New Guinea Flat Worms: The Giant Hammerheads of the Tropical World

Deep within the tropical greenhouses of Kew Gardens in London lies a fascinating story about a peculiar creature, the new Guinea flat worm, also known as Bipalium kewense. Its origin is shrouded in mystery, and it wasn't until much later that scientists discovered its true roots lay in Vietnam. The name 'Kewense' is derived from the Latin term meaning 'from Kew,' reflecting its first recorded sighting in 1878.

Measuring an impressive 30 centimeters in length - equivalent to a shoe size larger than 44 - this giant hammerhead worm is truly a sight to behold. Its unusual appearance has captivated scientists and naturalists alike, leading to numerous reports of new species discovered in the Antilles and beyond.

The West Indies, with its tropical climate, provides an ideal habitat for species that would struggle to survive on mainland France. In recent years, over 10 species of land flatworms have been reported in metropolitan France alone, including a giant species reaching lengths of up to 30 centimeters and another found in more than 70% of the country's departments.

An unexpected development came when photographs of these unusual creatures began flooding in from overseas French departments, particularly the West Indies. In response, a citizen science survey was launched in France to learn more about these intriguing flatworms. The initiative proved fruitful, as an inhabitant of Cagnes-sur-Mer, France, discovered a land flatworm in his garden and promptly sent photographs to a network of naturalists.

According to a report by Jean-Lou Justine and Hugh Jones for Phys Org., this citizen science project has shed new light on the distribution and habits of these remarkable creatures. The discovery of new Guinea flat worms in various parts of France highlights the importance of continued research into these fascinating species, ensuring that their habitats are protected and preserved for future generations to study and marvel at.
