       A relative of other primitive whales such as Dorudon and Zygorhiza,‭ ‬Ancalecetus would have been a toothed predatory whale that hunted other marine organisms for food.‭ ‬In fact,‭ ‬Ancalecetus is seen to be very similar to Dorudon atrox with the exception of the fore limbs of Ancalecetus being much smaller and closer to the body.‭ ‬This means that Ancalecetus would have had a reduced steering ability when compared to Dorudon,‭ ‬so it may have been a more specialised,‭ ‬perhaps slower predator.
