Dolphins are conscious breathers, which means they have to think about every time they want to take a breath. They respire through a nasal opening called the blowhole, which is located on the top of their head. When resting, their blowhole remains tightly shut. They are able to hold their breath for an average of 4-5 minutes and a maximum of about 10 minutes. Dolphins are efficient breathers. They are able to exchange 80% of the air in their lungs with each breath, while humans are only capable of exchanging 17%.

Because geese are so sensitive to forces, the iron "points" them in the right direction (just like in humans as we have enough iron in our bodies to make a 2 inch nail, but our iron levels are dispersed throughout us, and we are not nearly as sensitive, so this does not work on us, so don't try to magnatize yourself).
