there are numerous small white and grey spots on tilu body. 1'he flippers

the very. wide indentation in the tail. -The rear ed,^e of the t ail is

1'he upper jaw is more curved than in roi.-qual.s, but much less
so than in right whales. Fl,ach 7:o1•1 of b^tl(Jen corlt-aills 140--180 stout
tiiiclc plates. The lar;,esv plates ^rrhich are ùp to 25-3b cril long) lie
either in the middle of the jaw or at the very beginning of the second
half of the row. In front, as in right ti•rhales, tile rows of baleen
are not joined together; they begin about 20-30 cm frora the tip of
the snout. The plates are white or yellowish.
Th e. oral cavity is narrow. The lower jaw is level with the
upper (in rorquals it sticks out considerably in fri)nt).. It bears
100 or more hairs; there are up to 50 or 60 on the upper jaw. A very
characteristic feature of grey Whales is a kee:l-lilce process on the
lower jaw, with wrlic'rl, it is thought, they plough up the sea-bottom.
The spout consists of two. jets, whicil dive.2.'Le at an angle

not greater than 30° .
There are 56 vertebrae r The cervical vertebrae are separate
(in right whales they fuse into asinE;le block), which permits considèz.'a.b.le
mobility of the hea,â. (other whales cannot move their heads).
There are 14 thoracic, 12--14 lumbar, and 21--23 caudal vertebrae.
Ther.e are four digits in the bony structure of the flippér.
