Koi
The major named varieties include:Goldfish (金魚) were developed in China more than a thousand years ago by selectively breeding Prussian carp for color mutations. By the Song dynasty (960–1279), yellow, orange, white, and red-and-white colorations had been developed. Goldfish ("Carassius auratus") and Prussian carp ("Carassius gibelio") are now considered different species. Goldfish were introduced to Japan in the 16th century and to Europe in the 17th century. Koi, though, were developed from common carp in Japan in the 1820s. Koi are domesticated common carp ("Cyprinus carpio") that are selected or culled for color; they are not a different species, but a subspecies, and will revert to the original coloration within a few generations if allowed to breed freely.
Common greenshank
The common greenshank ("Tringa nebularia") is a wader in the large family Scolopacidae, the typical waders. The genus name "Tringa" is the New Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek "trungas", a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific "nebularia" is from Latin "nebula" "mist". Like the Norwegian "Skoddefoll", this refers to the greenshank's damp marshy habitat.
