Snail-pace, a paradox in speed: Infestation of the giant African snail (Achatina fulica) in peri-urban horticulture of Bengaluru

Urban Farm DB summary

A report documenting the giant African snail (Achatina fulica) in urban and terrace gardens in Bengaluru, India (12°57'N, 77°38'E, 965 MSL) over a six-month observation period, in peri-urban horticulture. Its occurrence in Bengaluru (formerly Bangalore) was first reported in 1979, more than a century after two specimens were introduced into a garden in Calcutta (Kolkata) by William Henry Benson in 1847, after which it is assumed to have spread across India and much of Asia; the paper cites the genetic closeness of current snail populations to the original Kolkata specimens as evidence for this spread.
