Next time you see a pill bug
\"Chances are that just under a nearby rock, you'll spot a roly-poly pill bug. Encourage a child to take a close look, and introduce a fascinating creature. Gently pick it up and watch as it rolls into a ball and unrolls to take a walk. This cousin to lobsters and crabs sheds its crusty skin and will tickle your hand with its 14 (count 'em!) wiggly legs. The book will inspire elementary-age children to experience the enchantment of everyday phenomena such as pill bugs\"-- Provided by publisher.

Diet of the Invasive Atlantic Blue Crab Callinectes sapidus Rathbun, 1896 (Decapoda, Portunidae) in the Guadalquivir Estuary (Spain)
The Atlantic blue crab Callinectes sapidus (Decapoda, Portunidae) Rathbun, 1896 is native to the east coasts of North and South America and has recently expanded its distribution in the non-native range into the Gulf of Cadiz (SW Iberian Peninsula, Europe). Considering the impacts caused by this invasive species in numerous estuarine ecosystems and its generalist feeding behavior, this study aims to provide the first account of the Atlantic blue crab diet on the East Atlantic coast. We studied the species’ feeding habits using stomach content analyses to predict food web interactions and putative impacts. Samples were obtained in the Guadalquivir estuary (SW Spain, Europe), which was colonized in 2017. The main food items identified on their stomach were, fish (49.9%), mollusks (44.4%) and crabs (32.3%). They also consumed plant material (27.2%), and the sediment (32.3%) in their digestive tract was likely the result of secondary ingestion. The Atlantic blue crab exhibited the same omnivorous behavior as in the native area. There was no sexual variation in diet composition or feeding activity in general, but there was a seasonal variation in the diet composition of females. The decrease of the caramote prawn Penaeus kerathurus (Forskål 1775) observed in the Guadalquivir estuary since 2021 is likely not due to the Atlantic blue crab because they seldomly eat this prey. Overall, our study provides clear baseline information to expand the knowledge about the ecological roles of the Atlantic blue crab in non-native ecosystems.

Why do lobsters eat each other? : and other odd crustacean adaptations
\"There are few behavioral adaptations that seem more odd to us than cannibalism. Scientists have noticed the rising incidence of lobster cannibals in recent years, and the reason may be connected to global warming. Readers will find the odd information about these and other crustaceans to be a fascinating study in animal adaptations, a crucial component of the elementary science curriculum.\"-- From publisher's description.

Decapod fauna from the lower Aptian in the Valencian sector of the Maestrat Basin (NE Iberia)
The Forcall Formation in the Morella and Orpesa sub-basins of the Valencian sector of the Maestrat Basin has yielded a diverse assemblage of decapod crustaceans. A total of thirteen taxa are documented, representing the infraorders Achelata, Astacidea, Glypheidea, Axiidea, Anomura and Brachyura. Among these, one new genus, three new species, and one new taxonomic combination are proposed: Viapagurus covavidrensis n. sp., Eomunidopsis rigolleti n. sp., Morellosia maestratensis n. gen., n. sp., and Distefania pimientai n. comb. Comparisons with decapod faunas from other sub-basins of the Maestrat Basin reveal a notable degree of faunal homogeneity across the region. Furthermore, the palaeobiogeographic implications of these assemblages provide new insights into the distribution and diversity of Aptian decapod crustaceans. The findings highlight a significant faunal similarity with coeval basins such as the Garraf and Basque-Cantabrian basins and underscore the potential role of the Maestrat Basin as a biogeographic corridor linking decapod faunas of the Tethyan and Boreal realms. Overall, this study contributes to a more comprehensive understanding of the decapod assemblages of the Forcall Fm. and their relationships with contemporaneous faunas in the western Maestrat Basin and beyond.

Medicinal herbs and phytochemicals to combat pathogens in aquaculture
The global production of aquaculture has grown rapidly and is dominated by China, Vietnam, and other East Asian countries. The use of antibiotics is widespread in the aquaculture industry but has been slowly decreasing as the benefits of medicinal herbs become clear. Various medicinal herbs are known to have excellent properties, such as antiviral, antibacterial, and antifungal activity; hormonal balancing; and physiological support (immune and digestive systems). The aim of this paper is to review the latest scientific information on the application of medicinal herbs in different aquaculture sectors, including marine, freshwater and crustacean culture, and the potential problems and recommendations for the application of medicinal herbs in aquaculture, to provide clues for the development of medicinal herbs for epidemic disease resistance of aquaculture industry in the future.

Tracking movements of decapod crustaceans
Decapod crustaceans are ecologically and economically important invertebrates but are vulnerable to anthropogenic pressures and climate change. Understanding their spatial ecology is essential for their management and conservation, with telemetry emerging as a useful tool to quantify space-use and movements. Here, we synthesized the use of telemetry to study decapods among articles published from 1971 to 2019 (n = 102 studies), by taxonomic group of the study species, study location, objectives, number of animals tagged and their tag recovery rate, types (and trends) of telemetry used, and IUCN conservation status. These studies revealed insight into the behaviours and roles of decapods across habitats and geographic regions. The most common study species were crayfish and lobsters (41 %, Astacidea), and these studies also had the highest number of individuals tagged per study (mean = 149 individuals). Most studies (86 %) were conducted in the northern hemisphere. Acoustic tags were the most commonly used equipment (66 % of studies) and were first employed in 1971, followed by radio-telemetry (mid-1990s), passive integrated transponders (mid-2000s), and data storage tags (late 2000s). Almost half (48 %) of studies focused on species that had a conservation status of Least Concern, perhaps reflecting an applied science focus on animals of commercial interest rather than conservation importance. The positive allometric relationship between body length and movement rate (exponent = 0.86) demonstrates the type of broader ecological insight that combining these studies can provide. Tracking decapod movements will likely become increasingly important for managing fisheries, protecting sensitive species, and understanding invasion biology.

Applications of chitosan in food, pharmaceuticals, medicine, cosmetics, agriculture, textiles, pulp and paper, biotechnology, and environmental chemistry
Chitosan is a biopolymer obtained from chitin, one of the most abundant and renewable materials on Earth. Chitin is a primary component of cell walls in fungi, the exoskeletons of arthropods such as crustaceans, e.g., crabs, lobsters and shrimps, and insects, the radulae of molluscs, cephalopod beaks, and the scales of fish and lissamphibians. The discovery of chitin in 1811 is attributed to Henri Braconnot while the history of chitosan dates back to 1859 with the work of Charles Rouget. The name of chitosan was, however, introduced in 1894 by Felix Hoppe-Seyler. Chitosan has attracted major scientific and industrial interests from the late 1970s due to its particular macromolecular structure, biocompatibility, biodegradability and other intrinsic functional properties. Chitosan and derivatives have practical applications in the food industry, agriculture, pharmacy, medicine, cosmetology, textile and paper industries, and in chemistry. In recent years, chitosan has also received much attention in dentistry, ophthalmology, biomedicine and bioimaging, hygiene and personal care, veterinary medicine, packaging industry, agrochemistry, aquaculture, functional textiles and cosmetotextiles, catalysis, chromatography, beverage industry, photography, wastewater treatment and sludge dewatering, and biotechnology. Nutraceuticals and cosmeceuticals are actually growing markets, and therapeutic and biomedical products should be the next markets in the development of chitosan. Chitosan is also the object of numerous fundamental studies. In this review, we highlight a selection of works on chitosan applications published over the past two decades.
