This is very different from the way that toothed whales eat.

It is not yet known whether toothed whales regularly use such a weapon.

Certainly over toothed whales, the dolphins, can produce loud sounds.

Prosqualodon was related to and looked like modern toothed whales.

Toothed whales eat larger fish or meat and are like big dolphins.

In general, three different types of sounds are produced by dolphins (and other toothed whales).

Compared to toothed whales at that time, the squalodontids were likely more mobile.

Toothed whales' brains have a poor connection between the two hemispheres.

Narwhals, like other toothed whales, have big brains in relation to their body size.

It is a member of the family Delphinidae of toothed whales.

Echolocation, too, plays an important role in food hunting for dolphins and toothed whales.

Over half the species of toothed whales are dolphins or the closely related porpoises.

Toothed whales eat fish and squid, which they hunt by the use of echolocation.

Delphinoidea is the largest group of toothed whales with 66 genera in 6 families.

This deep-diving family of toothed whales are the least well-known cetaceans.

Polygamy, or at least random mating, seems to be the general rule among the toothed whales.

Indeed, mass stranding of toothed whales (Odontoceta) are relatively common around the world.

The insectivorous bats are not unique, for another group of animals uses a very similar system - the toothed whales.

Toothed whales is a suborder of the cetaceans characterized by having teeth.

Like all toothed whales, they are capable of echolocation for finding prey and group coordination.

They therefore rank as mid-sized species among toothed whales.

Melon size is unrelated to maximum dive depth in toothed whales.

A key factor in many of these cases appears to be the strong social cohesion of toothed whales.

They are part of the toothed whales.

From this, Odontoceti can discern the size, shape, surface characteristics, distance and movement of an object.

The Odontoceti includes all the whales which eat prey larger than plankton.

This makes them different from the Odontoceti.

The Odontoceti are a suborder of the cetaceans.

This distinguishes them from the other suborder of cetaceans, the toothed whales or Odontoceti.

Odontoceti also include dolphins and porpoises.

Members of the suborder Odontoceti, the suborder containing all the toothed whales and dolphins.

Suborder Odontoceti (toothed whales)

The ability to hear is particularly relevant for avoiding mammalian predators of the suborder Odontoceti (particularly dolphins), who use echolocation to find prey.

All are members of the cetacean order, which includes whales, and all belong to the suborder odontoceti, literally meaning toothed whales.

The genus Squalodon belongs to the order Odontoceti, the toothed whales (Kowinsky, J.).

The term whale sometimes refers to all cetaceans, but more often it excludes dolphins and porpoises, which belong to the suborder Odontoceti (toothed whales).

Both basilosaurids and dorudontids are relatively closely related to modern cetaceans, which belong to suborders Odontoceti and Mysticeti.

Odobenus rosmarus, the walrus Of the Cetacean Odontoceti, the Monodontidae:

Fossils indicate that before evolving baleen, Mysticeti also had teeth, so defining the Odontoceti via teeth alone is problematic.

Cetaceans - from the Greek ketos for sea monster - fall into two discrete categories, Mysticeti and Odontoceti, so-called depending on whether they have teeth.

As for dorudontids, there are some species within the family that do not have elongated vertebral bodies, which might be the immediate ancestors of Odontoceti and Mysticeti.

This likely means that, while the asymmetry in the Odontoceti skull has increased over time, the Mysticeti skull has evolved from asymmetrical to symmetrical.

Back beyond the Oligocene there is evidence only of archaeocetes, the rather large ancestral toothed whales that apparently gave rise to both the Odontoceti and Mysticeti.

The order contains two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales, which includes dolphins and porpoises).

The locality of Cerro das Mós, from where a large crocodilian (Tomistoma schlegelii) tooth was collected long ago, has also produced some Odontoceti teeth.

However more recent studies, based on various combinations of comparative anatomy and molecular phylogenetics, criticised Milinkovitch's analysis on technical grounds and reaffirmed that the Odontoceti are monophyletic.

A year or more is the time taken by toothed whales.

There are 30 species of toothed whales in the world today.

This is very different from the way that toothed whales eat.

What ever it's name it remains the largest toothed whale in the world.

Unlike in toothed whales, sound does not pass through the lower jaw.

It is the largest among the toothed whales, weighing about 170 g.

It is not yet known whether toothed whales regularly use such a weapon.

Scientists there are studying how dolphins and toothed whales hear.

Certainly over toothed whales, the dolphins, can produce loud sounds.

Toothed whales can also be threatened by humans more indirectly.

Prosqualodon was related to and looked like modern toothed whales.

Toothed whales eat larger fish or meat and are like big dolphins.

Such values are very close to those established previously for small to medium size toothed whales.

But the toothed whales had a more interesting response to the problem when they developed echolocation.

Our studies have shown that the sounds of bats and toothed whales are surprisingly similar.

In general, three different types of sounds are produced by dolphins (and other toothed whales).

Being a toothed whale, pilot whales have a single blow hole.

Fossils discovered later, nevertheless, showed that this was a toothed whale.

It is analogous to the melon found in other toothed whales.

Two proteins have been found to play a major role in toothed whale echolocation.

Toothed whales - a group which includes smaller whale species and dolphins.

Toothed whale whistles do not appear to be used in echolocation.

Both are toothed whales which eat fish and squid.

It is significant that only the toothed whales which use echo-location have been trapped here.
