Phosichthyidae
Lightfishes are small stomiiform fishes in the family Phosichthyidae The earliest fossils of lightfishes are of the genus †'' Sytchevskia'' Prokofiev, 2002, known from Middle Eocene-aged Tethyan marine strata in Georgia. They are very small fishes found in oceans throughout the world: most species grow no longer than 10 cm, while those in the genus '' Vinciguerria'' only reach 4 cm or so. They make up for their small size with abundant numbers: '' Vinciguerria'' is thought — with the possible exception of '' Cyclothone'' — to be the most abundant genus of vertebrates. Deep-sea trawls of the Humboldt Current in the southeast Pacific have found that lightfishes make up 85% by mass of mesopelagic fishes, with '' Vinciguerria lucetia'' by far the most numerous species. They are bioluminescent fishes, possessing rows of photophores along their sides, with which they hunt planktonic invertebrates, especially krill, copepod Copepods (; meaning 'oar-feet') are ...

Stomiiform
Stomiiformes is an order of deep-sea ray-finned fishes of very diverse morphology. It includes, for example, dragonfishes, lightfishes (Gonostomatidae and Phosichthyidae), loosejaws, marine hatchetfishes and viperfishes. The order contains 4 families (5 according to some authors) with more than 50 genera and at least 410 species. As usual for deep-sea fishes, there are few common names for species of the order, but the Stomiiformes as a whole are often called dragonfishes and allies or simply stomiiforms. The scientific name means "''Stomias''-shaped", from ''Stomias'' (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek ''stóma'' (στόμᾶ, "mouth") + Latin ''forma'' ("external form"), the former in reference to the huge mouth opening of these fishes. The earliest stomiiform is ''Paravinciguerria'' from the Cenomanian of Morocco and Italy. Description and ecology Members of this order are mostly pelagic fishes living in dee ...

Photophore
A photophore is a specialized anatomical structure found in a variety of organisms that emits light through the process of boluminescence. This light may be produced endogenously by the organism itself (symbiotic) or generated through a mutualistic relationship with bioluminescent bacteria (non-symbiotic), resulting in light production on a glandular organ of animals. Light organs are most commonly found in marine animals, including many species of fish and cephalopods. The organ can be simple, or as complex as the human eye, equipped with lenses, shutters, color filters, and reflectors; unlike an eye, however, it is optimized to produce light, not absorb it. In the context of developmental biology, light organs form through precise genetic regulation and, in some cases, microbial colonization during specific stages of an organism's life cycle. They play a crucial evolutionary role in enabling species to adapt to low-light or dark environments, particularly in the deep sea. ...

Amphipod
Amphipoda () is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods () range in size from and are mostly detritivores or scavengers. There are more than 10,700 amphipod species currently recognized. They are mostly marine animals, but are found in almost all aquatic environments. Some 2,250 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator'' and '' Arcitalitrus sylvaticus''. Etymology and names The name ''Amphipoda'' comes, via Neo-Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and ...
