Cat coat genetics basic pattern of stripes that underlies the coat. The basic wild-type tabby gene, "Mc", produces what is called a "mackerel striped" tabby (stripes look like thin fishbones and may break up into bars or spots), while a recessive mutant, "mc", produces a blotched or "classic" tabby pattern (broad bands, whorls, and spirals of dark color on pale background usually with bulls-eye or oyster pattern on flank). The classic tabby is most common in Iran, Great Britain and in lands that were once part of the British Empire and Persian Empire. The gene responsible for this differential patterning has been identified
Blue mackerel stay in areas within a few degrees of in tropical to subtropical waters. Off the east coast of North America, populations of mackerel have grown to over 2 million after being depleted in 1982. Blue mackerels can be found from the coast of North America, and as far as Australia and Japan. The blue mackerel is known as a voracious and indiscriminate carnivore, devouring microscopic plankton, krill, anchovies, and dead cut bait, and striking readily on lures and other flies. When in a school and in a feeding frenzy, blue mackerel will strike at nonfood items such as cigarette butts
