Seekröten ( German )

provided by wikipedia DE

Die Seekröten (Chaunacidae) sind eine Fischfamilie aus der Ordnung der Armflosser (Lophiiformes). Sie leben im Atlantik, Pazifik und Indischen Ozean über den Kontinentalabhängen.[1][2]

Merkmale

Die großköpfigen Fische haben einen weichen Körper mit kleinen, stachligen Schuppen und ein gut ausgebildetes, nicht mit Schuppen bedecktes Seitenliniensystem auf Kopf und Rumpf. Das große Maul ist aufwärts gerichtet. Die Zähne im Kiefer und auf dem Gaumen sind klein und in Reihen angeordnet. Der erste Strahl der Rückenflosse ist zur „Angel“ (Illicium) umgebildet, weitere Hartstrahlen sind nicht vorhanden. Die Angel kann in eine unbeschuppte U-förmige Vertiefung verborgen werden. Die Afterflosse hat fünf bis sieben Weichstrahlen, die Rückenflosse zehn bis zwölf. Seekröten sind pink bis tief orangerot gefärbt. Die Fische werden 7 bis maximal 40 Zentimeter lang.[1][2]

Die kleinen, ovalen Kiemenöffnungen liegen hinter dem Bauchflossenansatz. Die Kiemenkammern der Seekröten sind voluminös und sehr dehnbar. Im Laufe eines Atemzyklus nehmen die Fische darin so viel Wasser auf, dass das Körpervolumen um 20 bis 30 % zunimmt. Die Atemzyklen sind langsam; einer kann bis zu 4 Minuten dauern.[3]

Sea toad

provided by wikipedia EN

The sea toads and coffinfishes are a family of deep-sea anglerfishes known as the Chaunacidae.[1]

These are bottom-dwelling fishes found on the continental slopes of the Atlantic, Indian, and Pacific Oceans,[2] at depths to at least 2,460 m (8,070 ft). There have also been findings of deep-sea anglerfishes off the coasts of Australia and New Caledonia.[3] Other findings suggest some genera of Chaunacidae are found near volcanic slopes encrusted with manganese.[3] Of the two genera in the family, Chaunacops typically occurs at deeper depths than Chaunax, but with considerable overlap.

Chaunax pictus

They have large, globose bodies and short, compressed tails, and are covered with small, spiny scales. The largest are about 30 cm (12 in) in length. During their gill ventilatory cycle, Chaunacidae are able to take in high volumes of water, increasing their total body volume by 30%.[4] The first dorsal fin ray is modified into a short bioluminescent lure which dangles forward over the mouth, which is turned upwards so as to be nearly vertical. The sensory canals of the lateral lines are especially conspicuous.[5] Chaunax have modified fins which resemble legs.[6] It was also found that they use these modified pelvic fins to assist with maneuvering their swimming, especially when as an escape response.[7]

Sea toads are mostly sedentary fish, and rely on a more opportunistic way of hunting where they prey on anything within reach.[8] The sensory canals of the lateral lines are especially conspicuous, and confers advantages in avoidance of predators and consumption of prey.[8]

Sexual Dimorphism

A species from Chaunacidae, Chaunacops melanostomus, exhibits a single trait showing sexual dimorphism. Sample collection shows that males tend to have larger nostrils than females, and even in the smallest males, nostrils tend to be very apparent.[3]

Distribution and Habitat

We currently know of 3 species of Chaunocops that live in the Indo-west Pacific Ocean, which are C. coloratus, C. melanostomus and C. spinosus.[3] However, members of the family Chaunacidae have been collected from the Eastern Indian Ocean, the Eastern Pacific Ocean, and the Western Atlantic Ocean, showing that this family is relatively widely distributed. Namely, in 1989 a study was done by John H. Caruso in which 21 specimens of Chaunacid fish were collected off the western coast of Australia, many of which were collected at approximately -30° latitude, and approximately 90° longitude. These specimen were from the genus Bathychaunax, which before this study only contained 2 other species: B. coloratus of the Eastern Pacific, and B. roseus from the Western Atlantic. The new species of Bathychaunax was found at depths between 1320 m and 1760 m.[9] Furthermore, in 2015 an article was published indicating that new specimens from the genus Chaunacops were found off the coasts of Australia and New Caledonia.[3]

