Comments: eggs are incapsulated in a egg capsule attached to the substratum. No studies are available on the larvae of this species. However, the congeneric Ergalatax contracta has non-dispersive larvae, crawling juveniles hatching from the egg mass |

Association with vessel vectors (?) | Unknown References: Zenetos, A., & Ovalis, P. (2008). Eastward spread of Ergalatax junionae Houart, 2008 (Gastropoda, Mollusca), a recent alien species in the Mediterranean. Journal of biological research-Thessaloniki, 10, 221-223. Comments: VESSEL TRANSPORT, PROBABLY AS BIOFOULING (other species of the genus Ergalatax don't have a planktonic larva) IS CONSIDEREDFOR THE MOST LIKELY VECTOR FOR THIS SPECIES, BUT THERE IS NO DIRECT EVIDENCE. Based on first identification and presumed origin, natural expansion of their Red Sea populations into the Mediterranean following the common route of Lessepsian immigrants was assumed. However, on tracing the history of E. junionae introduction into the Mediterranean and given its origin, it is suspected that shipping is the most probable vector instead. Indeed, the ships docking at oil terminals in the Gulf of Iskederun (Eastern Turkey) could have introduced the species into the Eastern Mediterranean Sea. |
