Abbottina rivularis (Chinese false gudgeon or Amur false gudgeon) is a species of ray-finned fish in the family Cyprinidae, the carps and minnows. It is native to China, Korea, and Japan. It has been introduced to the Mekong River Basin and it is also known from rivers in Turkmenistan.Froese, R. and D. Pauly. (Eds.) Abbottina rivularis. FishBase. 2011. This species is mature at about 4 or 5 centimeters in length, and the maximum recorded length was 18.9 centimeters. It has eight dark spots along its lateral line and many black dots on its caudal fin. This freshwater fish lives in rivers and lakes, and it is often found in converted lowland aquatic habitat, such as irrigation ditches and ponds associated with rice paddies.Hayashi, K., et al. (2013). Growth and habitat use of the Chinese false gudgeon, Abbottina rivularis, in an irrigation channel near the Ushizu River, northern Kyushu Island, Japan. Ichthyological Research 60, 218-26. This fish is host to a number of recorded parasites, including the monogenean flatworms Gyrodactylus rivularae and G. gobioninum,You, P., et al. (2011). Gyrodactylus rivularae n. sp.(Monogenoidea: Gyrodactylidae) from Abbottina rivularis (Basilewsky, 1855) (Pisces: Cyprinidae) in Central China.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Abbottina rivularis has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
Besides the big genome in the nucleus, cells carry a small, circular loop of DNA inside the cell's energy factories — the mitochondria. It is inherited almost only from the mother and is a leftover from ancient bacteria that moved into the cell. The mitochondrial markers above (ND*, COX, CYTB…) are read from exactly this loop. Outer ring = one strand, inner ring = the other.
The complete instruction manual Abbottina rivularis carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Where the DNA of Abbottina rivularis was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
Modelled climatemodelled
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
