Diverse pigment patterns of species closely related to zebrafish |
|
Danios comprise at least 35–50 species and are native to India, Myanmar, Thailand, Vietnam and elsewhere in east Asia. The traditional grouping "danio" has been split into different genera, Danio and Devario. Shown is our phylogeny for some of these species, derived from maximum likelihood and Bayesian analyses of 12S and 16S rDNA sequences (Quigley et al. 2004, Quigley et al. 2005). Both Danio and Devario include species with horizontal stripes, vertical bars, and uniform patterns, offering an outstanding opportunity to examine rapid and repeated evolutionary changes in pigment pattern. Below we provide examples of some of these species. Since some species go by several sometimes conflicting common and scientific names, we also provide links to 12S and 16S rDNA sequences that we have deposited in Genbank from the species shown in the accompanying images. If using these sequences in phylogeny reconstruction, please cite support from NSF IOB-0444517 to D. Parichy. Thanks!

Genbank GI |
| Danio albolineatus |  |
almost uniformly dispersed melanophores, xanthophores, iridophores and erythrophores
|
||
| Danio aff. albolineatus |  |
similar to D. albolineatus, less distinct stripe of iridophores; possibly D. roseus | ||
| Danio kerri |  |
few, wide stripes |
|
|
| Danio "hikari" |  |
few, wide stripes; species not formally described; sold commercially as "danio hikari"; green variety are males and blue variety are females |
||
| Danio aff. kyathit |  |
stripes are added by fission of existing stripes, in contrast to D. rerio; erythrophores present, also unlike D. rerio |
||
| Danio kyathit |  |
large spots grading into stripes | coming soon |
|
| Danio rerio |  |
several disinct stripes of melanophores and xanthophores |
||
| Danio nigrofasciatus |  |
stripes and spots; stripes develop differently from zebrafish with persisting melanophores from embryonic stages; sold commercially as "dwarf danio" or "spotted danio" |
||
| Danio "burma" |  |
spots; body size similar to D. nigrofasciatus; sold commercially as the Burma danio | coming soon |
|
| Danio choprae |  |
initially horizontal stripes with vertical bars developing later; abundant red erythrophores |
||
| Danio dangila |  |
light spots and wavy stripes; much larger than other species in Danio |
||
| Danio meghalayensis |  |
large danio, broken stripes; abundant erythrophores in fins | coming soon |
|
| Danio feegradei |  |
iridophore spots on dark background; sold commerically as "danio gold laser", "Rakhine danio" and Danio freegradei | coming soon
|
|
| Devario shanensis |  |
vertical bars; a relatively small species within Devario |
||
| Devario devario |  |
broken and irregular vertical bars | ||
| Devario aequipinnatus |  |
relatively diffuse horizontal stripes; sold commercially as "giant danio" | ||
| Devario assamensis |  |
diffuse horizontal stripes | coming soon |
|
| Devario acuticephala |  |
uniform pattern | coming soon |
|
| Danionella translucida |  |
larval like pigment pattern and morphology even in the adult (pictured here) | coming soon
|
|
| Tanichthys albonubes |  |
broad horizontal stripes; abundant red erythrophores |
