= Homarus gammarus =
= = Description = =
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 ) . Like other crustaceans , lobsters have a hard exoskeleton which they must shed in order to grow , in a process called ecdysis ( moulting ) . This may occur several times a year for young lobsters , but decreases to once every 1 – 2 years for larger animals .
The first pair of pereiopods is armed with a large , asymmetrical pair of claws . The larger one is the " crusher " , and has rounded nodules used for crushing prey ; the other is the " cutter " , which has sharp inner edges , and is used for holding or tearing the prey . Usually , the left claw is the crusher , and the right is the cutter .
The exoskeleton is generally blue above , with spots that coalesce , and yellow below . The red colour associated with lobsters only appears after cooking . This occurs because , in life , the red pigment astaxanthin is bound to a protein complex , but the complex is broken up by the heat of cooking , releasing the red pigment .
The closest relative of H. gammarus is the American lobster , Homarus americanus . The two species are very similar , and can be crossed artificially , although hybrids are unlikely to occur in the wild since their ranges do not overlap . The two species can be distinguished by a number of characteristics :
The rostrum of H. americanus bears one or more spines on the underside , which are lacking in H. gammarus .
The spines on the claws of H. americanus are red or red @-@ tipped , while those of H. gammarus are white or white @-@ tipped .
The underside of the claw of H. americanus is orange or red , while that of H. gammarus is creamy white or very pale red .

= = Distribution = =
Homarus gammarus is found across the north @-@ eastern Atlantic Ocean from northern Norway to the Azores and Morocco , not including the Baltic Sea . It is also present in most of the Mediterranean Sea , only missing from the section east of Crete , and along only the north @-@ west coast of the Black Sea . The northernmost populations are found in the Norwegian fjords Tysfjorden and Nordfolda , inside the Arctic Circle .
Attempts have been made to introduce H. gammarus to New Zealand , alongside other European species such as the edible crab , Cancer pagurus . Between 1904 and 1914 , one million lobster larvae were released from hatcheries in Dunedin , but the species did not become established there .
= = Ecology = =
The diet of H. gammarus mostly consists of other benthic invertebrates . These include crabs , molluscs , sea urchins , starfish and polychaete worms .
The three clawed lobster species Homarus gammarus , H. americanus and Nephrops norvegicus are hosts to the three known species of the animal phylum Cycliophora ; the species on H. gammarus has not been described .
Homarus gammarus is susceptible to the disease gaffkaemia , caused by the bacterium Aerococcus viridans . Although it is frequently found in American lobsters , the disease has only been seen in captive H. gammarus , where prior occupation of the tanks by H. americanus could not be ruled out .
= = Human consumption = =
Homarus gammarus is traditionally " highly esteemed " as a foodstuff and was mentioned in " The Crabfish " a seventeenth century English folk song . It may fetch very high prices and may be sold fresh , frozen , canned or powdered . Both the claws and the abdomen of H. gammarus contain " excellent " white meat , and most of the contents of the cephalothorax are edible . The exceptions are the gastric mill and the " sand vein " ( gut ) . The price of H. gammarus is up to three times higher than that of H. americanus , and the European species is considered to have a better flavour .
Aquaculture systems for H. gammarus are under development , and production rates are still very low .
= = Taxonomic history = =
H. gammarus is the type species of the genus Homarus Weber , 1795 , as determined by Direction 51 of the International Commission on Zoological Nomenclature . Prior to that direction , confusion arose because the species had been referred to by several different names , including Astacus marinus Fabricius , 1775 and Homarus vulgaris H. Milne @-@ Edwards , 1837 , and also because Friedrich Weber 's description of the genus had been overlooked until rediscovered by Mary Rathbun , rendering any prior assignments of type species ( for Homarus H. Milne @-@ Edwards , 1837 ) invalid for Homarus Weber , 1795 .
The type specimen of Homarus gammarus was a lectotype selected by Lipke Holthuis in 1974 . It came from 57 ° 53 ′ N 11 ° 32 ′ E , near Marstrand , Sweden ( 48 kilometres or 30 miles northwest of Gothenburg ) , but both it and the paralectotypes have since been lost .
The common name for H. gammarus preferred by the Food and Agriculture Organization is " European lobster " , but the species is also widely known as the " common lobster " .

During January 1942 , No. 2 Squadron 's aircraft were dispersed at Penfui , Boeroe Island , and Darwin . The Penfui detachment attacked Japanese shipping taking part in the invasion of Celebes . Two Hudsons shot down or damaged three Japanese floatplanes that attacked them as they were bombing a transport ship on 11 January ; the next day both Hudsons were themselves shot down by Mitsubishi Zeros . Penfui was bombed by the Japanese for the first time on 26 January 1942 , and attacked regularly thereafter , damaging some aircraft . The intact Hudsons were withdrawn to Darwin but Headlam and his staff remained at Penfui to enable the base to be used by aircraft during reconnaissance missions from Australia . On 18 February , Headlam was ordered to evacuate all his personnel except a small party to demolish the airfield with assistance from Sparrow Force . He returned to Darwin the following day , just as the city experienced its first raid by the Japanese . Four of No. 2 Squadron 's Hudsons were destroyed in the attack ; the remainder were relocated to Daly Waters , where they continued to carry out reconnaissance and bombing missions against Japanese targets in Timor .

