Cetacea


Ce-ta′ce-a

,
Noun.
pl.
[NL., from L.
cetus
whale, Gr. [GREEK].]
(Zool.)
An order of marine mammals, including the whales. Like ordinary mammals they breathe by means of lungs, and bring 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.
