True
Dolphins have no sense of smell.
Infact verdict: True (86/100).
The claim that dolphins have no sense of smell is mostly accurate. Dolphins lack a developed sense of smell due to the absence of olfactory lobes and nerves, as supported by multiple sources. However, some studies suggest they may have a rudimentary sense of smell. Therefore, the claim is largely true but slightly misleading as it oversimplifies the complexity of dolphin sensory systems.
