From: Development of the caudal-fin skeleton reveals multiple convergent fusions within Atherinomorpha
Evolution of the caudal-fin development within Atherinomorpha. A generalized scheme of hypothetical developmental stages (left column) and the adult state (right column) are shown for four studied higher atherinomorph taxa. In addition to the extant taxa, the reconstructed grundplan is drawn for each node respectively. Colour code: compound centrum, grey gradient; extra caudal ossicle, pink; epural, dark blue; haemal arch, grey-brown; haemal spine, light grey-brown; hypural 1 & 2/lower hypural plate, yellow; hypural 3 & 4/upper hypural plate, orange; hypural 5, red; inter-haemal spine cartilage 3, mint; neural arch, brown; notochord, white; neural spine, light brown; parhypural, light blue; preural centrum, light grey; ural centrum 1, dark grey; ural centrum 2, semi-light grey; ural centrum, grey; uroneural, violet
