I believe some tracking dogs and hounds have the keenest sense of smell.

the sharks sixth sense is to feel electromagnetic pulses in the water using its "lateral line".

Sharks longest sense is blood
yes all sharks have a sense of smell because a shark carnivores use them to find prey and other sharks use it to find whatever they eat (^^^)
sharks have a very good sense of smell, some say they can sense a drop of blood from miles away in the ocean
Dolphins hide from sharks and dolphins can also sense danger.
