Nomenclatural notes
This species has been introduced into the Mediterranean (Verlaque et al. 2015: 261), apparently by aquarium trade activity and shipping, being first found in the Gulf of Iskenderum, Turkey in 2006. It is now found in Cyprus, Turkey, and Sicily. - (6 Nov 2015) - M.D. Guiry

Taxonomic notes
Cormaci, Furnari & Alongi (2014: 236) reamark: "According to Famà et al. (2002), the phylogeny based on tufA sequences shows that "... C. distichophylla is a sister taxon of C. taxifolia suggesting that they may represent morphotypes of a single species". However, Jongma et al. (2013) considering: i. the unequivocal and stable morphological differences between Caulerpa distichophylla and C. taxifolia (i.e., a slender thallus with frequent short rhizoidal pillars vs. a large thallus with spaced long rhizoidal pillars); ii. no overlapping between diagnostic characters, iii. the absence of intermediate forms, iv. the stable single nucleotide polymorphism in the tuf A region and v. the absence of C. taxifolia in the major part of its native region (southern sector of Western Australia)...", concluded that C. distichophylla Sonder is distinct at varietal level from C. taxifolia." - (15 Jul 2015) - M.D. Guiry
