While the seven classes within the phylum Mollusca are clearly defined morphologically and molecularly, relationships between them have long been contentious. Two recent phylogenomic studies take an important step forward with intriguing implications for their evolution.

The purpose of this paper is to describe the main characteristics of macroinvertebrate species in response to environmental forcing factors. Overall, 23 species of Mollusca, 4 species of Arthropods, 3 species of Echinodermata and 3 species of Annelida were identified at the 9 sampling stations during four sampling periods. Individual species of Mollusca constituted 36.4% of the total abundance,...

Molluscs, comprising one of the most successful phyla, lack clear evidence of adaptive immunity and yet thrive in the oceans, which are rich in viruses. There are thought to be nearly 120,000 species of Mollusca, most living in marine habitats. Despite the extraordinary abundance of viruses in oceans, molluscs often have very long life spans (10 to 100 years). Thus, their innate immunity must b...

This dataset records the occurrence and inventory of molluscan fauna on Gueishan Island, the only active volcanic island in Taiwan, based on the literature survey and field investigation conducted between 2011 and 2012. The literature review involved seven studies published from 1934 to 2003, which collectively reported 112 species from 61 genera and 37 families of Mollusca on Gueishan Island. ...

Molluscum contagiosum is a common viral skin infection in children with atopic diathesis and not rare in HIV patients. We report a 45-year-old psoriasis patient who developed eruptive mollusca contagiosa during an antipsoriatic treatment with efalizumab.

Abstract One of nature’s most valuable resources, biodiversity plays a critical role in meeting many human requirements and protecting from environmental extremism conditions. Mollusca benthic invertebrates are important biota aquatic ecosystems need further investigation. The current study highlights some species recorded Al-Delmage Marsh Iraq. points out six Mollusca. These Melanoides tubercu...

Benthic fauna caught by ring dredge and 2 m beam trawl at the NATURA 2000 Sylt Outer Reef (SAR) Borkum Ground (BRG) sites in North Sea are examined relation to intensity of mobile bottom-trawling fisheries. Samples were taken from 33 stations two areas, collected benthic fauna, consisting infauna, epifauna, demersal fish was determined. A total 123 species found, phyla Chordata, Mollusca, Arthr...

The present study aimed at the community of macrobenthic invertebrates in three stations Shatt Al-Arab River, including Al-Muftia, Sendibad, and Al-Mohammadiat, samples were collected for a period six months, from July 2018 to December 2018, during which some environmental factors measured. invertebrate monthly replicates each station isolated identified, densities, relative abundance, ecologic...

The 18S rRNA sequences of 12 molluscs, representing the extant classes Gastropoda, Bivalvia, Polyplacophora, Scaphopoda, and Caudofoveata, were determined and compared with selected known 18S rRNA sequences of Metazoa, including other Mollusca. These data do not provide support for a close relationship between Platyhelminthes (Turbellaria) and Mollusca, but rather suggest that the latter group ...
