"The voice of
the dolphin in air is like that of the human, in that they can
pronounce vowels, and combinations of vowels."
Stenella longirostris, commonly known as Spinner dolphins, are marine mammals with
elongated, slender bodies that are optimal for swimming and
jumping. These mammals are typically around two meters in length
and are on average about 90kg. The anterior side of this animal
is equipped with a long, thin beak, strong jaws and sharp teeth.
Behind the eyes are the External Auditory Meatus, or the ears.
The lean dorsal side is extremely narrow and lined with 68-81
The dorsal fin and pectoral fins (flippers), located near the
back and the belly, aid in direction and navigation through the
water. Each of these maneuvering devices contains bones similar
to that of a hand, which can be used as a wing to guide the
dolphin through the water. The posterior end contains a thick
tail stock and two flukes, that move in an up and down
pattern. The female Spinners usually have a genital and anal
opening on the ventral side, with a nipple located in the
mammary slit on either side of the genital opening. The males
generally have a genital opening located on the ventral side as
well, with a separate anal opening to the anterior side. Each
specific species of dolphins have their own color pattern;
Spinners are typically dark gray on the dorsal side and white on
the ventral side, with a lighter gray running from the the eyes
to the tail on the sides.
