An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.

The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.

Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.

Neither the presence nor the intensity of Hematodinium sp. parasitisation drives co-infection occurrence, severity, or diversity in the ecologically ubiquitous shore crab, Carcinus maenas.

Dramatic phenotypic divergence of crustacean mushroom bodies map to phylogenetic lineages, thereby offering unexplored opportunities for relating divergent cognitive centers to different ecologies and behavioral repertoires required to negotiate them.

Single-cell mRNA sequencing on hemocytes of penaeid shrimp revealed six types of hemocytes, type markers, differentiation pathways, and different immune roles among these subpopulations based on their transcriptional profiles.

Quantitative analyses of multi-dimensional microscopy datasets with a new Fiji/ImageJ plugin for cell tracking reveal the lineage restrictions and morphogenetic cellular behaviors underlying embryonic limb outgrowth in the direct developing crustacean Parhyale hawaiensis.

Evolutionary reconstruction of the ecdysis pathway shows that its major elements are present in the majority of metazoans, providing evidence that they originated much earlier than currently assumed.

Sexual differentiation controlled by sex-specific mRNA splicing evolved in a step-wise manner in insects.
