Dermal structures giving support and protection to the body and properly considered as an exoskeleton.Scales are reduced or lacking in some fishes.Scales types include placoid scales (dermal denticles) of sharks; ganoid scales, which are very thick and hard and are arranged like paving blocks with very little overlap; cycloid scales which are thin and overlap like shingles (imbricated); and ctenoid scales which are like the cycloid type but have many tiny teeth or spines on the exposed surface.
Aggregate of small, flattened, overlapping crystals, as seen in fish scales.
thin, overlapping plates of a hard substance that protect the skin of fish. The easiest way to tell if a fish has scales is to run your finger along the side of the fish from back to front. If the fish feels smooth and slippery, it has no scales or the scales are embedded within the skin; if it feels rough and your finger catches, then it has external scales.
Thin, small, overlapping plates which protect the salmon's body. Scales grow in regular concentric patterns and can be used to determine the age and life history of a salmon
Also known as cuticle. The outer layer of cells of mammal hair fiber which are hard, flattened, do not fit together evenly and whose surfaces overlap and enclose the cortex. The size and shape vary from species to species and are important characteristics used in fiber identification. The exposed edges of scales point towards the tips of animal fibers and give rise to the friction effect and felting.
The shingle-like plates covering the wings of a butterfly that give it its colour and pattern.
Thin, overlapping flat plates that form a protective outer covering on fish, reptiles, and the legs of birds.
Wings of Lepidoptera are normally covered with rows of overlapping scales. Scales occur in a number of different types: forked, hair-like, imbricate, spatulate, or strap-like.
Thin, small, overlapping plates which protect a fish's body. Scales grow in regular concentric patterns and can be used to determine the age and life history of a fish.
The defining anatomical structures of Order Lepidoptera. Scales are tiny modified bristles covering most of the body surface. Most scales of the wings are flattened and overlapping, resembling in miniature the shingles on the roof of a house. Scales contain the molecules (pigments) that provide much of the color of the lepidopteran wings. Some wing colors are produced by the interplay of light with microscopic structures of scales, rather than involving pigments.
The millions of modified hairs forming shingle-like plates covering moths' and butterflies' wings
(noun) - tiny modified hairs which overlap on a butterfly wing. The scales give the butterfly wings their color and beauty.
These are tiny three-dimensional structures which are found on the wings of butterflies and moths. In some cases, the brilliant colors of Neotropical butterflies are created entirely by scales and the way in which they refract light differently.
a bony outer covering of reptiles
Protective plates that cover a reptiles body.
Thin, flat, hard plates that cover a fish.
These are the protection for the body of the fish. They are composed of connective tissue covered with calcium. They are only developed during the first year of life and get progressively larger. They are mostly arranged like tiles on a roof. Scales can be used for discovering the age of a fish.
Outermost portion of the cuticle, flattened and imbricate in humans, pointing toward the distal end of the hair shaft.
The small, hard, overlapping plates covering a chicken's shanks and toes.
covering of fish composed of dead material similar in substance to that which composes our fingernails; can be either cycloid (with smooth rear edges) or ctenoid (with serrated rear edges) in bony fishes
