During diving explorations of anchialine cave systems on Abaco Island, Bahamas, we collected five larvae that represent different developmental stages of remipede crustaceans. Based on four early naupliar stages and a post-naupliar larva, it is possible for the first time to reconstruct the postembryonic development of Remipedia some 25 years after their discovery. These specimens begin to fill...

A novel visual capability, the detection of circularly polarised light, has been demonstrated in a mantis shrimp, a colourful crustacean from tropical reefs.

Aim of the current piece work was to study food composition and feeding intensity Channa striata from Krishna river June, 2019 July 2020. The gut contents were analysed three stations undertaken fish. major components items in fish was: fishes their larvae, crustaceans, insect annelids with semi digested material unidentified items. Fishes are identified as teleost, particularly carps cat larva...

Selenoproteins (Sels) are involved in oxidative stress regulation. Glutathione peroxidase (GPx) and thioredoxin reductase are among the most studied Sels in crustaceans. Since their expressions and activities are affected by pathogens, environmental and metabolic factors, their functions might be key factors to orchestrate the redox cellular balance. The most studied invertebrate selenoproteome...

Autonomie temperature regulation in crustaceans has been the subject of various studies. These included measurements of body temperature (e.g., Edney, 1951a, 1953; Warburg, 1965), lethal limits of ambient temperature (e.g., Edney, 1964; Orr, 1955), water loss by evaporation (e.g., Edney, 1951b; Warburg, 1965), and respiratory metabolism (e.g., Demeusy, 1957; Edwards & Irving, 1943). Behavioral ...

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fi...

Shellfish (crustaceans and mollusks) have long been known as a common cause of allergic reactions to food. Like other food allergies, the allergic reactions to shellfish involve IgE-mediated Type I hypersensitivity. Biochemical and molecular studies have documented the major shrimp allergen is the muscle protein tropomyosin. Subsequent molecular cloning studies on lobsters and crabs have charac...

Mushroom bodies are the iconic learning and memory centers of insects. No previously described crustacean possesses a mushroom body as defined by strict morphological criteria although crustacean centers called hemiellipsoid bodies, which serve functions in sensory integration, have been viewed as evolutionarily convergent with mushroom bodies. Here, using key identifiers to characterize neural...

Seafood products have attracted considerable attention as important sources of nutrients in the human diet. Apart from their delicacy, crustaceans species such as shrimps and crabs consist of protein and amino acids. The present study was conducted to evaluate flesh of both sexes of mantis shrimp, shrimp and crab species with the emphasis on protein and amino acids composition. The results show...
