It can prey heavily on native shellfish and aquaculture species. Researchers at the Smithsonian identified the creature as a veined rapa whelk (Rapana venosa), a species native to Asia. They were likely introduced to the Chesapeake Bay through ballast water from ships. The outside of the shell is usually grey to red/brown.

DAISIE European Invasive Alien Species Gateway. Veined rapa whelks are native to Asia. Movement: Vessels. The native habitat of these whelks includes waters in the western Pacific Ocean including the Sea of Japan, Yellow Sea, East China Sea, and the Bohai Sea. For this reason, it is not uncommon for high concentrations of such compounds to be present in the sea water near shipyards and docking areas, consequently exposing the nearby marine life to its possibly harmful effects. To clarify the source and invasive routes of a successful world-wide invader, the veined rapa whelk, Rapana venosa, genetic variability of samples from five representative native populations from coasts of Japan and China and 13 worldwide invasive populations was analyzed using 11 nuclear microsatellite loci. Map showing the known global distribution of reproducing rapa whelk populations including the native range in Korean, Japanese, and Chinese waters (A.) Fleeing cold waters in the winter, this species may migrate to warmer, deeper waters, thereby evading cool surface waters. A dramatic decrease of genetic variation was detected in the invasive populations compared with the native … These are sometimes called Busycon whelks. Non-native populations in the order of introduction and/or discovery are the Black Sea and Mediterranean region (B. The World Register of Introduced Marine Species estimates that globally there are 1,711 introduced marine species (WRiMS, 2019), but not all of these are – or will go on to become – invasive in their new locations. Veined Rapa Whelk or Asian Rapa Whelk: Class: Gastropoda: Family: Muricidae: Genus: Rapana: Impacts: Feeding on native mussels, oysters and other molluscs, veined whelk reduced mussel and oyster stocks, thereby causing a decline in the fish stocks that feed on them. From 1959 to 1972, its range extended into the northwest Black Sea, to the coastlines of Romania, Bulgaria and Turkey. Please keep the snail alive in seawater. Rapana venosa, common name the veined rapa whelk or Asian rapa whelk, is a species of large predatory sea snail, a marine gastropod mollusk or whelk, in the family Muricidae, the rock shells.

Veined Rapa Whelk Native to the Pacific Ocean, ballast water brought it to Chesapeake Bay. The single­ shelled mollusk, \iisually similar to the native whelks (Busycon carica, B. sinistrum, Busycotyjnts canaliwlatus, Rapana venosa, the Veined Rapa Whelk, is a large gastropod mollusc native to Northern Asia (Figure 1). The native range of R. venosa includes the Yellow Sea, Bohai Sea, and Sea of Japan (Figure 2). The whelk can also secrete a thick mucus that may or may not contain biotoxins to weaken the prey.
