List of non-marine molluscs of Trinidad and Tobago
The non-marine molluscs of the republic of Trinidad and Tobago (which comprises two West Indian islands) are a part of the molluscan fauna of Trinidad and Tobago, part of the Natural history of Trinidad and Tobago.
Location of Trinidad and Tobago in the Caribbean
Starting in the 1860s, the terrestrial and freshwater molluscs of Trinidad and Tobago have been fairly well studied. Thomas Bland published the first paper mentioning terrestrial molluscs in 1861.[1] Robert John Lechmere Guppy discovered and identified many more species from 1864 onwards, and along with Edgar Albert Smith was responsible for the earliest comprehensive species lists. The list here includes all the non-marine mollusks found in Trinidad and Tobago`s ecosystem including native, introduced and invasive species alike.
