Movement: Vessels. Rapana Whelk This NPC can be found in Dread Wastes (7), Azsuna (3), and Stormheim (2). Pet Battle: Dread Wastes Has been spotted fighting other whelks for prime food sources. The veined rapa whelk is a non-indigenous species that have been introduced into the U.S. 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. These whelks were introduced into the Chesapeake Bay and may cause damage to native species. Since they were discovered in 1999 by the VIMS Trawl Survey Group, numerous reports have been documented in the lower James, Elizabeth, and York Rivers, Mobjack Bay, and lower Chesapeake Bay. One rapa whelk was collected at Tangier Island, the northernmost finding in the Bay. What's the harm? Rapa whelk feed on oysters, clams, and mussels.

First report of predation by a small shark on the invasive rapa whelk Rapana venosa (Valenciennes, 1846) in Argentinean waters. BioInvasions Record, 5(3) 

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. The relationships between rapa whelk female size and the fecundity (number of developing eggs, embryos and larvae) per egg capsule showed that fecundity increased with the female size. Of three different areas, the fecundities of female rapa whelk at the S-1 area (the highest salinity area) were the highest, and those in S-3 area were the lowest.

Rapana venosa (Veined Rapa Whelk) is native to the Northeast Pacific, from the southern Pacific coast of Russia, to the Sea of Japan, Yellow Sea, and East China Sea (Golikov et al. 1976; Mann and Harding 2000). In 1947, it was first collected from the Black Sea, in Novorossiyski Bay, where it was probably transported by ships, or with Crassostrea gigas (Pacific Oysters). 2015-02-25 Veined rapa whelk - Photo by Juliana M.

No known hybrids or varieties of R. venosa exist in the literature. In the United States, whelk refers to several large edible species in the genera Busycon and Busycotypus, which are now classified in the family Buccinidae. These are sometimes called Busycon whelks.

The veined rapa whelk (Rapana venosa) is an economically important sea snail in China, and since 1992, there has been interest in its commercial aquaculture [1]. However, sea-ranching efforts have been hampered by difficulties cultivating larvae during the settlement and metamorphosis stages.

Other names, ›Purpura venosa ›Rapana venosa (Valenciennes, 1846).

The Rapana Whelk is available as an S/S, an H/B, and a B/B. Per the choice for Rusty Snail breed, among these last two snails, the H/B is the strongest. The Silkbead Snail is only available as an H/S and a B/B. Ignoring the speed, the health & health vs health & attack power is close. I'd favor the B/B, but not greatly so.
