Der Spitzschwanz-Mondfisch (Masturus lanceolatus (Gr.: „mastax“ = Biss, „oura“ = Schwanz; Lat.: „lanceolatus“ = lanzettlich)) ist eine seltene und wenig bekannte Art der Mondfische (Molidae). Das Verbreitungsgebiet der Art ist nur ungenau bekannt. Möglicherweise kommt die Art weltweit in tropischen und gemäßigten Meeren vor. Sie lebt in Tiefen bis 670 Metern.
Der Spitzschwanz-Mondfisch erreicht eine Maximallänge von 3,3 Metern und ein Maximalgewicht von zwei Tonnen. Im Unterschied zum bekannteren Mondfisch (Mola mola) ist der Körper des Spitzschwanz-Mondfisches nicht mühlsteinartig rund, sondern oval und 1,5 mal länger als hoch. Der mittlere Teil der Scheinschwanzflosse (Clavus) ist verlängert und bildet die namensgebende Spitze. Sie ist bei Jungfischen sehr lang und wird mit zunehmendem Alter kürzer. Die übrige Schwanzflosse ist nicht wellförmig, wie bei Mola mola. Rücken- und Afterflosse stehen einander symmetrisch gegenüber, sind hoch und schmal und werden von 15 bis 19 flossenstrahlenähnlichen Knorpelstäben gestützt. Beide Flossen stehen weit hinten am Körper.

The sharptail mola (Masturus lanceolatus) is a species of mola found circumglobally in tropical and temperate waters. It is similar in appearance to the ocean sunfish (Mola mola), but can be distinguished by the projection on its clavus (pseudo-tail). Other common names include sharpfin sunfish, point-tailed sunfish, and trunkfish.[3][4] Rarely encountered, very little is known of the biology or life history of the sharptail mola. It has recently become important to commercial fisheries operating off eastern Taiwan.[5] This species is the only member of its genus.[6]
The distribution of the sharptail mola is worldwide in tropical and temperate waters.[3] They are primarily inhabitants of the epipelagic zone, but are rarely sighted at the surface, with many of those appearing to be ill and parasite-ridden. During the day, they spend most of their time at depths of 5–200 m (16–656 ft), preferring water temperatures above 20 °C, but making repeated dives into cooler, deeper water, possibly to feed or to avoid predators. At night, they spend most of their time between 100 and 250 m (330 and 820 ft). They have been sighted in the mesopelagic zone to a depth of 670 m (2,200 ft), but may descend to over 1,000 m (3,300 ft). One tagged individual in the Gulf of Mexico moved an average of 10 km (6.2 mi) a day.[7][8]
One of the largest bony fishes, the sharptail mola can measure up to 3.4 m (11 ft) long and weigh 2,000 kg (4,400 lb).[3] It has an oval body with an evenly convex forehead profile. The eyes are placed more forward on the head than in the genus Mola. The teeth in both jaws are fused into beak-like plates. The dorsal and anal fins are placed posteriorly, and the base of the dorsal fin is longer than that of the anal fin. In place of a caudal fin, the dorsal and anal fins merge into a clavus, formed by 18-20 fin rays. The central rays in the clavus are supported by the last vertebra and form an elongated triangular lobe; some authors believe these rays to be remnants of the larval caudal fin, though this is disputed.[4][9][10]
