Summary: Slipper and spiny lobsters exhibit a complex life cycle with a planktonic larval phase called phyllosoma. The morphology of phyllosoma larvae has been believed to be constant over evolutionary history, but recent evidence suggests large morphological changes and diversification. The study found that there were two bursts of lineage diversification in the evolutionary history of these lobsters, and the morphological disparity followed these bursts. The results indicate that diversification in Achelata involves nonadaptive radiation processes.

Summary: Representatives of the family Synaxidae, commonly known as furry lobsters, were more common in the past, especially during the Late Jurassic in Europe. This study presents an overview of known extant and extinct synaxids, including the discovery of a new fossil form, Palaeosynaxes montserratae nov. gen., nov. sp., which extends the geographical range of this group. The fossil was found in reefal limestones near Krakow, southern Poland, and represents one of the earliest records of furry lobsters worldwide.

Summary: The study revealed that the distribution of mid- and late-stage phyllosomata in the oceanic waters of the Mexican Caribbean is mainly influenced by the swift Yucatan Current, despite the presence of some local features that may favor short-term retention. The strong Yucatan Current promotes extensive mixing of organisms, facilitating the advection of phyllosomata in the region.

Summary: The study proposed fecundity equations for two main Brazilian species of spiny lobster for the first time, showing a decline in fecundity levels over decades but partial recovery after the implementation of a 6-month closed season. This suggests that the measure has been effective in protecting lobster reproduction and allowing stocks to recover.

Summary: Mutations can cause the evolution and diversification of color phenotypes in animals. This study focuses on freshwater crayfish and found that color variants, especially blue-colored ones, are common. The reason behind these variants and their potential for adaptive evolution is still unknown. The study suggests that conspicuous colors in some crayfish species may be a neutral trait due to limited migration and gene flow. More genetic studies and behavioral experiments are needed to test this hypothesis.

Summary: The taxonomy of North American crayfishes has gained significant interest due to the increasing threat to these crustaceans. This study utilizes anchored hybrid enrichment (AHE) data to resolve the phylogeny of the burrowing crayfish genus Lacunicambarus, providing insights into the evolutionary history and interspecific relationships within this group. The findings highlight the valuable contributions that next-generation sequencing methods such as AHE can make to crayfish taxonomy and conservation.

Summary: This study provides a detailed description of the morphology of the first three postembryonic developmental stages in representatives from four crayfish families. It also constructs a phylogenetic tree of freshwater Astacidea based on new diagnostic juvenile characters and discusses the evolutionary history of maternal care in freshwater crayfish.

Summary: This study provides the first insight into the transcriptomic regulation of the gut during PaV1 infection in Caribbean spiny lobster. The analysis reveals differential gene expression related to transcriptional regulation, protein signaling, transmembrane transport, among others. These findings contribute to understanding the molecular mechanisms involved in PaV1-P. argus interaction.

Summary: The distribution patterns of South American freshwater crayfish species were analyzed using panbiogeographical track analysis, revealing two generalized tracks. The results indicate that the crayfish are primarily distributed in Atlantic coastal sub-tropical and Pacific coastal temperate wet climate regions of South America, showing biogeographical similarities to other inland water decapods.

Summary: A nearly complete specimen of a new species of palinurid lobster, Linuparus qualitus, was discovered in northeastern British Columbia, Canada. The anatomically almost complete specimen includes the cephalothorax, anterior appendages, and most of the pleon, with an antennal stridulating mechanism similar to the extant species L. trigonus.

Summary: Information about longevity and mortality of decapod crustaceans, especially crayfishes, is limited but crucial for understanding the dynamics of exploited populations. In this study, we estimated the longevity and natural mortality of the burrowing crayfish Parastacus pugnax in Chile, finding a lifespan range of 8.2 to 12.4 years and a mortality rate of 0.241 to 0.611 per year.