In addition, it was found that the Chaunacops coloratus are also often found near "manganese-encrusted volcanic talus slopes". The fish were observed to often have one of their pectoral fins in sediment and another one on a rock in order to make it seem as though they were wedged between two substrates. The average oxygen concentration was found to be about 1.59 mL/L at the depths they were found and the average temperature was about 1.68 °C. Salinity in their habitats did not change much and was found to be an average of 34.64 psu.[7]

Anatomy

Chaunocops spinosis

Upon collection and examination of this species, it is observed to have several distinct physical attributes. One trait is the fine dermal spinules, along with simple and bifurcate dermal spinules, covering the body. It also has four pectoral lateral-line neuromasts, which are sensory organs characteristic to fish and aquatic organisms. It has a greyish mouth, and semi-transparent, light-greyish skin. Inside the mouth are several rows of teeth. There are three or four rows of small canine teeth on the upper jaw, and three rows of the same on the lower jaw. The skin of the head, belly, and most of gill chamber is dark blue, and it has a relatively short tail. As for the overall body structure, body is resemblant of a tadpole, with a more globular shape in the anterior which tapers in the posterior. The eyes are covered by transparent skin and are very small.[3]

Chaunacops melanostomus

Another species in the same genus was collected with similar traits to the above species, but some noticeable differences. The spinules are distributed widely throughout the body, similar to C. spinosis, but are simple with a large base (different from that of C. spinosis which has simple as well as bifurcate dermal spindles). They also differ slightly in color. The inside of the mouth, the head, the gill chamber, and the anterior portion of the body are dark brown to black. The dorsal side of the body, and the caudal fin are light brown, and becomes more lightly colored going towards the posterior end. Also, instead of having three or four rows of teeth, C. melanostomus has two rows on both jaws. The general body plan, however, is virtually the same, resembling a tadpole, with a more globular shape in the anterior which tapers in the posterior.[3]

Chaunacops coloratus

The Chaunacops coloratus are another species that were discovered and are known for their bright red and blue colors. It was found that the blue C. coloratus often had an average length of about 110 mm, whereas the red specimen had an average length of 184 mm. It was observed that the specimen begin in a transparent larval form, then become blue, and eventually reach their adult red color. As for predation, it is hypothesized that the specimen turning red is advantageous for ambushing predators that use bioluminescent light to attract possible prey, since the red coloration of this specimen would conceal the predator and make it invisible.[7]

Movement

C. coloratus

Through observations made by an ROV, it was found that the C. coloratus swim vertically with their head oriented upwards. While in rapid ascent, the specimen will use their dorsal, caudal, and anal fins to propel themselves upwards and tuck the rest of their fins in close to their body. The observation collected found that the specimen had average velocities of 0.036 m/s and 0.021 m/s while ascending. As for maneuvering across the ocean floor, observations found that the specimen use their pectoral and pelvic fins. In order to perform this "walking," they use their dorsal fin from one side to side, then thrust their caudal fin repeatedly, and then maneuver using their pectoral and pelvic fins. It was also observed that these specimen are capable of walking backwards using their pectoral and pelvic fins.[7]

Breathing

Fish of the family Chaunacidae have been shown to have slow ventilatory cycles in which the fish exhales 20-30% of their body volume of water. Upon inhalation, Chaunacidae can endure long periods of time maintaining a fully inflated gill chamber, sometimes up to 245 seconds which confers many potential advantages for fish of this family. Chaunacidae have been found to contain a specialized apparatus containing adductor muscles that can maintain its ventilatory cycle, and control the volume of water entering and exiting. These muscles are cross-hatched, and function to not only inhale and exhale, but to prevent any leakage out of the gills.[4]