= = History = =
Two realignments in 1963 and 1964 rerouted the western end of the highway again . This time it was realigned to run from Hesperia to New Era , bypassing Ferry . A larger change around 1969 reconfigured the highway designations in Oceana County . M @-@ 20 replaced M @-@ 82 west of Hesperia , to end at New Era instead of Muskegon . The new M @-@ 120 designation replaced M @-@ 20 south of Hesperia . M @-@ 82 now ran from Hesperia to Newaygo only . The length of the highway was increased in 1973 when the eastern end was moved back to Howard City . M @-@ 46 was rerouted to follow the US 131 freeway south of Howard City to Cedar Springs , and replaced M @-@ 57 between Cedar Springs and Casnovia . This freed up the Newaygo to Howard City highway for a return to the M @-@ 82 designation . The last change came in 1978 when the concurrency with M @-@ 120 was eliminated in favor of M @-@ 120 . The M @-@ 82 designation was truncated at this time to the junction west of Fremont , resulting in the current highway routing .

= = Creation and conception = =
Masashi Kishimoto has noted that he likes Shikamaru due to his easygoing nature despite being a genius , and contrasted him against Sasuke Uchiha 's intelligent but abrasive personality . Kishimoto also comically remarked that he would marry Shikamaru if he were a girl , noting that Shikamaru would likely be successful in life . When designing Shikamaru 's Part II appearance , Kishimoto wanted to give Shikamaru a unique appearance despite drawing him with a vest that several other ninja wear in the series . As a result , he drew his forehead protector on his arm in order to not obscure his hair .
= = Appearances = =
Shikamaru first major appearance in the series is during the Chunin Exams , bi @-@ yearly exams for ninja who wish to advance in rank . He is part of Team 10 alongside Choji Akimichi and Ino Yamanaka . He is a highly unenthusiastic person , and he attempts to go through life with minimum effort . Contrary to his lazy tendencies , Shikamaru is extremely intelligent ; his teacher , Asuma Sarutobi , determined that Shikamaru 's IQ was over 200 . Shikamaru 's abilities are based on the Shadow Imitation Technique ( 影真似の術 , Kagemane no Jutsu , English TV : " Shadow Possession Jutsu " ) , the signature technique of his clan , with which he merges his shadow with an opponent 's shadow , making them immobilized and forced to mimic Shikamaru 's movements . As the series progresses , Shikamaru becomes able to manipulate his shadow in new ways . By Part II of the series , Shikamaru is capable of utilizing multiple shadow @-@ based techniques at once and can lift his shadow from the ground in order to interact with physical objects ; for instance , he can pierce enemies with the shadow tendrils or use them to throw weapons .
Shikamaru approaches the exams with a sense of apathy ; when he battles the Sunagakure ninja Temari , he defeats her but forfeits his match to her , due to his chakra being low . Despite this loss , he is the only ninja among his peers to be promoted to the rank of Chunin , as the overseers of the exams were impressed by the insight and intelligence he demonstrated against Temari . As a Chunin , Shikamaru is appointed the leader of a team to prevent Sasuke Uchiha from defecting to the village of Otogakure . Although Shikamaru 's team manages to defeat the Otogakure ninja barring their way , Sasuke manages to escape .
In Part II of the series , Shikamaru is assigned the task of locating two members of the criminal organization Akatsuki . While his team manages to find their targets , the immortal Akatsuki member Hidan kills Asuma Sarutobi during the course of the battle despite Shikamaru 's best efforts . After Asuma 's funeral , Shikamaru sets out with the surviving members of Team 10 to avenge their mentor with the aid of Kakashi Hatake . As the other deal with Hidan 's partner Kakuzu , Shikamaru avenges Asuma by defeating Hidan and making sure the Akatsuki member 's body is never found . Following the fight , Shikamaru vows to protect Kurenai Yuhi and Asuma 's newborn daughter . He is later assigned to the Fourth Division alongside Temari and Chōji . He is named a proxy general under Gaara . In the series epilogue , stating his personal desire during the series of final battles , Shikamaru becomes advisor to the Seventh Hokage Naruto after marrying Temari and gaining a son in Shikadai Nara .
A light novel titled Shikamaru Hiden : A Cloud Drifting in Silent Darkness , written by Takashi Yano and illustrated by Kishimoto , stars Shikamaru as the main character and narrator . The novel is set two years after the Fourth Ninja War , focusing on Shikamaru 's assignment as organizer of the newly formed Shinobi Union to capture a rogue ninja who rules over the distant Land of Silence and attempts to establish a new world order ruled by the common people . It also explores his growing relationship with Temari , culminating in him struggling to name his child with her , years after the end of the novel .
