Abstract
- The shape of haemal arches of the vertebral column in several species of South American atherinids was analyzed. A large amount of variation was found, from species showing greatly expanded haemal arches connected to one another forming a cone or funnel, to others with completely unexpanded arches. The first case is hypothesized as the specialized (apomorphic) condition within the Atherinidae, on the basis of ontogenetic development.