Their skin is covered with small dermal denticles that are finer than those of the ocean sunfish. Their coloration is silvery with the upper parts of the sides grayish brown to blackish. The sides may bear ill-defined dark spots. The dorsal and anal fins are slate gray, while the clavus may have pale blotches.[11] This species is distinguished from the similar Masturus oxyuropterus by its prominent chin, the lack of a concavity above the eyes, and the unequal lengths of the dorsal and anal fin bases. These two forms may represent different sexes of the same species.[10]
Robert Collett, who examined some of the first known specimens of sharptail mola, speculated they might represent abnormal ocean sunfishes that had retained larval characteristics. However, the caudal projection is now known to be a secondary development that follows the loss of the primary tail.[12] The swimming mode of the sharptail is similar to that of other ocean sunfishes, using sculling motions of its long dorsal and anal fins to propel itself through the water. The anal fin moves more extensively than the dorsal fin. The small pectoral fins move constantly to control pitch, while the clavus is employed as a rudder.[7]
Juvenile sharptail molas are known to feed on benthic annelids and sponges. Adults likely feed on medusae, siphonophores, ctenophores, and salps, as well as some fishes, crustaceans, and molluscs.[7] Sharptail molas sometimes have remoras attached to the surface of their bodies or inside their buccal cavities. In 1949, a sharptail mola off North Carolina was found with a common remora (Remora remora) wedged inside the gill arches on its right side. This evidently impaired the respiration of the mola, such that it foundered on the beach and was collected by fishermen.[13]
Molas are oviparous and are amongst the most fecund of all fishes. Larval sharptail molas are rounded in shape and develop large pyramidal dermal spines over their bodies, which persist through a prejuvenile phase called the "Molacanthus" stage. In this stage, the body is deep and compressed, with a thin, keel-like structure below the abdominal region. This ridge is made from skin and covered with several rows of small spines. The skin is rough, being covered with small prickles. The spines eventually diminish in size and disappear, leaving scars obvious on the sides of young fish up to 70 mm (2.8 in) long. Their coloration is dark brown on the back, becoming very light on the sides and belly.[14][15] The lifespan for this species is estimated to be 85 years for males and 105 years for females.[5]
