Turkish Journal of Fisheries and Aquatic Sciences, 19(5), pp. 391-398. Comments: This species is a group of opportunist predatory snails that are known to attack their prey in groups. What is peculiar about this specific species is that they show no preference for the size of their prey, regardless of their hunger levels. |

Known human health impact? | Known References: Zarai, Z., Frikha, F., Balti, R., Miled, N., Gargouri, Y., Mejdoub, H. 2011. Nutrient composition of the marine snail (Hexaplex trunculus) from the Tunisian Mediterranean coasts. Journal of the Science of Food and Agriculture, 91(7), ppp. 1265-1270. Comments: Harmless. Marine snail (Hexaplex trunculus) presents increasing nutritional, commercial and economical importance, being widely consumed in northern Africa, particularly in Mediterranean countries. |
Known economic impact? | Known References: Güler, M., Lök, A. 2018. Foraging behaviors of a predatory snail (Hexaplex trunculus) in group-attacking. Turkish Journal of Fisheries and Aquatic Sciences, 19(5), pp. 391-398. Comments: H. trunculus is a commercial marine food and the primary source of the ancient dye Tyrian purple. |
Known measurable environmental impact? | Known References: Güler, M., Lök, A. 2018. Foraging behaviors of a predatory snail (Hexaplex trunculus) in group-attacking. Turkish Journal of Fisheries and Aquatic Sciences, 19(5), pp. 391-398. Comments: Muricid gastropods may have a strong effect on the population dynamics of benthic communities; the impact of their predation may cause major changes on diversity and abundance of their prey. |
