In the viviparous Teleost Poecilia reticulata the Rohon-Beard cells are not detected in the developing spinal cord. This agrees with observations made on another Teleost (Gambusia affinis) belonging to the same family and correlates the viviparous condition with the absence of the Rohon-Beard cells. The "supramedullary neurons" detected in adult Gambusia are not observed in Poecilia. This indicates a different pattern of these neurons also in species belonging to the same family.
