A molluscan class struggle: exploring the surprisingly uneven distribution of chemosymbiosis among two major mollusk groups

open access: yesFrontiers in Marine Science, 2023
Many bivalves and gastropods from marine reducing environments such as deep ocean hydrothermal vents and seeps host chemosynthetic bacteria in a nutritional symbiosis. Despite their functional similarities, the distribution of chemosymbiosis in these two

Accumulation of bacteriophage T4 by bivalves Unio pictorum and Anodonta cygnea in model experiments [PDF]

open access: yesE3S Web of Conferences
Bivalve mollusks are filter feeders that accumulate various particles suspended in water, including viruses. Shellfish also accumulate bacteriophages, but, unfortunately, there is little information about this, despite the fact that these organisms make ...

Evolution and diversity of alpha-carbonic anhydrases in the mantle of the Mediterranean mussel (Mytilus galloprovincialis) [PDF]

open access: yes, 2019
The α-carbonic anhydrases (α-CAs) are a large and ancient group of metazoan-specific enzymes. They generate bicarbonate from metabolic carbon dioxide and through calcium carbonate crystal formation play a key role in the regulation of mineralized ...

Optimal designs of mollusk shells from bivalves to snails [PDF]

open access: yesScientific Reports, 2017
AbstractBivalve, ammonite and snail shells are described by a small number of geometrical parameters. Raup noted that the vast majority of theoretically possible shell forms do not occur in nature. The constraint factors that regulate the biased distribution of natural form have long since been an open problem in evolution.
