All Fishes Data Sheet
Scientific Name	**Doras carinatus** (Linnaeus, 1766)
Common Name	Sierra Catfish
Type Locality	Lawa River (Maroni drainage) about 8 kilometers south-southwest of Anapaike/Kawemhakan, 3°19'31"N, 54°03'48"W, Sipakawini, Suriname.
Synonym(s)	Silurus carinatus
Pronunciation	DOOR ass
Etymology	Uncertainty surrounds the origin of this genus name which means either "armour" or "dagger". The fishes in this group have both sharp fins (which can be called dagger-like) and armour. Species named for spines on midlateral scutes based on Linnaeus (1766:504) reference to Linea lateralis subserrata & carinata spinis, ut in Scombris. Evidently, the scutes in D. carinatus reminded Linnaeus of the longitudinal keels in Scombris, presumably Scomber scombrus Linnaeus 1758, the Atlantic mackerel.
Species Information
Size	300mm or 11.8" SL. Find near, nearer or same sized spp.
Identification	Doras are distinguished among Doradidae by a unique combination of three characteristics exhibited by the postcleithral process. Body elongated, without scales but with a range of 33-35 spiny bony plaque which runs along the length of the lateral, starting from the extreme end of the caudal fin up to the point directly below the origin of the dorsal fin. Head is pointed and laterally compressed, its width being far less than its length. Eyes are high and are situated in the posterior half of the head. Mouth is inferior, provided with a pair of maxillary barbels branching into 12 or 13 branches and 4 short mandibular barbels. Adipose fin short
General Remarks	The Orinoco population (and thus that which is most currently likely to be encountered by aquarists) is the only one with specimens recorded over 30 cm SL. Can emit sounds by moving its pectoral spines. Every basic unit of sound emitted lasts for 60-70 millisecond, with a frequency of 60-90 Hertz corresponding to the reply frequency of the muscles utilized.
