It is winter here in Myrtle Beach and we spend the time getting our ocean going ready for spring. We are still going on deep sea fishing ventures, but you will have to wait until spring for the next Dolphin Watch Cruise.
You may be wondering, however, where do dolphins go in the winter?
Dolphins need to breathe just like humans, so every 30 minutes or so they need to surface and breathe. For this reason, dolphins do not hibernate under water. Also, they do not migrate as a group or family unit with a pattern that anyone can define. This does
Consider This About Dolphins
As we mentioned, they do not hibernate given they do not have an involuntary breathing respiratory systems like other animals as well as human beings. Breathing is an intentional act they need to think about. One interesting fact is that only half of a dolphin’s brain actually sleeps at any given time. How do we know? Electroencephalograms conducted by scientists. For approximately eight hours a day they sleep and off (kind of like humans at work.)
Sleep Patterns of Dolphins
Dolphins need to rise to the surface to breathe through what is called a blowhole about every 30 minutes when they are in deep water. This will happen more frequently if they are in more shallow water. Sometime a dolphin will rest close to the surface of the way with their blowhole exposed or they will swim very slowly in pairs in a semi-conscious state. When this is happening, they keep one eye open and that eye is not correspond with which half of the brain is sleeping. Usually dolphins will swim in sets when sleeping and keep one eye open and focused on the other dolphins.
There is no definitive migration pattern for dolphins and they do not move to another location in large groups like other mammals. There is some evidence that some do move in the winter season, however, not a great distance like geese or other types of birds. In areas, other than Myrtle Beach, where the weather is more extreme such as the North Atlantic coast, some dolphins will migrate south to warmer waters.
A study was done in the United Kingdom where dolphins migrated to southern Cornwall and then moving north as the weather became warmer. However, scientists could did not observe a specific pattern to their migration.
As spring starts getting closer we start thinking of warm summer days and there is no better way to spend family time than taking a long dolphin watch cruise with the Voyager crew. Don’t let another summer go by without treating your family to this great adventure.
