Description

edit

Hyphessobrycon caru grows up to a length of 2.5 cm (0.98 in). It has a brown to black spot on his dorsal fin. Its few, irregular but vertical ordered pigment cells in its shoulder area are an important difference to related characiformes. The males, in contrast to the females, have small bone hooks at their anal and pelvis fin rays.[1]

Species distribution

edit

The fish has only been found in the upper drainage basin of the Pindaré River, a left tributary of the rio Mearim in the federal state Maranhão in the northeast of Brazil near the Atlantic coast.[1]
