Reproductive type (?) | Sexual References: Hargis, W. J. , MacKenzie, C. L. 1961. Sexual Behavior of the Oyster Drills: Eupleura caudata and Urosalpinx cinerea. Nautilus, 75(1). Comments: U. cinerea, the Atlantic Oyster Drill, has separate sexes. It reaches maturity at about 15 months to 3 years. Fertilization is internal. |
Developmental trait (?) | Brooding Direct development References: Hargis, W. J. , MacKenzie, C. L. 1961. Sexual Behavior of the Oyster Drills: Eupleura caudata and Urosalpinx cinerea. Nautilus, 75(1). Comments: Eggs are laid on rocks or shells in vase-shaped egg capsules, which contain 10-13 eggs. The number of capsules per spawning ranged from 4 to 271, but 25-100 appears to be a more normal range. The eggs hatch in about 22-78 days, into miniature snails, 1.0-1.5 mm long. Development is direct, so dispersal is limited. |
Characteristic feeding method / Life stage (?) |
References (not structured): Hanks, J. E. 1957. The rate of feeding of the common oyster drill, Urosalpinx cinerea (Say), at controlled water temperatures. The Biological Bulletin, 112(3), pp. 330-335. Comments: Urosalpinx cinerea feeds on barnacles, mussels, oysters, and other bivalves, including oysters and mussels. The drill rasps a circular hole in the prey shell and digests its contents. The size of the prey selected tends to be roughly equal with the shell length of the gastropod. |
Mobility / Life stage (?) |
|
Salinity tolerance range (?) | Venice system: 5. α-Mesohaline [10-18psu] 6. Polymixohaline [18-30psu] 7. Euhaline [30-40psu] References: Manzi, J. J. 1970. Combined effects of salinity and temperature on the feeding, reproductive, and survival rates of Eupleura caudata (Say) and Urosalpinx cinerea (Say)(Prosobranchia: Muricidae). The Biological Bulletin, 138(1), pp. 35-46. Comments: They tolerate salinities as low as 15 PSU, but need at least 20 PSU for successful egg development. |
Habitat modifying ability potential (?) | Unknown Comments: Not available. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Unknown Comments: Not available. |
Known human health impact? | Known Comments: Harmless. |
Known economic impact? | Known Comments: Urosalpinx cinerea is regarded as a serious pest to oyster culture and fisheries in its native East Coast waters, and in many of the bays to which it has been introduced. |
Known measurable environmental impact? | Known References: Gibbs, P. E., Spencer, B. E., Pascoe, P. L. 1991. The American oyster drill, Urosalpinx cinerea (Gastropoda): evidence of decline in an imposex-affected population (R. Blackwater, Essex). Journal of the Marine Biological Association of the United Kingdom, 71(4), pp. 827-838. Comments: Urosalpinx cinerea is a potential competitor with native predatory snails. Aside from their commercial value, oyster beds are important as habitat and a food source for fishes and invertebrates, and for maintenance of water quality through filtration of the water column. |
