Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
In the production of photographic prints, spotting is a type of retouching flaws in the finished print with specially made paints, dyes, pencils and pens. [1] White spots on gelatin-silver prints made from negatives are caused by dust adhering to the negative or paper during exposure. Prints from positive transparencies exhibit black marks.
Ornithonyssus bacoti (also known as the tropical rat mite and formerly called Liponyssus bacoti) is a hematophagous parasite. [1] It feeds on blood and serum from many hosts. [2] [3] O. bacoti can be found and cause disease on rats and wild rodents most commonly, but also small mammals and humans when other hosts are scarce.
Nummular eczema, also called discoid eczema, is a type of eczema rash that shows up in a distinctive round pattern. The rashes may be itchy, red and raised ovals, the AAD says, and there may be ...
Tetrachromacy is demonstrated among several species of birds, [2] fishes, [3] and reptiles. [3] The common ancestor of all vertebrates was a tetrachromat, but a common ancestor of mammals lost two of its four kinds of cone cell, evolving dichromacy, a loss ascribed to the conjectured nocturnal bottleneck. Some primates then later evolved a ...
Echimyidae is the family [2] of neotropical spiny rats and their fossil relatives. [3] This is the most species-rich family of hystricognath rodents. [ 4 ] It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. [ 4 ]
The larvae, commonly called chiggers, are about 170–210 μm (0.007–0.008 in) in diameter, normally light red in color, and covered in hairs; they move quickly relative to size. The larvae congregate in groups on small clods of soil, in matted vegetation, and even on low bushes and plants, where they have more access to prospective hosts.
Step Three: Remove Streaks. Combine one part vinegar and one part water in a bowl. Dampen a clean microfiber cloth with the mixture and apply it to the glass, wiping it down well for a streak-free ...
