Lift produced by the Heterocercal Tail of Acipenser

Nature, 1966
THE upward forces produced by the heterocercal tails of two species of Selachii, moving transversely through water at various speeds, have recently been measured1. It was found that the lift was approximately proportional to the 1.4th power of the transverse speed.

The development of the scales of Acipenser ruthenus

Journal of Morphology, 1926
AbstractThe different kinds of scales characteristic of the adult sturgeon are described and the facts of ontogenesis which throw light on the history of these structures are presented.The scales of Acipenser are exclusively mesenchymatous and therefore are not morphologically comparable with the placoid scales of elasmobranchs.
