Reproductive type (?) | Sexual References: Webber HH (1977) Gastropoda: Prosobranchia. In: Reproduction of Marine Invertebrates, Vol. 4, Molluscs: gastropods and cephalopods [ed. by Giese AC, Pearse JS] London, UK: Academic Press, 1-97 Comments: As in most prosobranchs the sexes are separate. |
Developmental trait (?) | Brooding References: Webber HH (1977) Gastropoda: Prosobranchia. In: Reproduction of Marine Invertebrates, Vol. 4, Molluscs: gastropods and cephalopods [ed. by Giese AC, Pearse JS] London, UK: Academic Press, 1-97 Comments: Fertilization is internal and eggs are deposited in well-defined capsules that are formed in the oviduct before transferring into the egg capsule gland where they become visible. After leaving the oviduct, the egg capsule, which quickly hardens on contact with seawater, is generally transferred to the foot for deposition. These egg masses are then fixed to the benthic substrata such as mollusc shells and /or rocks. |

In: Reproduction of Marine Invertebrates, Vol. 4, Molluscs: gastropods and cephalopods [ed. by Giese AC, Pearse JS] London, UK: Academic Press, 1-97. Comments: In planktonotrophic veligers, the most important food sources are flagellates, diatoms, organic and inorganic particles. Young R. venosa are generalist predators and consume large numbers of barnacles, mussels, oyster spat, and oysters. Adults feed on bivalves and may be scavengers on carrion. |
Mobility / Life stage (?) |

Comments: Lerva settle on the bottom and develop into the adult. R. venosa is a subtidal species that favours compact sandy bottoms, in which it burrows almost completely with only the siphon sticking out. |
Salinity tolerance range (?) | Exact range: 7 - 32 References: Summerson, R., Darbyshire, R., & Lawrence, E. (2007). Invasive marine species range mapping. Australian Government, Bureau of Rural Sciences. The detailed coments are from: Mann & Hardimng 2003. Salinity Tolerance of Larval Rapana venosa: Implications for Dispersal and Establishment of an Invading Predatory Gastropod on the North American Atlantic Coast. Biol. Bull. 204: 96–103. Comments: Mean percentage survival of Rapana venosa veligers ranged from 2.3% at 15 d and 7 ppt to 100% at 27 d and 22 ppt (Table 1). Veliger age and salinity significantly affected the percentage survival (ANOVA, P 0.001; Table 2). There was a significant interaction between veliger age and salinity (ANOVA, P 0.001; Table 2). Veligers aged 15 and 17 d were significantly less tolerant of salinity changes than veligers of all other ages (ANOVA, P 0.001; Fisher’s test, P 0.05). Veligers older than 25 d posthatch had a significantly higher percentage survival than all other ages except 11 d and 21 d (ANOVA, P 0.001; Fisher’s test, P 0.05). Veligers aged 21 d had a significantly higher percentage survival than all younger veligers as well as those with an age of 23 d (ANOVA, P 0.001. |
Habitat modifying ability potential (?) | Keystone species References: Kerckhof F, Vink RJ, Nieweg DC, Post JJN (2006) The veined whelk Rapana venosa has reached the North Sea. Aquatic Invasions, 1(1):35-37 Comments: R. venosa is considered as one of worst invaders worldwide. It has a high ecological fitness as evidenced by its high fertility, fast growth rate and broad tolerance to salinity, temperatures, water pollution and oxygen deficiency, giving it all the characteristics of a successful invader. R. venosa is an active predator of epifaunal bivalves and its proliferation is a serious limitation to natural and cultivated populations of oysters and mussels. |
