Scientific research of the SCO countries: synergy and integration
Report on the first capture of the Mississippi carapace Atractosteus spatula (Lacepde 1803) (Actinopterygii, Lepisosteiformes, Lepisostedae) in the Amur River near the city of Khabarovsk. The morphological characteristic of the Mississippian shell of the Amur River is given for 40 plastic and 21 meristic characters.

Copeia, 2015
This is the first in a planned series of studies in which we examine the cranial muscle ontogeny of exemplar taxa of actinopterygian clades to obtain a better understanding of the evolution of the cranial musculoskeletal system within the Actinopterygii. The Longnose Gar, Lepisosteus osseus, is a member of the basal actinopterygian family Lepisosteidae.

Neuroscience Letters, 2007
Immunohistochemical and electron microscopic studies were carried out to elucidate the structure of the serotonergic neuron system in the spinal cord of the spotted gar, Lepisosteus oculatus, a nonteleost actinopterygian. Serotonin-immunoreactive (5HT-IR) cell bodies and fibers were widely distributed in the spinal cord, constituting an intrinsic ...
