Once described as a new species of Protocetus, the holotype remains were elevated to genus level in 1975. Although a different genus, Andrewsiphius would have still been a primitive toothed whale form similar to the more famous Protocetus. The rear limbs would still have been visible on the outside of the body, while propulsion was provided by the up and down undulation of the tail.
