Abstract: Morphological characters in adult fishes are often of complex nature which makes the identification of their onto genetic origin difficult to impossible. In most cases ontogeny is the only reliable source to identify shared (homologous)structures and therefore the basis to correctly uncover evolutionary relationships. This is where early life history stages come in to play. Complex morphological characters in larval fishes are often in a simple stage of development compared to their adult congeners, therefore the comparison of those characters are easier and more accurate. For most marine fishes however,early life history stages are unknown which makes it equally challenging but also exciting to work with these taxa. I will present examples of my own research to show how significant early life history stages are for phylogenetic studies of fishes.
