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.
A closeup of the skin on an Eldon's galaxias. The slime coat (also fish slime, mucus layer or slime layer) is the coating of mucus covering the body of all fish.An important part of fish anatomy, it serves many functions, depending on species, ranging from locomotion, care and feeding of offspring, to resistance against diseases and parasites.
The white handle of this tantō (left) is covered with shagreen in its natural form. Two small decorative elephants made of silver and shagreen. Shagreen has an unusually rough and granular surface, and is sometimes used as a fancy leather for book bindings, pocketbooks and small cases, as well as its more utilitarian uses in the hilts and scabbards of swords and daggers, where slipperiness is ...
In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopterans ( butterflies and moths ), scales are plates on the surface of the insect wing , and provide coloration.
They have been seen to have the ability to assess their surroundings and match the color, contrast and texture of the substrate even in nearly total darkness. [58] The color variations in the mimicked substrate and animal skin are similar. Depending on the species, the skin of cuttlefish responds to substrate changes in distinctive ways.
They are a silvery color and have a rough skin texture. The mola is the heaviest of all the bony fish, with large specimens reaching 14 ft (4.3 m) vertically and 10 ft (3.0 m) horizontally, and weighing over 6,000 lb (2,700 kg). [3] Sharks and rays can be heavier, but they are cartilaginous fish.
Many fishermen prefer to fillet with an electric knife, first removing the fillet from along the backbone, and then using the electric knife to cut the fillet from the skin and scales. Fish over 15 pounds (6.8 kg) can become tough and have a consistency comparable with chicken, rather than the flakey texture of many species of fish.
Their unusual shape, colour, and skin textures disguise frogfish. Some resemble stones or coral, while others imitate sponges or sea squirts with dark splotches instead of holes. In 2005, a species was discovered, the striated frogfish, that mimics a sea urchin, while the sargassumfish is coloured to blend in with the surrounding sargassum. [13]
