 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Corydoras zygatus Eigenmann & Allen, 1942 |
| Common Name(s) | None |
| Type Locality | Río Hallagua system, Yurimaguas (5°54'S, 76°04'W), Loreto, Peru. |
| Pronunciation | Kory DOOR ass - z eye GAT uss |
| Etymology | Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. Zygatus from the Greek zygados: team, pair. On the similarity with Corydoras rabauti |
| Species Information | |
| Size | 70mm (2.8") SL. Find near, nearer or same sized spp. |
| Identification | Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras. C. zygatus background colour is pinky-grey, fins are colourless or slightly sooty. Adults have a copper "eyebrow". There is a dark line which always has a green shine to it, this line ends on the caudal peduncle never extending onto the caudal fin and without the downward twist that C.rabautihas and with which it is often confused. There often is a vertical line through the dark stripe just at the base of the dorsal spine, this manifests itself as a break in the stripe. C.zygatus show a number of vertical grey bars on the forward most ventral scutes, rabauti can have this as well but it "usually" shows as a dark smudge without the distinct bars.Adult zygatuscan become scruffy looking. Differences are clearly visible when looking at the fry of the two species. |
