Journal of Fish Biology, 2021 AbstractLarval attachment organs (LAOs) are unicellular or multicellular organs that allow larvae to adhere to a substrate before yolk‐sac absorption and the free‐swimming stage. This study documents the LAO of tropical gar, Atractosteus tropicus, using a combination of scanning electron microscopy and light microscopy.

Diversity of Mesozoic semionotiform fishes and the origin of gars (Lepisosteidae)
Naturwissenschaften, 2010 Gars (Lepisosteidae) are ray-finned fishes with controversial relationships to other actinopterygian lineages. When fossil taxa are considered, gars are grouped with Mesozoic macrosemiids and 'semionotids' in the Semionotiformes, but the intra-relationships within this order are still elusive.
