A new stygobiotic atyid shrimp from the genus Xiphocaridinella Sadowsky, 1930 (Crustacea: Decapoda: Atyidae) is described based on morphology and DNA analysis from an underground lake inside the Motena Cave (Martvili Municipality, Samegrelo-Zemo Svaneti, Western Georgia, Caucasus). The new species is genetically well isolated from the West Georgian relatives and clearly differs from the other Caucasian congeners by specific lanceolate unarmed rostrum, turned forward, and by long fingers of pereiopod I and II in both males and females.

Neotropical regions near the equator are recognized as speciation "hot spots" reflecting their abundant biodiversity. In western South America, the coasts of Panama, Colombia, Ecuador, the Galápagos Archipelago, and northern Peru form the Tropical Eastern Pacific biome. This area has the greatest heterogeneity of sympatric fiddler crab species of any portion of the planet.

Global warming has threatened all-rounded hierarchical biosphere by reconstructing eco-structure and bringing biodiversity variations. Pacific white shrimp, a successful model of worldwide utilizing marine ectothermic resources, is facing huge losses due to multiple diseases relevant to intestinal microbiota (IM) dysbiosis during temperature fluctuation. However, how warming mediates shrimp health remains poorly understood.

is the specific pathogen for "milky disease" in the Chinese mitten crab (), accounting for huge losses to the industry. And yet, there is no precise study describing the pathogenesis of , largely hindering the development of novel control methods against its causing diseases. Here, we compared the transcriptomes of cells collected from a control group (cultured without hemocytes) and a treatment group (cultured with hemocytes), using RNA sequencing.

The Pacific white shrimp () is economically significant, and its growth is regulated by multiple factors. Carboxypeptidase B (CPB) is related to protein digestion, but its gene sequence and features in are not fully understood. This study aimed to explore the molecular and functional properties of CPB in .

Microorganisms, including bacteria, fungi, and protists, are key drivers in aquatic ecosystems, maintaining ecological balance and normal material circulation, playing vital roles in ecosystem functions and biogeochemical processes. To evaluate the environmental impact of different river crab polyculture practices, we set up two different river crab () polyculture practices: one where river crabs were cultured with mandarin fish (), silver carp (), and freshwater fish stone moroko (), and another where river crabs were cultured just with mandarin fish and silver carp. These two polyculture practices were referred to as PC and MC, respectively.
