toothed whales have teeth and a single blowhole.
The number of teeth varies by species; it ranges
from 2 (in some beaked whales) to 250 (some dolphins).
They are smaller than baleen(non toothed) whales.
Many species live in pods. Toothed whales have well-developed
echolocation that they use to locate food (fish,
squid, marine mammals, etc.) and other whales. Toothed
whales have asymmetrical skulls.
or baleen whales - These "great whales"
are among the largest animals on earth. They have
baleen plates instead of teeth, which they use to
filter food. They are larger than the toothed whales
and have two blow holes.
