“…Besides, H. trunculus is believed to be an opportunistic predator that may also scavenge, that thrives in ultraoligotrophic marine waters off the coast of Israel, where food is limited (Peharda & Morton 2006) and in aquarium can survive up to months without feeding (Sawyer et al 2009). Thus, a longer experiment might be more suitable to investigate feeding traits of species like this one.…”

Sepia officinalis embryos develop inside ink-stained black encapsulated eggs fixed to the seafloor in shallow water habitats. The enveloping layers of these eggs allow the embryo to develop within a micro-environment and are thought to provide protection.Since embryological development may last months, this short-lived species spends a relatively long period of its lifespan on shallow waters, vulnerable to predation and physical stress. Yet, only a handful of species are known to feed on S. officinalis eggs, most of them fish. Marine benthic invertebrates, however, are likely candidates contributing to predation of this critical life stage. In this study, several invertebrate marine species, from 6 different phyla and with diverse feeding habits, were investigated as potential predators of S. officinalis eggs under laboratory conditions.Feeding experiments also tested to what extent the egg capsule and lower levels of mechanical protection could deter predation and Multivariate Correspondence Analyses were performed to explore which feeding traits of the tested invertebrate species would explain the experimental results. Results showed predation on eggs by crabs and echinoderms equipped with certain prey capture methods that allowed them to feed on eggs. Also, the egg capsule appeared to provide protection from predation by certain species with less powerful prey capture tools. Prey capture tools of the tested species appeared to be the feeding trait that better explained the experimental results. Therefore, whether or not eggs were eaten in these experiments might be determined by a mechanical factor. Nonetheless this may not be the case for species that might not have fed on eggs due probably to a chemosensory question, not recognising them as food.This work thus contributes to the understanding of the ecology of early life stages of cuttlefish and the factors that can affect offspring survival and subsequently impact recruitment to the adult populations of this exploited species.iii ACKNOWLEDGMENTS This work might not have been possible without the support and help of many people.Many thanks to my directors, Fernando Fernández-Álvarez and Dr. Roger Villanueva, who taught me with patience and trusted me to embark on this study, while making the work truly feel like a journey of curiosity. Without their continuous guidance and encouragement this work would not have been the same.

“…Hexaplex trunculus (Linnaeus, 1758) is one of the most widespread and common members of family Muricidae in Mediterranean region (Rilov, Benayahu, & Gasith 2004;Morton, Peharda, & Harperet, 2007); H. trunculus is a generalist opportunistic predator, can forage on a wide variety of prey (Morton et al, 2007) and is a heavy consumer of valuable and cultivated bivalve species like Ostrea edulis and Mytilus galloprovincialis (Peharda &Morton, 2006). Moreover H. trunculus is a commercial marine food and the primary source of the ancient dye Tyrian purple (Cooksey, 2001;Lahbib, Abidli, & Trigui El Menif, 2011;Zarai, Balti, Mejdoub, Gargouri, & Sayari, 2012).…”

“…Due to its ecological importance as a generalist predator species, its impact on cultivated bivalves and its economic importance, many aspects related to H. trunculus were previously studied, for example: reproduction and larval development (Lahbib et al, 2011;Güler & Lök, 2014), aquaculture and stock management (González-Tizón, Fernández-Moreno, Vasconcelos, & Martínez-Lage, 2008;Lahbib, Abidli, & Trigui El Menif, 2010), morphology and population dynamics (Marzouk, Chenuil, Blel, & Saïd, 2016;Vasconcelos, Barroso, & Gasparet, 2016;Elhasni et al, 2017), food processing (Zarai et al, 2012), bioaccumulation and imposex (Anastasiou, Chatzinikolaou, Mandalakis, & Arvanitidis, 2016;Lahbib, Mleiki, & Trigui El Menifet, 2016;Cacciatore et al, 2018), Tyrian purple dye (Vasileiadou, Karapanagiotis, & Zotouet, 2016), as well as behavioral feeding mechanism (Rilov et al, 2004;Peharda & Morton, 2006;Morton et al, 2007;Sawyer, Zuschin, Riedel, & Stachowitsch, 2009;Güler & Lök, 2016). H. trunculus mostly accesses its preys flesh by drilling and/or chipping and can consume a broad size range of its bivalve prey; leaving abandoned shells after a few predation steps (Peharda & Morton, 2006).…”

The behavior of a group of predators may have effects which cannot be predicted using data from a solitarily observed predator however in many experimental studies on the aspects of predation, one predator at a time have been examined. In the present study consumption rates of H. trunculus were tested with experimental setups that allow communal feeding, and some reassessments were attempted to be made on the foraging capabilities of this species, which can be used in ecology and aquaculture studies alike. Furthermore, the influence of predator hunger level was evaluated in an auxiliary experiment. Experiments were designed as two equal periods. The prey species Mytilus galloprovincialis were offered to the snails in four size groups. Consumption rates of H. trunculus were found to be highly consistent between the first and the second period and were about 0.09 mussel snail -1 day -1 ; higher than previous reports. In the hunger level experiment which had a shorter experimental duration, consumption rates were quite high in the beginning and were decreased drastically after the first period as expected. Consumed prey sizes did not differ between main and hunger level experiments; therefore, snails did not make a particular size selection caused by their hunger level.

“…It inhabits both hard and soft substrates, from rocky shores to sandy-muddy. H. trunculus is regularly or occasionally fished for human consumption in several countries in the Mediterranean Sea (Poppe and Goto 1991;Houart 2001), namely in Italy, Cyprus, Turkey (Gaillard 1987), Croatia (Peharda and Morton 2006) and Tunisia (Gharsallah et al, 2004). Its commercial value is relatively low in the southern Mediterranean costs (e.g., Tunisia 1-1.5€/kg; Lahbib et al, 2010) compared to some European countries (e.g., Portugal 10-15€/kg; Vasconcelos et al, 2004).…”

Morphological studies of species with wide distribution range and high commercial value, such as the banded murex Hexaplex trunculus (Linnaeus, 1758), provide information on stock structure, which is the basis for understanding fish population dynamics and enable resource assessment for fisheries management. In the present study, we examined morphological variation among Atlantic and Mediterranean populations of H. trunculus using multivariate analysis. Our results supported the existence of four distinguishable stocks (Atlantic, Alboran, Western Mediterranean and Eastern Mediterranean), correctly classified 71.7% of specimens, and indicated significant degrees of variation in morphometric characteristics between regions. Examination of the contribution of each morphometric variable to the principal components and canonical functions indicated that differences among samples seemed to be associated with the shell and aperture length and width. Samples from the Atlantic Ocean and the Alboran Sea had the largest shell size and the greatest morphometric divergence. This strong morphometric differentiation appears to be associated with local environmental factors (exposure on the rocky shores, food availability and predation) and oceanographic current barriers.