Due to the high-volume and slow ventilatory cycle, Chaunacidae are able to be majorly energy efficient as it requires less energy to push water across the surface of their gills. Because of this, Chaunacidae are able to go without prey for long periods of time, and remain mostly sedentary.[4]

There are many other hypotheses of advantages conferred by the breathing cycle of Chaunacidae. Due to the long periods of high-volume inhalation, Chaunacidae makes little disturbance of lateral line systems, allowing for better hunting and avoidance of predators. In addition, the maximally filled mouth of the Chaunacidae is often intimidating to predators, making it a defense mechanism that the fish can use much like the Pufferfish.[4]

Diet

Chaunacidae are known to be mostly sedentary fish, and spend most of their time dormant on the seafloor. Because of their energy efficient way of ventilation, Chaunacidae are able to go long periods of time with little food. In a diet study, Chaunax fimbriatus was found to contain a stomach that contained many different prey, showing that Chaunacidae are opportunistic hunters that will eat most anything it can on the seafloor.[4]

Chaunacidae are also steady hunters, as they are able to maintain relatively low movement. Due to their gill chambers, Chaunacidae are able to remain still enough until their prey is within distance.[4]

Taxonomy

Chaunacidae are a family of fish that arise from the order Lophiiformes and of the class Actinopterygii. Chaunacidae contain the genera of both Chaunacops and Chaunax.[3]

Chaunax stigmaeus.

Los gómitas o bostezadores (Chaunacidae) son una familia de peces teleósteos del orden Lophiiformes. Sus especies se distribuyen por los océanos Atlántico, Índico y Pacífico.[1]​ Su nombre procede del griego chaunax, que significa "irrealidad".[2]

Anatomía

Tienen el cuerpo flácido con la capacidad de hincharse en un gran globo; la ruda piel está recubierta de pequeñas escamas similares a espinas; la boca es grande y casi vertical con pequeños dientes dispuestos en bandas en las mandíbulas, en el vómer y en el hueso palatino.[1]

La primera espina de la aleta dorsal simula un cebo que encaja dentro de una depresión sin escamas en forma de U en el hocico, la segunda y tercera espinas de la aleta dorsal invisiblemente incorporadas detrás de la primera; las aletas pélvicas también tienen una espina; las aletas pectorales son similares a un brazo, usándolas como miembros para apoyarse sobre el lecho marino; la abertura de las branquias se dispone por detrás y encima de la base de la aleta pectoral; las líneas laterales tienen canales abiertos, especialmente patentes en la cabeza, protegidos por escamas con agrandadas espinas a ambos lados del canal.[1]

Hábitat

Estas especies son habitantes habituales del talud continental de todos los océanos. Cuando se sienten en peligro se inflan, adquiriendo un enorme tamaño con espinas puntiagudas que disuaden a los depredadores.[1]

Especies

Hay 15 especies válidas, pertenecientes a 2 géneros:[3]

Konnakrotit ( Finnish )

provided by wikipedia FI

Konnakrotit (Chaunacidae) on krottikaloihin kuuluva heimo. Heimon lajeja tavataan kaikista lämpimistä ja lauhkeista valtameristä läheltä rannikkoa.

Lajit ja anatomia

Konnakrottien heimoon kuuluu 2 sukua ja 14 lajia. Lajeja ovat muun muassa konnakrotti (Chaunax fimbriatus) ja rusokonnakrotti (C. pictus). Heimon lajit ovat pienehköjä kaloja, jotka saavuttavat korkeintaan 30–35 cm:n pituuden, yleensä ne jäävät noin 15 cm pitkiksi. Ruumis on muodoltaan pallomainen ja iho on löysä. Suu on hyvin suurikokoinen ja kidusaukko sijaitsee ruumiin takaosassa. Konnakrottilajien ensimmäinen selkäevän ruoto on pidentynyt, mutta ei yhtä pitkä kuin monilla muilla krottikaloilla. Sen kärjessä on bioluminoiva elin. Heimon kalat voivat vetää elimen päässään olevaan onkaloon. Selkäevä on lyhyehkö. Heimon lajien ruumiissa on aistihuokosia, jotka muodostavat avoimen aistikanavasysteemin. Väriltään konnakrottilajit ovat tyypillisesti vaaleanpunaisia tai oransseja ja ruumiissa voi olla vaaleampia keltaisia tai oliivinvihreitä pilkkuja.[1][2][3][4]

