Sub-species level (?) | Not known |
Native origin (?) | Ocean: Indian Ocean: Pacific References (not structured): Galil BS (2006) Caulerpa taxifolia: Delivering Alien Invasive Species Inventories for Europe Comments: Caribbean coasts, Gulf of Guinea, Red Sea, East African coast, Maldives, Seychelles, northern Indian Ocean coasts, southern China Sea, Japan, Hawaii, Fiji, New Caledonia and tropical/sub-tropical Australia. |
Life form / Life stage (?) |
References (not structured): Galil BS (2006) Caulerpa taxifolia: Delivering Alien Invasive Species Inventories for Europe Meinesz A (2002) Introduction for the International Caulerpa taxifolia Conference.International Caulerpa taxifolia Conference Proceedings Comments: Most of the Caulerpa species, such as native C. taxifolia, are monoecious.The thallus dies after release of gametes (holocarpy). After the fusion of the gametes, the zygote produces an intermediate stage called the protosphaera before becoming an adult plant. It also reproduces vegetatively via fragmentation. During summer (June to September) the thallus of the aquarium strain attains extreme growth rates of up to 32mm of new stolon per day and a new frond every other day (month of August), resulting in frond densities of approximately 5000 fronds/m2 |
Sociability / Life stage (?) |
References (not structured): Meinesz A (2002) Introduction for the International Caulerpa taxifolia Conference.International Caulerpa taxifolia Conference Proceedings Comments: In the Mediterranean Sea, C. taxifolia forms large, dense colonies that are competitively dominant, in contrast to tropical seas, where such colonies never develop. |
Reproductive frequency (?) | Iteroparous References (not structured): Galil BS (2006) Caulerpa taxifolia: Delivering Alien Invasive Species Inventories for Europe Comments: Sexual reproduction remains unknown in aquarium strains, because only male gametes are formed. It also reproduces vegetatively via fragmentation. During summer (June to September) the thallus of the aquarium strain attains extreme growth rates of up to 32mm of new stolon per day and a new frond every other day (month of August), resulting in frond densities of approximately 5000 fronds/m2. |
Reproductive type (?) | Asexual Self-fertilization Sexual References: Galil BS (2006) Caulerpa taxifolia: Delivering Alien Invasive Species Inventories for Europe Meinesz A (2002) Introduction for the International Caulerpa taxifolia Conference.International Caulerpa taxifolia Conference Proceedings.

Toxicity / Life stage (?) | Not relevant References: Ferrer E, Garreta AG, Ribera MA (1997) Effect of Caulerpa taxifolia on the productivity of two Mediterranean macrophytes. Mar. Ecol. Prog. Ser. 149: 279-287 Comments: Caulerpenyne is a main secondary metabolite of Caulerpa taxifolia; it is an acetylenic sesquiterpene, which is specific to Caulerpa. It has recently been shown that the Mediterranean populations of C. taxifolia synthesize not only caulerpenyne, present in all species of Caulerpa, but also other potentially toxic terpenes, described in these plants for the first time: Taxifolial A, Taxifolial B , Taxifolial C, 10, 11 epoxycaulerpenyne and the monoterpene Taxifolial D. Some of these compounds could be products of degradation or a precursor of caulerpenyne. Several authors have demonstrated that the toxic compounds of Caulerpa taxifolia could be released into the surrounding water. |

Association with vessel vectors (?) | Ballast waters References: Da Silva, E. V., De Moura, C. A., Xavier, R. D. C. Relationship among Ballast Water, Bioincrustration and Invasion of Exotic Species. Comments: C. taxifolia we consider that may have been introduced recently in our coast, possibly by an anthropogenic process through ballast water or bioincrustration. |
