Developmental trait (?) | Brooding References: Collado, G. A., Chihuailaf, E., Muñoz-Herrera, N., Contreras, M., Novoa, F., Valladares, M. A. 2021. Reproductive aspects of the poorly known and critically endangered freshwater snail Heleobia atacamensis (Gastropoda: Truncatelloidea). PeerJ, 9, e11550. Comments: H. charruana has indirect development. Species attaches single egg capsules to living shells and opercula of conspecifics from which a free-swimming veliger larva hatches 5 days post-oviposition. The veliger has a simple bilobed velum, suggesting a short pelagic larval life. In H. charruana, free-swimming larvae hatch 10 days post-oviposition, remaining among the aquatic plants by which they can be dispersed by rafting. |

Comments: H. charruana lives among the roots of floating aquatic macrophytes (Eichhornia and Salvinia). |
Salinity tolerance range (?) | Exact range: 1.5 - 34.5 References: van Haaren, T., Worsfold, T. M., Stelbrink, B., Collado, G. A., Gonçalves, I. C., Serra, W. S., ... Gittenberger, E. 2021. Heleobia charruana (Gastropoda, Truncatelloidea, Cochliopidae), a South American brackish water snail in northwest European estuaries. Basteria, 85(1), pp. 82-91. Comments: Th e species may occur at a variety of salinities and the animals can survive considerable changes in salinity during their lifespan. Variations in salinity from 34.5 to 4.5‰ or even 1.5‰ within 10 hours at a single site, related to tides and winds. |

Association with vessel vectors (?) | Unknown References: van Haaren, T., Worsfold, T. M., Stelbrink, B., Collado, G. A., Gonçalves, I. C., Serra, W. S., ... Gittenberger, E. 2021.

Comments: The means of introduction of H. charruana to Europe are also unknown, but shipping would be the most obvious possibility. More likely, they were present somewhere inside a vessel in the sediment of a ballast water tank, a sea chest and/or another sheltered niche area. |
