In Trinidad and Tobago annelids are found in virtually all habitats. Earthworms are obviously found in soil and include some large species such as the Megascolex sp. which can be seen or heard in higher areas such as El Tucuche, these worms apparently make a slurping sound as they retreat down their burrows when people approach. In the seas there are many species of annelids in the mudflats, coral reefs and sandy areas. Leeches can be found in freshwater habitats as well as the rainforests.

The collections are quite small with only a few specimens in spirit. There are a few earthworms and leeches but most of the specimens are marine polychaetes including the large fireworms commonly found on coral reefs.
