The vertical distribution pattern delineated that the number of species decreased from high to low tide zone at two sites, however, marked differences were encountered with reference to the density distribution. At Sandspit, highest annual mean density was observed in the high tide zone followed by low and mid tide zones respectively, while, at Korangi the highest annual mean density was observed in the mid tide zone followed by high and low tide zones respectively. An important correlation was observed between the vertical distribution pattern of species and the sediments.

However, the key ecological the distribution of molluscs in mangrove areas, factors that actually determine the fate of e.g. the factors that governs the vertical molluscs and govern their distribution pattern in distribution of gastropods and ranged out the mangrove habitat, is still a debatable question distribution zones for each species mainly based among the ecologist. The controversy exists upon the desiccation tolerance11. The intertidal about the totality of factors affecting the zonation seems maintained by the different distribution of these intertidal individuals. responses of organisms to change in physical Most studies on intertidal gastropods and biotic factors which vary from low to high suggest that the level of desiccation tolerated by tide zones12.

Asset Saltmarsh and Samphire Description Areas of saline, mineral-rich, organic-rich, and low oxygen coastal soils within and above high tide level, often fronted by mangroves, and backed by saltbush shrubland. Saltmarsh supports various salt-tolerant plants, with samphires being the most common and significant in terms of cover in South Australia. There are distinct assemblages of salt-tolerant invertebrates associated with saltmarsh habitats. Saltmarshes provide habitat for fishes, including juveniles of species which utilise other marine habitats, and are an important feeding area for various bird species, including migratory shore birds.

Conids are well known for being active predators on worms, fishes, and even other snails. Cones are venomous gastropods, meaning that they use a sophisticated cocktail of hundreds of toxins, named conotoxins, to subdue their prey. Although this venom has been studied for decades, most of the effort has been focused on Indo-Pacific species. Thus far, Atlantic species have received little attention despite recent radiations have led to a hotspot of diversity in West Africa, with high levels of endemic species. In fact, the Atlantic Chelyconus ermineus is thought to represent an adaptation to piscivory independent from the Indo-Pacific species and is, therefore, key to understanding the basis of this diet specialization. We studied the transcriptomes of the venom gland of three individuals of C. ermineus. The venom repertoire of this species included more than 300 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity.

Biodiversity Data Journal 8: e54724. https://doi.org/10.3897/BDJ.8.e54724 Abstract Amphibolidae is one of the most abundant families of gastropods in estuarine environments of south-eastern Australia. However, the range limits of the species of Salinator, one of the family’s two genera in the region, remain unclear partly due to uncertainty of identifications based solely on shell morphology. Insufficient data have been collected to address questions regarding the genetic variability of any of the species of Salinator. Here, DNA sequences from a segment of the cytochrome c oxidase subunit I and 28S ribosomal RNA genes were collected to investigate the distribution and variation of the three Salinator species in the region, these being S. fragilis, S. rhamphidia and S. tecta. The results demonstrate a large range extension in S. rhamphidia and suggest that S. tecta may have limited distribution in Tasmania. In contrast to previously-studied estuarine Mollusca in the south-eastern coasts of the mainland and Tasmania, S. rhamphidia has regional differentiation. There is evidence of genetic disequilibrium within S.
