Species | Conchoderma auritum [WoRMS] | |

Family | Lepadidae | |
Order | Lepadiformes | |
Class | Hexanauplia | |
Phylum | Arthropoda | |
Synonym (?) | ||
Sub-species level (?) | Not entered |
Native origin (?) | Not entered References (not structured): Gittings, S. R. 1985. Notes on barnacles (Cirripedia: Thoracica) from the Gulf of Mexico. Gulf and Caribbean Research, 8(1), pp. 35-41. Comments: Cosmopolitan |
Life form / Life stage (?) |
Comments: Attached to the Whale barnacle Coronula diadema and sometimes Coronula reginae. It seems to be a rule that no Coronula is without a Conchoderma. Whether this is a form of symbiosis has been discussed by Broch (1924b). |
Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual References: Tomiqka, S., Kakui, K., Kado, R., Sato, M. 2020. First record of Conchoderma auritum (Linnaeus, 1767)(Crustacea: Cirripedia: Lepadidae) from rishiri island. Comments: Species is simultaneous hermaphrodite, the rabbit-ear barnacle reaches sexual maturity at a scutum length of 7 mm. |
Developmental trait (?) | Unknown Comments: Not available. |
Characteristic feeding method / Life stage (?) |

Mobility / Life stage (?) |

Comments: Conchoderma can be considered generalists, since they occur on both living organisms and inanimate objects, such as ship hulls. It is known to settle on slowly moving marine mammals and requires hard surfaces for attachment. |
Salinity tolerance range (?) | Venice system: 6. Polymixohaline [18-30psu] 7. Euhaline [30-40psu] |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: Farrapeira, C. M. R., Melo, A. V. D. O. M. D., Barbosa, D. F., Silva, K. M. E. D. 2007. Ship hull fouling in the Port of Recife, Pernambuco. Brazilian Journal of Oceanography, 55, pp. 207-221. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Unknown Comments: Not available. |
Known human health impact? | Known Comments: Harmless. |
