The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function. 
Flipper and tails are locomotory organs in the whale  and helps the whale in propelling similarly fins in the fish assist the fish in swimming. Both the strcutures have evolved differently and are made of different materials.

Answer:
Sensory transduction
Explanation:
Sensory transduction is a process by which the sensory neuron transforms the obtained sensory information into an electric signal. Sensory neurons are the afferent neurons and are activated when they receive stimulus from a sensory receptor. This is followed by the firing of action potential to convey the sensory information into the CNS through the cranial or spinal nerve.
Change in temperature serves as a stimulus for thermosensory neurons present in the skin. The activated thermosensory neuron then produces an electric signal by the process of sensory transduction during which a nerve impulse is generated and action potential to convey the information.
