![Male deep-sea anglerfish. Common among deep-sea anglerfish is the strong sexual dimorphism in melanocetids: while females may reach a length of 18 centimetres or more, males remain under 3 centimetres. After a larval and adolescent free-living stage, they spend the rest of their life parasitically attached to a female. [size of single organism: 20 cm] | Tiefseeanglerfische männchen. Dieses ca. 2 cm große Exemplar gehört zu der Gruppe der Tiefseeanglerfische. Es gibt einen starken sexuellen Dimorphismus. Während Weibchen eine Länge von 18 oder mehr Zentimeter erreichen können, bleiben Männchen bei Längen von unter drei Zentimetern. Nach der Metamorphose von der Fischlarve in das adulte Tier beginnt das Männchen mit Hilfe seiner Augen und des gut ausgebildeten Geruchssinnes ein Weibchen zu finden. Hat es eines erreicht, beißt es sich an diesem fest, die Kiefer des Männchens bilden sich danach zurück und die Haut beider Tiere verwächst, ebenso die Blutgefäße. Bis auf die Kiemen werden alle Organsysteme reduziert und die Ernährung erfolgt anschließend nur noch über den Blutkreislauf des Weibchens.](https://m.psecn.photoshelter.com/img-get2/I0000fO4STMVyA7A/fill=/fit=180x180/I0000fO4STMVyA7A.jpg)

Although this is not true bioluminescence, light is emitted from these same photophores. The glow is directed downward through light-guides, presumably to function as effective counterillumination seen only from below.

Während der Nacht steigt er aber in flachere Wasserschichten bis 100 m unter der Wasseroberfläche auf. Als Anpassung an dieses Leben in der Dämmerlichtzone hat der Beilfisch große Augen und an der Bauchseite eine Reihe von Leuchtorganen. Das bläuliche Licht an seiner Unterseite tarnt den Beilfisch, wenn Räuber von unten gegen das schwache Licht der fernen Oberfläche nach Beute suchen.](https://m.psecn.photoshelter.com/img-get2/I0000UMFa9QDQmm4/fill=/fit=180x180/I0000UMFa9QDQmm4.jpg)

![Female Toothed seadevil (Neoceratias spinifer) with male attached. Sexual Parasitism in Ceratioid Anglerfishes.In some ceratioid taxa, the male's attachment to the female is followed by fusion of epidermal and dermal tissues and, eventually, by a connection of the circulatory systems so that the male becomes permanently dependent on the female for blood-transported nutrients, while the host female becomes a kind of self-fertilizing hermaphrodite. Neoceratiidae (subclass Actinopterygii, order Lophiiformes) A monospecific family (Neoceratias spinifer) of small (6 cm long), deep-sea fish that have a large head, a large mouth, and small eyes. The jaws are equipped with many long and slender teeth. The single dorsal, caudal, and anal fins have a rounded profile, while the pectorals are small. No illicium is present. Females are larger than males; males may form a parasitic relationship with their female sex partners. They are found in all oceans.. Permanent attachment is usually accomplished by means of separate outgrowths from the snout and tip of the lower jaw of the male, both of which eventually fuse with the skin of the female. In some species a papilla of female tissue protrudes into the mouth of the male, sometimes appearing to completely occlude the pharynx. The heads of some males become broadly fused to the skin of the female, extending from the tip of the lower jaw to the rear of the skull, appearing as if embedded or absorbed by their mate, while in others, the male is carried at the tip of an elongate, cylindrical stalk of female tissue. ..Increasing considerably in size once fused, their volume becoming much greater than free-living males of the same species, and being otherwise completely unable to acquire nutrients on their own, the males are considered to be parasites.

![Deep sea Pram Bug Phronima. amphipod (Phronima sp.) with young in a salp house. Phronima, the pram bug amphipod, is a small, translucent deep-sea hyperiid amphipod of the family Phronimidae. It resembles a shrimp with a head, eyes, jaws and clawed arms. Phronima are only seen in the wild at great depths. Phronima are carnivorous; they eat small plankton. P. sedentaria often uses dead salps for housing. Phronima served as an inspiration for the design of the Xenomorphs of the Alien film series. housing young within salp [size of single organism: 2,5 cm] | Dieser winzige Tiefsee-Krebs (Phronima sp) war die Vorlage für die Titel-Figur aus Ridley Scotts Kultfilm "Alien".

