Developmental plasticity and the origin of tetrapods.
Ottawa, Canada. In Nature, 2014
Polypterus is a member of the basal-most group of ray-finned fish (actinopterygians) and has many plesiomorphic morphologies that are comparable to elpistostegid fishes, which are stem tetrapods.
Natural flexible dermal armor.
San Diego, United States. In Adv Mater, 2013
Here we seek to find the means by which Nature derives its protection by examining the scales from several fish (Atractosteus spatula, Arapaima gigas, Polypterus senegalus, Morone saxatilis, Cyprinius carpio), and osteoderms from armadillos, alligators, and leatherback turtles.
Innervation of lung and heart in the ray-finned fish, bichirs.
Messina, Italy. In Acta Histochem, 2008
The present review paper describes the presence of nerve fibers located in the muscle layers of the lung and its submucosa, the collection of unipolar neurons found in the submucosal and muscle layers of the glottis in a bichir species (Polypterus bichir bichir).
Materials design principles of ancient fish armour.
Cambridge, United States. In Nat Mater, 2008
Here, we present a multiscale experimental and computational approach that reveals the materials design principles present within individual ganoid scales from the 'living fossil' Polypterus senegalus.
