From some vantage points the carapaces seem soft as feathers, from other spots they resemble a daunting layer of scales.
The skin forms a cover, often with an outer layer of scales, and secretes a slimy mucus, which lubricates the fish and seals the surface.
Removal of the outer layer of scales at this time point resulted in oxygenation of the outer 15 1800 µm of the tissue profile, relative to the intact bud, although the core remained near 2·5 kPa (Fig. 3B).
Over time, thick layers of scale, metal stains, bacteria, mold, and mildew can build up in your tank if you're not cleaning it properly.
The scale-space distribution problem is addressed by assigning an appropriate number of point features to each scale layer of each scale-space octave.
I think what really happens is that experience painfully rips away layers of scales from our eyes, and so we do indeed become more cynical about many of the things we naively accepted when younger.
Scale insects, unless parasitized, produce enormous populations on green twigs, young limbs, leaves, and fruit; when tree bark or shrubs become encrusted with one or more layers of scales, the entire plant often dies.
Using scanning electron microscopy to see the peacock spider's design up close, researchers discovered that tiny threadlike fibers sandwiched in between two layers of scales coat the spider's exterior a design unique to this spider.
The cuticle consists of overlapping layers of scales, each about 0.5 μm thick and is composed of β keratin.
