The family Strombidae has undergone an extensive taxonomic revision recently[6] and many subgenera, including Eustrombus, were elevated to genus level by some authors.

Simone proposed a cladogram (a tree of descent) based on an extensive morpho-anatomical analysis of representatives of Aporrhaidae, Strombidae, Xenophoridae and Struthiolariidae, which included T.

[7] Titanostrombus goliath is found along the northeastern and southeastern coast of Brazil, including several Brazilian states, such as Ceará, Rio Grande do Norte, Pernambuco, Alagoas, Bahia and Espírito Santo and insular regions, such as Abrolhos Marine National Park.

[2] Since October 2008, a small population of both juvenile and adult specimens of Titanostrombus goliath was reported by fishermen to have been established in at least two locations along the west coast of Barbados.

Oxenford also assessed that the species was not invasive and unlikely to pose a threat to native marine flora and fauna, but opined that overfishing could cause severe depletion of its numbers.

This is because the shell is a popular decorative object which is widely utilized in handicrafts and commonly sold as a souvenir in local markets and craft stores in several regions of Brazil.
