The American lobster was first described by Thomas Say in 1817, with a type locality of "Long-branch, part of the coast of New Jersey". [2] The name Say chose – "Astacus marinus" – was invalid as a junior homonym of Astacus marinus Fabricius, 1775, which is in turn a junior synonym of Homarus gammarus. [2]
Lobster is commonly served boiled or steamed in the shell. Diners crack the shell with lobster crackers and fish out the meat with lobster picks. The meat is often eaten with melted butter and lemon juice. Lobster is also used in soup, bisque, lobster rolls, cappon magro, and dishes such as lobster Newberg and lobster Thermidor.
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]
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 ...
On this European lobster, the right claw (on the left side of the image) is the crusher and the left claw is the cutter.. Homarus gammarus is a large crustacean, with a body length up to 60 centimetres (24 in) and weighing up to 5–6 kilograms (11–13 lb), although the lobsters caught in lobster pots are usually 23–38 cm (9–15 in) long and weigh 0.7–2.2 kg (1.5–4.9 lb). [3]
The names of these genera have become generalised to cover specific larval stages across wide groups of crustaceans, such as zoea and nauplius. Other terms described forms which are only found in particular groups, such as the glaucothoe of hermit crabs , or the phyllosoma of slipper lobsters and spiny lobsters .
The adult female consists of three parts, the cephalothorax, a thorax bearing two large lateral expansions or wings, and the abdomen which is responsible for carrying two oval egg-sacs. The female Nicothoe astaci abdomen tip measures 1.2–1.3 millimetres (0.047–0.051 in), and each wing measures 4 mm (0.16 in) long.
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 ...