Levinneisyys ja elintavat

Konnakrottilajeja tavataan lämpimistä vesistä Atlantista, Intian valtamerestä ja Tyynestämerestä. Ne elävät yksinään lähellä pohjaa mannerjalustoilla 90–2 600 metrin syvyydessä merenpinnasta. Heimon kalat syövät kaloja ja selkärangattomia eläimiä, joita ne houkuttelevat valoelimensä avulla.[1][2][3][4][5]

Chaunacidae ( Italian )

provided by wikipedia IT

I Chaunacidae sono una famiglia di pesci ossei appartenenti all'ordine Lophiiformes.

Distribuzione e habitat

Questa famiglia è distribuita in tutti i mari e gli oceani temperati e tropicali.

Nel mar Mediterraneo sono stati catturati due esemplari, a distanza di quattro anni l'uno dall'altro, della specie Chaunax suttkusi (tipica del mar dei Caraibi e dell'Oceano Atlantico occidentale), nella stessa area tra Sardegna, Sicilia e Tunisia a profondità tra i 500 ed i 600 metri[1][2].

La maggior parte dei Chaunacidae sono specie di profondità quando non abissali che popolano la scarpata continentale.

Descrizione

L'aspetto di questi pesci è stranissimo, il che li rende facilmente riconoscibili: il corpo è quasi sferico è può essere rigonfiato, la bocca è molto grande e in posizione verticale, armata di piccoli ma numerosissimi denti. La pelle è ruvida, cosparsa di piccole scaglie spinose. Il primo raggio della pinna dorsale, così come accade nella rana pescatrice, è staccato dalla pinna e situato sulla fronte del pesce dove costituisce un filamento atto ad attrarre le prede. Le aperture branchiali si aprono sotto l'ascella delle pinne pettorali.

Il colore in genere tende al rosso più o meno vivace.

Si tratta di pesci di modeste dimensioni che solo raramente possono raggiungere i 40 cm.

Biologia

Poco nota.

Alimentazione

Si cibano di altri pesci.

Chaunax stigmaeus

Chaunacidae är en familj av marulkartade fiskar (Lophiiformes) som lever i djuphavet.[1]

De är bottenlevande och förekommer på kontinentalbranten i Atlanten, Indiska Oceanen och Stilla Havet.[2] på djup upp till åtminstone 2460 m. Av familjens två släkten förekommer Chaunacops typiskt på större djup än Chaunax, men överlappningen är stor.

De har stora klotformiga kroppar, en kort sammantryckt stjärt och täcks av små taggiga fjäll. Deras främsta ryggfena är modifierad till ett kort "metspö" med ett bioluminiscent bete i spetsen, som dinglar över den uppåtvända, nästan vertikala, munnen vars tänder är små. Sidolinjens kanaler är påfallande tydliga.[3] De är mellan 7 och 40 cm långa och skära till djupt orangeröda.

Systematik

Familjen delas in i två släkten med sammanlagt 16 arter.

Хаунаксовые ( Russian )

provided by wikipedia русскую Википедию

В состав семейства включают два рода с 22 видами[3]:

Описание

Тело шарообразное, слегка сжато с боков, покрыто свисающей мягкой кожей. Кожа густо покрыта мелкими чешуйками в форме колючек, напоминающими по форме и на ощупь плакоидную чешую некоторых видов акул. Первый спинной плавник представлен только коротким иллицием с мочалообразной эской (лат. esca) на конце, других колючих лучей нет. Иллиций расположен сразу за ртом на яйцевидном участке кожи без чешуи или в углублении, в который он может убираться. Эска с многочисленными короткими, плотно сидящими нитями. Во втором спинном плавнике 10—12 мягких лучей. Грудные плавники узкие, веслообразные, с 10—15 мягкими лучами. В анальном плавнике 5—7 мягких лучей. Хвостовой плавник закруглённый[4] .

