forth living young which they suckle for some time. The
anterior limbs are changed to paddles; the tail flukes are
horizontal. There are two living suborders:
(a) The {Mysticete or whalebone whales, having no true
teeth after birth, but with a series of plates of
whalebone [see Baleen.] hanging down from the upper jaw
on each side, thus making a strainer, through which they
receive the small animals upon which they feed.}
(b) The {Denticete, including the dolphins and sperm whale,
which have teeth. Another suborder (Zeuglodontia) is
extinct. The Sirenia were formerly included in the
Cetacea, but are now made a separate order.}
