Isinglass (/ ˈ aɪ z ɪ ŋ ɡ l æ s,-ɡ l ɑː s / EYE-zing-gla(h)ss) is a form of collagen obtained from the dried swim bladders of fish. The English word origin is from the obsolete Dutch huizenblaas – huizen is a kind of sturgeon , and blaas is a bladder, [ 1 ] or German Hausenblase , meaning essentially the same. [ 2 ]
Cosmine was first described in the Osteolepiform Megalichthys hibberti by Williamson in 1849, in a purely descriptive, pre-Darwinian, non-evolutionary framework. [4] Goodrich [5] expanded on Williamson's descriptions, hypothesizing a transition from a monoodontode scale (like a chondryicthian placoid scale) to a complex polyodontode scale through fusion of discrete units.
Collagen is also abundant in corneas, blood vessels, the gut, intervertebral discs, and the dentin in teeth. [3] In muscle tissue, it serves as a major component of the endomysium. Collagen constitutes 1% to 2% of muscle tissue and 6% by weight of skeletal muscle. [4] The fibroblast is the most common cell creating collagen in animals.
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages.
The diet of the arapaima consists of fish, crustaceans, fruits, seeds, insects, and small land animals that walk near the shore. [18] The fish is an air breather, using its labyrinth organ, which is rich in blood vessels and opens into the fish's mouth, [19] an advantage in oxygen-deprived water that is often found in the Amazon River.
A urokotori (うろこ取り, scale remover) is a utensil used in Japanese cuisine to remove the scales from the skin of fish before cooking. [ 1 ] [ 2 ] Although it is possible to remove the scales with a knife, this is more difficult and there is a higher risk of cutting the skin of the fish, especially with small fishes; knife-scaling also ...
The mineral texture of alligator gar scales consists of bundles of cross-plied hydroxyapatite minerals oriented towards the scale's surface. Ganoine or ganoin is a glassy, often multi-layered mineralized tissue that covers the scales , cranial bones and fin rays in some non-teleost ray-finned fishes , [ 1 ] such as gars and bichirs , as well as ...
In biology, the extracellular matrix (ECM), [1] [2] also called intercellular matrix (ICM), is a network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells.
