarians are unique in possessing a ''creeping sole,'' a highly ciliated region on the ventral epidermis that aids in their movement over substrates. Native to Asia, several species have become invasive in the United States, Canada, and Europe. Some studies have begun investigating the evolutionary ecology of these invasive planarians. Reproduction in Bipalium can be either asexual or sexual, and all species are hermaphroditic. A hammerhead worm was observed in Tehatta, West Bengal, India, on August 28, 2024, displaying its characteristic slender or elongated body, moving in a snake-like fashion with its head bobbing from side to side.

The little ringed plover (Charadrius dubius) measuring 15 to 18 cm in length and weighing 25 to 50 grams belongs to the family of lapwings and plovers, the Charadriidae distributed in Europe, central Asia, Middle East, central Africa, Indian subcontinent and southeast Asia. These plover species have a distinctive bright yellow eye-ring. These plovers are polytypic species. Breeds on stony substrates around lakes, gravel pits, and along rivers; migrants occur in a wide variety of fresh and brackish wetland habitats, but rarely out on open tidal areas. The call sounds like ''peu''. This photo was taken at the bank of Hooghly River (Ganges River distributary) in Rudrapara, Mayapur, West Bengal, India, on 29/01/2023.
