Skeleton of the anglerfish Lophius piscatorius: The first spine of the dorsal fin of the anglerfish acts as a fishing rod with a lure. The name "anglerfish" derives from the species' characteristic method of predation. Anglerfish typically have at least one long filament sprouting from the middle of their heads, termed the illicium.
Skeleton at the Muséum de Toulouse. The fish has long filaments along the middle of its head, which are, in fact, the detached and modified three first spines of the anterior dorsal fin. The filament most important to the angler is the first, which is the longest, terminates in a lappet, and is movable in every direction.
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology , which is the study of how the component parts of fish function together in the living fish. [ 1 ]
Lophius was first proposed as a genus by Carl Linnaeus when he described Lophius piscatorius in the 10th edition of Systema Naturae given as "in Oceano Europæo", meaning the Northeastern Atlantic Ocean, Mediterranean and Black Seas with localities mentioned including Bordeaux, Marseille and Montpellier in France; Genoa, Rome, Naples and Venice in Italy; Lesbos in Greece; and Syria.
Actinopterygii (/ ˌ æ k t ɪ n ɒ p t ə ˈ r ɪ dʒ i aɪ /; from Ancient Greek ἀκτίς (aktis) 'having rays' and πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish [2] that comprise over 50% of living vertebrate species. [3]
Unlike most other deepsea anglerfish, H. mollis lacks pigmentation, and both sexes appear pallid and translucent, with the musculature and portions of the skeleton clearly showing through the skin. Free-living males only grow to about 2 cm (0.8 in), and differ from the adult and juvenile females by the noticeable lack of a short, bubble-like ...
Ceratioidei, the deep-sea anglerfishes or pelagic anglerfishes, is a suborder of marine ray-finned fishes, one of four suborders in the order Lophiiformes, the anglerfishes.
Fish bone is any bony tissue in a fish, although in common usage the term refers specifically to delicate parts of the non-vertebral skeleton of such as ribs, fin spines and intramuscular bones. Not all fish have fish bones in this sense; for instance, eels and anglerfish do not possess bones other than the cranium and the vertebrae.