Since 2002, promotion of an ocean sunfish festival in Hualien County, Taiwan, has increased demand for the meat of the sunfish (called "mambo fish" after a public vote), whereas before only the intestines and reproductive organs were sold while the rest of the fish was discarded. The month-long April festival draws some 120,000 visitors, and features "101 ways to eat" sunfish. Consequently, catches of sunfishes off eastern Taiwan have risen sharply, with the sharptail mola comprising 90% of the catch. In 2005, 208 tonnes were landed and the annual sunfish catch was valued at US$ one million. The species is caught by set net, drift net, and longline fisheries. The impact of this increased exploitation on sunfish stocks is under investigation.[5][16][17]
On Wednesday 30 November 2022, the carcass of a 450-pound Sharptail mola was found ashore on a beach in North Carolina. It was kept by the North Carolina Museum of Natural Sciences.[18]

ヤリマンボウ(学名;Masturus lanceolatus)は、世界中の温帯、熱帯の海に生息するマンボウ科の海水魚。日本でも、日本海や伊豆諸島近海などでみられる。外見上は、マンボウと似ているが、舵びれ(背びれと尻びれの一部が変形したもの)に突出部があることで区別できる。外洋に生息し、発見例は少ないため、生態には未だ謎が多い。
ヤリマンボウは世界中の温帯・熱帯海域に生息している[1]。 海面近くでは普通みられないが、寄生虫等のために調子の悪い個体などが稀に姿を現す。日中はほとんどの時間を水深5m-200mの海中で過ごし、 夜には、100m-250mまでの深さに位置することが多い。20℃以上の水温を好むものの、外敵から逃れたり、餌を得るためにしばしばそれより水温の低い深度まで潜ることが有る。また、670mまでの水深でみられることもあるため、水深1000m以上潜ることもあると推測されている。メキシコ湾の個体について行った調査では、一日に平均で10kmを泳ぐことが分かっている[2][3]。
硬骨魚綱で最も大きい種の一つである本種は、成体で全長3.4m、重量2000kgにまで達する[1]。 目は、マンボウ属の魚よりも前方の頭部についている。 両顎の歯は、嘴のような板としてそれぞれ一体化している。背びれと尻びれは体の後方に位置し、背びれの基底部は尻びれのそれより長くなっている。尾びれの位置には、背びれと尻びれの一部が結合した舵びれがあり、18-20の鰭条がある。舵びれの、中央の鰭条は脊椎骨に支えられており、三角形の突出を作り出している。この突出は、本種の幼魚期にみられる尾びれの名残であるとの主張も有り、議論が続けられている[4][5][6]。
皮膚は、マンボウよりも細かい小歯状の突起で覆われている。体色は銀色で、体側面の上部は灰色がかった茶色から黒色。背びれと尻びれは濃い青灰色で、舵びれには青白い斑がみられることもある [7]。近縁種のトンガリヤリマンボウ(Masturus oxyuropterus)は、突出した顎などで本種と区別されるが、それらは同種の性別間による差異で、この二種は別種ではないという主張もある[6]。
本種の泳ぐ方法は他のマンボウのそれと類似しており、長い背びれと尻びれをオールのように使い、水の中を進む。小さな胸びれは、体の傾きを調整するために一定のペースで動き、一方、舵びれはその名の通り舵の役割をする[2]。
若魚はプランクトンや海綿動物、成魚はクラゲやオキアミ、小魚などを食べる[2]。本種の体表面や、頬の内部には時たまコバンザメが付いている。1949年にはノースカロライナで、右鰓弓の内部にコバンザメが入った状態の本種が発見された。コバンザメがその個体の呼吸を阻害したために、砂浜に打ち上げられたところを地元の漁師が発見したのである[8]。
マンボウは卵生で、魚類の中で最も多くの卵を産むと言われる。幼生の肌は粗く、とげに覆われている。このとげは成長に従い減少し、消えていくが、体長70mmに達する頃まで痕跡が残る。その体色は体背面が焦げ茶で、側面から覆面にかけて明るい色になる[9][10]。本種の寿命はおよそ、オスで85年、メスで105年とされている[11]。
かつては、腸や卵巣などだけが売られ他の部分は廃棄されていたのに対して、近年台湾では本種の魚肉の需要が増加している。花蓮県では2002年からマンボウ肉の消費促進を目指した祭り「花蓮曼波季」が開催されている。4月から一ヶ月続くこの祭りは、様々なマンボウ料理を目玉として、120,000人ほどを集客する。結果として台湾東部でのマンボウの漁獲量は大幅に増加しており、本種はその90%を占めている。 2005年には、208トンが水揚げされ、一年のマンボウの漁獲高は100万USドルにまで達した。この大幅な漁獲量の増加が本種の個体数に与える影響については、現在各方面で調査中である[11][12][13]。

물개복치(학명:Masturus lanceolatus)는 복어목 개복치과에 속하는 물고기이다. 몸길이는 3.4m로 대형어류에 속한다.
물개복치는 몸이 전체적으로 노란색의 몸을 가지고 있으며 배쪽에는 흰색의 점이 나 있는 특징을 가지고 있다. 눈이 다른 개복치들에 비해 앞으로 쏠려 있으며 두 턱의 치아는 부리처럼 부드럽게 융화되어 있다. 등갈과 항문지느러미는 후방으로 치우쳐 있고 등지느러미의 베이스는 항문 지느러미보다 더 길다. 피부는 해파리보다도 작은 미세한 섬모로 구성되며 등점과 항문지느러미는 회색을 띄고 있다. 등쪽과 항문지느러미에는 18~20개의 핀 광선에 의해 형성된 클라비우스로 결합이 되며 클라비우스의 중앙 광선은 마지막 척추에 의해 지원되고 길쭉한 삼각형의 엽을 형성한다. 먹이로는 멸치, 청어와 같은 작은 물고기와 해파리를 주로 먹는 육식성물고기에 속한다.
물개복치의 주요한 서식지는 태평양과 대서양 인도양 등의 아열대 해역이며 수심 0~617m까지 광범위하게 서식하는 표해수대와 중심해의 어류이다. 대한민국의 남해에서도 서식이 확인되는 어종이며 주로 연안이나 대륙붕으로 이뤄진 지역에 서식한다. 물개복치는 낮애 5~200m의 얕은 표해수층에서 먹이활동을 하다가 밤이 되면 100~250m의 좀더 깊은 곳에서 쉬는 물고기이기 때문에 주행성 어류에 속하고 대체적으로 표해수대에서 가장 많은 활동을 보이는 어종이기 때문에 물개복치는 통상적으로 표해수대의 어류로 분류한다.
