Biological Invasions 4: 333–338 Comments: Haploid spores are equiped with special 'wing' that allows them to swim up to 5-6 hours and relocate. |
Sociability / Life stage (?) |

Reproductive frequency (?) | Iteroparous References (not structured): ICES (2007) Alien Species Alert: Undaria pinnatifida (wakame or Japanese kelp). ICES Cooperative Research Report No. 283. pp.36 |
Reproductive type (?) | Asexual Sexual References: Fang TC, Dai J, Chen D (1982) Parthenogenesis and the genetic properties of parthenosporophytes of Undaria pinnatifida. Acta Oceanologica Sinica, 1: 107–111 Comments: Sexual reporduction is typical for the species. Asexual reproduction through unfertilized eggs, which can develop into parthenogenetic sporophytes, has been recorded in laboratory experiments. |

Biological Invasions 4: 333–338 Comments: Male gamets are released into water in order to reach female gamets. |

Habitat modifying ability potential (?) | Autogenic ecosystem engineers Keystone species References: Cecere E, Petrocelli A, Saracino D (2000) Undaria pinnatifida (Fucophyceae, Laminariales) spread in the central Mediterranean: its occurrence in the Mar Piccolo of Taranto (Ionian Sea, southern Italy) Cryptogamie, Algol., 21 (3): 305-309 Comments: This species can grow up to 3m long and due to its big size it can have various effects on local communities - both +ve and -ve. it can provde food & shelter to some species but at the same time can limit the light siginificantly to species living below it and push local species out of the ecosystem. |
