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.
Lobster anatomy includes two main body parts: the cephalothorax and the abdomen. The cephalothorax fuses the head and the thorax, both of which are covered by a chitinous carapace. The lobster's head bears antennae, antennules, mandibles, the first and second maxillae. The head also bears the (usually stalked) compound eyes. Because lobsters ...
A pair of slipper lobster (Scyllaridae) larvae. After hatching out of their eggs, young slipper lobsters pass through around ten instars as phyllosoma larvae — leaf-like, planktonic zoeae. [10] These ten or so stages last the greater part of a year, after which the larva moults into a "nisto" stage that lasts a few weeks. Almost nothing is ...
Malacostraca is the second largest of the six classes of pancrustaceans behind insects, containing about 40,000 living species, divided among 16 orders.Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, spiny lobsters, crayfish, shrimp, krill, prawns, woodlice, amphipods, mantis shrimp, tongue-eating lice and many other less familiar animals.
Nephrops norvegicus at Cretaquarium in Greece. Nephrops norvegicus has the typical body shape of a lobster, albeit narrower than the large genus Homarus. [3] It is pale orange in colour, and grows to a typical length of 18–20 centimetres (7–8 in), or exceptionally 25 cm (10 in) long, including the tail and claws. [4]
The Lobster Conservatory includes information on the biology and conservation of lobsters. The majority can be applied to crayfish due to common ancestry and homology. Neural and tail anatomy provides an idea of the organization of the segmental ganglia in the tail of the crayfish. The second diagram on the page is a transverse section through ...
Cutaway diagram of a barnacle, with antennae highlighted by arrow. Crustaceans bear two pairs of antennae. The pair attached to the first segment of the head are called primary antennae or antennules. This pair is generally uniramous, but is biramous in crabs and lobsters and remipedes.
Lobster bisque, lobster stock, and lobster consommé are made using lobster bodies (heads), often including tomalley. In Maryland and on the Delmarva Peninsula , the hepatopancreas of the blue crab is called the "muster" or "mustard", probably because of the yellow color, which is not the bright yellow of regular prepared yellow mustard , but ...
