Distribution
Doras species are distributed in South America. D. carinatus inhabits the Essequibo River basin and other coastal drainages east to the mouth of the Amazon River, and is possibly in lower Amazon and lower Orinoco River basins.[2] D. micropoeus is found in the Essequibo, Demerara and Courantyne River basins and possibly other coastal drainages east to mouth of Amazon River.[3]
Description
D. carinatus grows to a length of 30 centimetres (12 in) SL.[2] D. micropoeus reaches a maximum size of 35 cm (14 in) SL.[3]
D. carinatus can emit sounds by moving its pectoral spines. Every basic unit of sound emitted lasts for 60–70 milliseconds, with a frequency of 60–90 hertz corresponding to the reply frequency of the muscles utilized.[2]
