Today’s whales are divided into two major groups: odontocetes, or toothed whales, and mysticetes, or baleen whales.

However, odontocetes are an exception to the rule amongst mammals.

In Japan, odontocetes that travelled in more industrialized areas carried higher contaminant loads than those found in more remote areas (Endo et al. 2003).

Jointed limbs are found in only two groups of animals: the arthropods and vertebrates.

They are divided into two groups: Odontoceti (Cetaceans provided with teeth) and Mysticeti (Cetaceans without teeth).

They belong to the order of odontoceti (that is, cetacea with teeth).

The book is divided into two parts: Dispelling Myths and Practice.

Their teeth are flat and blunt—much different than the spear-like teeth of most other shark species.

All the other families are Odontoceti, which means that they have teeth.

Small odontocetes rely on their speed and agility to escape predators.

Many species of small odontocetes are threatened by commercial fishing operations.
