The feisty fairy wrasses turned to a neon kaleidoscope all thanks to a coral reef species pump. Fairy wrasses are swimming jewels, dancing, and flouncing around coral reefs.
The finger-length fishes arrogant, vibrant courtship exhibitions are meant for mates and competitors, and a recent study proposes that the gentle waxing and waning of ice sheets glaciers and ice sheets may be partially accountable for such a variety of performances.

Colorful Reef Fishes
Scientists reported on the 23rd of February in Systematic Biology that a recent genetic analysis of over three dozen fairy wrasse species details the approximately 12 million years of evolution that created their wide assortment of colors, shapes, and behaviors. And the schedule of these transformations means that over 60 species of fairy wrasses may owe their great diversity to cyclic sea-level alteration over the previous few millions of years.

A Japanese fish named Hanako is thought to be the longest-serving Koi fish in history, having made it to the glorious old age of 226 before she died in 1977. The scarlet-colored fish was born in 1751, Japan, in the heart of the Tokugawa era.
While the typical lifespan of a scarlet koi carp is about 40 years, Hanako endured to live competently into the 1970s and was 226 years old when she died. Her remarkable story was initially communicated when her last owner Dr. Komei Koshihara made a national report on Nippon Hoso Kyokai radio station in 1966.

Hanako s Age
Koshihara said he realized Hanako s age because he had it analyzed by professor Masayoshi Hiro, who operated at the Animal Science Laboratory at Women s College, Nagoya. Pair of the fish s scales had been pulled and examined for more than two months, enabling Hiro to figure the rings of growth on her scales to assume her age.