Голова очень большая, немного кубовидная с хорошо выраженными открытыми латеральными каналами. Глаза расположены по бокам головы в верхней части и прикрыты кожей. Рот крупный от косого до почти вертикального с небольшими тонкими зубами. Открытый канал боковой линии проходит вдоль всего тела до хвостового стебля, хорошо заметные сенсорные каналы также имеются на голове и брюхе. Количество невромастов боковой линии является родовым и видовым признаком[4].

Окраска тела от розовой до красновато-оранжевой. У некоторых видов по телу разбросаны бледные или жёлтые пятна.

フサアンコウ科 Chaunax stigmaeus.jpg
フサアンコウ属の1種 Chaunax stigmaeus
分類 : 動物界 Animalia : 脊索動物門 Chordata 亜門 : 脊椎動物亜門 Vertebrata : 条鰭綱 Actinopterygii 亜綱 : 新鰭亜綱 Neopterygii 上目 : 棘鰭上目[1] Acanthopterygii : アンコウ目 Lophiiformes 亜目 : フサアンコウ亜目 Chaunacoidei : フサアンコウ科 Chaunacidae 英名 Coffinfishes, Sea toads 下位分類 本文参照

フサアンコウ科学名Chaunacidae)は、アンコウ目に所属する魚類の分類群()の一つ。ミドリフサアンコウなど、底生性深海魚を中心に2属22種が含まれる[1]

分布・生態[編集]

フサアンコウ科の魚類はすべて海水魚で、太平洋インド洋大西洋など世界中の深海に幅広く分布する[1]。水深90mから2,000mにかけての大陸斜面海山を主な生息範囲とし[1]、日本近海からは少なくとも1属3種が報告されている[2][3][4]

特徴的なずんぐりした体型は遊泳には不向きで、岩礁および砂泥の海底でじっとしている姿がしばしば観察される[2][3]。誘引突起を利用した待ち伏せ型の捕食を行うとみられるが[3]、その他の生活史についてはほとんどわかっていない。日本では底引き網延縄によって漁獲され、味醂干し鍋料理などに利用される[3]

形態[編集]

 src=
フサアンコウ属の1種(Chaunax pictus)。風船のような丸い体と細長い尾柄部が本科魚類の特徴である

丸みを帯びた球状の体型をもち、皮膚は風船のようにぶよぶよとして柔軟性が高い[5]。ピンクやオレンジ、あるいは赤色を基調とした体色の種が多く、体長は最大種で35cmほどになる[1]。体表はトゲ状あるいは細長い糸状の突起によって覆われる[5]。口は斜め上向きでほとんど垂直となり、顎・鋤骨口蓋骨に微小な歯を備える[5]

アンコウ目の魚類に共通した特徴として、背鰭の第1棘条に由来する誘引突起をもつが、他の棘条は欠いている[1]。頭部にはU字状のくぼみが存在し、誘引突起および擬餌状体を収納することができる[5]。背鰭および臀鰭の軟条はそれぞれ10-12本・5-7本で、腹鰭は小さく1棘4軟条からなる[5]。胸鰭はやや大きく腕のような形状をもつが[5]、近縁のアカグツ科ほどには発達していない。の開口部は胸鰭基底の後方に位置する[1]

分類[編集]

フサアンコウ科は単独でフサアンコウ亜目 Chaunacoidei を構成し、Nelson(2016)の体系において2属22種が認められている[1]カエルアンコウなどを含むカエルアンコウ亜目の仲間から本科を経て、アカグツ科(アカグツ亜目)へと形態の特化が進んだものとみられている[6]
