Source region (?) | Unknown References (not structured): Edwards C (1976) A study in erratic distribution: the occurrence of the medusa Gonionemus in relation to the distribution of oysters. Advances in Marine Biology 14: 251-284. Comments: The origin of the sample is unknown. |
Pathway / Vector (?) | Unknown References (not structured): Edwards C (1976) A study in erratic distribution: the occurrence of the medusa Gonionemus in relation to the distribution of oysters. Advances in Marine Biology 14: 251-284. Comments: It is unclear as to whether it might have arrived with movements of oysters. However, there are no accounts of oysters being stored in the tanks at the Dove Marine Laboratory. |

Advances in Marine Biology 14: 251-284. Comments: Sporadically appearing on the east coast of Britain and often in aquarium or other tanks, most probably because they become more easily recognised under these circumstances. Its overall status is not clear there being no known recent records of the species. |
