Scientific Name	**Corydoras oxyrhynchus** Nijssen & Isbrücker, 1967

Type Locality	Gojo Creek, tributary of Saramacca River, 6 kilometers south of Posoegroenoe, Brokopondo, Suriname.
Pronunciation	kor ee doh rass (lineage one).
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. This specific epithet refers to its sharp (oxys=sharp) snout (rhynchos=nose, snout).
Species Information
Size	50mm or 2" 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.
Sexing	Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
