The aerodynamic shape and lightness of the blue shark body allow it
to move “elegantly” across the oceans. It exhibits countershading like
many other sharks. The upper part is an indigo blue tone while the
ventral and the sides are white.
It has a long caudal heterocercal fin. The second dorsal fin measures
almost half the size of the first and its pectoral fins are unusually
long compared to other sharks. Its eyes are large, its teeth are

female tends to measure little more than 1 meter in comparison with the
male.
