Detailed explanation-1: -Dolphins and sharks both have dorsal fins on their backs, two pectoral fins on their sides, and a tail. Sharks’ tail fins are vertical and they use them in a side-to-side motion to swim, while dolphins’ tails are horizontal and they use them in an up-and-down motion to swim.
Detailed explanation-2: -Although their differences are certainly substantial (e.g., sharks are cold-blooded and dolphins are warm-blooded), sharks and dolphins have some undeniable similarities: side fins, a dorsal fin, and a torpedo-shaped body.
Detailed explanation-3: -Dolphins are mammals. They also have lungs, meaning they need to come to the surface to breathe using their blowhole. Sharks on the other hand, are cartilaginous fishes of the class Chondrichthyes, meaning their skeletons are made of cartilage rather than bone.
Detailed explanation-4: -Streamlined bodies and fins are traits that dolphins and sharks evolved separately, both as adaptations for swimming. This means that sharks’ and dolphins’ similarities (body shape, fin, and flippers) are convergent traits that each lineage evolved independently.