![Phronima, the pram bug amphipod, is a small, translucent deep-sea hyperiid amphipod of the family Phronimidae. It resembles a shrimp with a head, eyes, jaws and clawed arms. Phronima are only seen in the wild at great depths, usually by submarine crews, and are usually only about 2.5 cm (1 inch) long. Phronima are carnivorous; they eat small plankton. <br />
<br />
The eyes of the adult Phronima are a further feature of wonder in an animal already beset with extraordinary habits and adaptations. It has compound eyes, like most crustacea and insects, but unlike most it has four, not two. Each pair of eyes is situated on the side of the head. The outer and inner eye of each pair are actually in contact with each other. The outer eye is surrounded by a lozenge-shaped ball of eye-facet lenses commanding an enormous field of view - perhaps 270 degrees. One pair of eyes keeps a constant watch on the world ahead, whereas the other pair views the surroundings through the transparent walls of its temporary home. <br />

![Melanocetus murrayi is a fish that has several English names: black deep-sea angler, Murray’s abyssal anglerfish or deepsea blackdevil . It usually lives at depths between 1000 and 2500 m, but has also been found more than 6000 m below the surface. This anglerfish is distributed in all oceans to latitudes of 65°. The typical feature of anglerfishes is a fleshy process near the mouth with bioluminescence bacteria. This is used as a lure to attract prey in the dark of the deep sea.

![The deep sea viperfish (Chauliodus sloani) is approx. 30 cm long and lives within the upper 1000 m of the water column. During day they prefer deeper water layers while they actively ascend at night. Their numerous light emitting organs help on the one hand to attract prey, on the other hand they serve as a camouflage when seen from below against the light coming in from the surface. Its enormous teeth enable the viperfish to securely grab its prey. This is essential as in the deep sea encounters are very rare and each chance has to be taken. However, if the viperfish bites a prey item that is too big to be swallowed, the inward-bent teeth make it impossible to let go, which may well mean the end to both parties involved.

![This deep sea amphipod genus is particularly renowned for its house-building. This transparent organism feeds upon free-living, planktonic sea squirts and salps. It devours the internal soft body parts of its live prey and is then left surrounded by a tough, transparent husk of tunicin. It is this outer casing that it then modifies to form an open-ended barrel, the final shape of which is particular to the species of Phronima and the salp in question. This macabre activity seems to be conducted by the female amphipods, and in time eggs or hatchlings are deposited as a saddle on the inner wall of the barrel. Here they remain and grow, aerated by a constant flow of water that moves through the barrel as the female swims through the water column. With advancing age comes the spirit of adventure and juveniles start to stray from their brood site towards the margins of the barrel.

[size of single organism: 6 cm] | Schwarzer Drachenfisch.Malacosteus niger.Stoplight loosejaw.09.05.1991.RMT8 600-400.0 - 2500 m..Der Schwarze Drachenfisch ernährt sich hauptsächlich von Copepoden .(kleinen Krebsen). Als einer der wenigen Tiefseefische kann er rotes .Licht aussenden und auch sehen. Wie das geschieht, wurde erst .kürzlich erforscht..Malacosteus niger kann mit Hilfe von rotem Scheinwerferlicht seine.Beute sehen, ohne dass er selber gesehen werden kann, und ohne dass.andere Raubfische angelockt werden. .Die Photozellen produzieren zunächst blaugrünes Licht, das von .Pigmenten wieder absorbiert wird und mit 626 nm den Filter erreicht. .Dort wird es nochmal gefiltert, und schliesslich mit 705 nm ins Meer .ausgesandt..Malacosteus niger hat nicht wie wir Sehpigmente, die für rotes Licht.empfindlich sind. Das rote Licht wird zunächt von einem speziellen .Antennenpigment absorbiert und in Form von Energie den Sehzellen .zugeführt. Dort können die auf blaues und grünes Licht empfindlichen .Sehpigmente die Information weiterleiten. Das Antennenpigment ist dem .Chlorophyll der grünen Pflanzen ähnlich und verwandelt wie .pflanzliches Chlorophyll Licht in Energie.](https://m.psecn.photoshelter.com/img-get2/I0000NCnjvbD7hBY/fill=/fit=180x180/I0000NCnjvbD7hBY.jpg)
