Beaked Whale Skeleton?

Is the Beaked Whale a whale with a beak or is it just a fancy name for a regular whale?
If in fact has a beak I would like to see an image of the skeleton.

They do have a beak and their skeleton is very peculiar.

A beaked whale is any of at least twenty species of small whale in the family Ziphiidae. They are one of the least-known families of large mammals: several species have only been described in the last two decades, and it is entirely possible that more remain as yet undiscovered.

Beaked whales are creatures of the ocean deeps, feeding, so far as is known, on or near the sea floor. They have an extraordinary ability to dive for long periods—20 to 30 minutes is common, and 85 minute dives have been recorded—and to great depths: 1,899 metres and possibly more. They are currently the only marine mammals whose evolution is believed to have been shaped by a secondary sexual characteristic (the male's teeth).

Beaked whales are moderately large in size, ranging from 4 to 13 metres in length, and weighing from 1 to 15 tonnes. Their key distinguishing feature is the presence of a 'beak', somewhat similar to that of many dolphins. Other distinctive features include a pair of converging grooves under the throat, and the absence of a notch in the tail fluke. Although Shepherd's Beaked Whale is an exception, most species have only one or two pairs of teeth, and even these do not erupt in the females. Beaked whale species are often sexually dimorphic, with one or the other sex being significantly larger, and the adult males often possessing a dramatically bulging forehead.

This is a picture of the beak whale skeleton:
