The fish are mostly found in the Atlantic, Indian, and Pacific Oceans, although the species Cyclothone microdon may be found in Arctic waters. They have elongated bodies from 2 to 30 cm (0.79 to 11.81 in) in length. [2] They have a number of green or red light-producing photophores aligned along the undersides of their heads or bodies. [1]
The mouths of these fish are most commonly located on the underside of their head (subterminal), with thick, fleshy lips.Most species are less than 60 cm (2.0 ft) in length, but the largest species (Ictiobus and Myxocyprinus) can surpass 100 cm (3.3 ft).
The Amazon molly shares many of the same general characteristics of its parent species. Some of these characteristics include a rounded caudal fin, a small anal fin, small pelvic fins, pectoral fins located just behind the operculum, a small terminal mouth, and a compressed body shape.
Hagfish embryos have characteristics of gnathostomes and may be plesiomorphic; [33] however, these characteristics drastically change morphologically as the hagfish matures. [33] The following hagfish and lamprey phylogeny is an adaptation based on the 2019 work of Miyashita et al. [ 69 ]
Lanternfish themselves have been found to feed on bits of plastic debris accumulating in the oceans. [8] At least one lanternfish was found with over 80 pieces of plastic chips in its gut, according to scientists monitoring ocean plastic in the Pacific Ocean's eastern garbage patch. [9]
Herring are various species of forage fish, belonging to the order Clupeiformes.. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America.
Generally shallow-water fish, tilefish are usually found at depths of 50–200 m in both temperate and tropical waters of the Atlantic, Pacific, and Indian Oceans. All species seek shelter in self-made burrows, caves at the bases of reefs, or piles of rock, often in canyons or at the edges of steep slopes. Either gravelly or sandy substrate may ...
Yet only one species, the burbot (Lota lota), is a true freshwater fish. [2] Common characteristics include the positioning of the pelvic fins (if present), below or in front of the pectoral fins. Gadiformes are physoclists, which means their swim bladders do not have a pneumatic duct. The fins are spineless.
