Dolphins have the unique ability to turn off and on diabetes

Scientists found that the mammal can induce the condition when there is little food around and turn it off when food is abundant.

Scientists from the US National Marine Mammal Foundation said that bottlenose dolphins are resistant to insulin - just like people with diabetes only in dolphins, this resistance is switched on and off.

They believe it is a unique ability in the animal kingdom and results from the mammal’s need to maintain high blood sugar levels to feed its big brain.
