Axes terete to markedly flattened, especially basally, with short, more slender laterals with spinous branchlets. Optimum growth of G. tikvahiae occurs between 24°C - 30°C optimum range of 24 - 30°C. As this species is capable of forming excessive biomasses in eutrophic coastal waters, G. tikvahiae can have negative impacts within its normal distributional range (Lapointe and Bedford, 2007). Although the species is not reported as invasive it can negatively impact and even displace other indigenous species due to the formation of massive blooms (Lapointe and Bedford, 2007). 1987. The primary character used to separate G. tikvahiae from other Gracilaria species found in the lagoons and estuaries along the Atlantic coast of North America is the flattened or part flattened thallus (Thomsen et al., 2005). Wallingford, UK: CABI. In the Philippines, it is called gulaman and used to make gelatin.

The species is also reported from the Caribbean and South America (Taylor, 1960: Ganesan, 1990; Littler and Littler, 2000; Diaz-Pulido and Díaz-Ruíz, 2003) but the conspecifics of tropical populations has been questioned (Bellorin et al., 2002; Gurgel et al., 2004).
