Diagram of a prawn, with the carapace highlighted in red. A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron.
A small crustacean. Carapace ovate, more long than wide; neotype measurements: 25.1 mm × 22.5 mm. [3] Females tends to have larger bodies than males; on the southern coast of Java, the carapace length is 17.6–34.9 mm in females or 18.1–27.7 in males. [4] According to Haig (1974): [5] "Carapace densely covered with sharply serrate ...
A shed carapace of a lady crab, part of the hard exoskeleton Body structure of a typical crustacean – krill. The body of a crustacean is composed of segments, which are grouped into three regions: the cephalon or head, [5] the pereon or thorax, [6] and the pleon or abdomen. [7]
The decapod (crustaceans, such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon . [1] [2] Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail:
Triops longicaudatus is a member of the crustacean class Branchiopoda, which primarily contains freshwater animals with gills on their legs. The class Branchiopoda is divided into the subclasses Sarsostraca, containing fairy shrimp, and Phyllopoda, containing all other members (cladocerans, clam shrimps, and the tadpole shrimp).
A recent study describes the newly discovered species of crustacean called Leucothoe eltoni after the famous ... the creature has also been found around Hawaii where it is considered a non-native ...
Studies of the embryonic development in Myodocopida shows that the bivalved carapace develops from two independent buds of the carapace valves. As the two halves grow, they meet in the middle. In Manawa, an ostracod in the order Palaeocopida, the carapace originates as a single element and during growth folds at the midline. [13] [14]
Abludomelita obtusata, an amphipod. Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are a part of the subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods ...
