Dolphins Can Stay Awake for Many Days
In a recent research, it has been revealed that dolphins are quite an active mammal, as they are able to remain awake for 15 days and may be more than 15 days. Researchers are not aware about more than 15 days, as they discontinued their study after it.
The research was being carried out on two dolphins at the National Marine Mammal Foundation. In order to reach at the above given result, the study researchers were of the view that they used sound test to know the level of their alertness.
A number of tasks were being performed from and on completion of every task, dolphins were provided with a gift of one fish. It was noticed that they carried out performing their tasks and without getting tired.
The study published in the journal PLoS ONE has found that the study researchers carried out test for 15 days. Study researcher Brian Branstetter was of the view, "The demands of ocean life on air breathing dolphins have led to incredible capabilities, one of which is the ability to continuously, perhaps indefinitely, maintain vigilant behavior through echolocationâ€ť. It now has been established that dolphins can remain vigilant and that too for so long.
