That the bodies of both sharks and whales have evolved into a fusiform shape is an example of ___________________________________.

Fusiform Shape

A streamlined, spindle-shaped body design seen in many aquatic animals, reducing water resistance and enabling faster movement.

Sharks

A group of elasmobranch fish characterized by their cartilaginous skeletons, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head.

Whales

Large marine mammals belonging to the order Cetacea, known for their intelligence, social nature, and in many species, their impressive size.
