Sub-species level (?) | Not entered |
Native origin (?) | Ocean: Indian --> Ocean region: E Indian Ocean Ocean: Pacific --> Ocean region: C Tropical Pacific --> Ocean region: E Tropical Pacific --> Ocean region: NE Pacific --> Ocean region: SE Pacific --> Ocean region: SW Pacific --> Ocean region: W Tropical Pacific References (not structured): Zullo VA (1992) Balanus trigonus Darwin (Cirripedia, Balaninae) in the Atlantic basin: an introduced species? Bulletin of Marine Science 50: 66-74 Comments: Darwin has specimens from Java, East Indies, Australia, New Zealand, Peru, Colombia, California |
Life form / Life stage (?) |
References (not structured): Werner Jr, W. E. 1967. The distribution and ecology of the barnacle Balanus trigonus. Bulletin of Marine Science, 17(1), pp. 64-84. |
Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Self-fertilization Sexual |
Developmental trait (?) | Brooding Planktotrophy References: Werner Jr, W. E. 1967. The distribution and ecology of the barnacle Balanus trigonus. Bulletin of Marine Science, 17(1), pp. 64-84. Comments: The fertilised eggs are brooded within the shell of the receiver adult until they develop into a nauplius larvae. A single adult barnacle may release over 10,000 larvae. Naupli are then released into the water as plankton. |

|
Mobility / Life stage (?) |
|
Salinity tolerance range (?) | Exact range: 22 - 40 References: Thiyagarajan, V., Harder, T., Qian, P. Y. 2003. Combined effects of temperature and salinity on larval development and attachment of the subtidal barnacle Balanus trigonus Darwin. Journal of Experimental Marine Biology and Ecology, 287(2), pp. 223-236. Comments: Balanus trigonus prefers saline (26-40 ppt), subtidal habitats in warm-temperate, subtropical and tropical seas. |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: Werner Jr, W. E. 1967. The distribution and ecology of the barnacle Balanus trigonus. Bulletin of Marine Science, 17(1), pp. 64-84. Comments: B. trigonus grows on a wide range of hard surfaces, including mangroves, rocks, oysters, crabs, pilings, docks and ship hulls. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Wang, W. X., Rainbow, P. S. 2000. Dietary uptake of Cd, Cr, and Zn by the barnacle Balanus trigonus: influence of diet composition. Marine Ecology Progress Series, 204, pp. 159-168. Comments: Concentrations of several metals (e.g., Cu and Zn) in barnacles are probably the highest recorded among any marine animals. |
Known human health impact? | Known Comments: Harmless. |
Known economic impact? | Known References: Smithsonian Environmental Research Center. (n.d.). Balanus trigonus. Retrieved from: (https://invasions.si.edu/nemesis/species_summary/89628) Comments: It is common in subtropical waters, frequently reported from ship hulls, and contributes to barnacle fouling of ships and harbor structures. |
Known measurable environmental impact? | Known References: Smithsonian Environmental Research Center. (n.d.). Balanus trigonus. Retrieved from: (https://invasions.si.edu/nemesis/species_summary/89628) Comments: B. trigonus is a potential competitor with other fouling organisms in suitable habitats. |
