How Do Whales Sleep?

All mammals breathe in oxygen and exhale carbon dioxide with their lungs.  Land mammals do not have to think about breathing,  it happens naturally thanks to the part of our brain called the brain stem.  This area handles breathing and the other  involuntary things our amazing body does  for us.

Whales and dolphins, on the other hand,  need to “think” about breathing.   It’s not the intense type of thinking required for a math test, but a thinking that can occur only when the brain is awake/conscious.  Therefore, whales can’t go into a deep sleep like we can.  So, how do they get their sleep!!?   To discover the answer, click  here.
