Dear Jessica,
Blue whales make sounds by passing air back and forth inside their bodies.
The moving air causes vibration in the tissues that they pass over. That is
heard as a hum. Those hums are very loud indeed.
Blue whales are very dark inside. Unlike refrigerators there is no light in
there. The insides if a blue whale are very much like the insides of any
mammal just much bigger. Lungs , heart stomach , intestines, liver, small
spleen, kidneys and brain all just like us only twisted around to fit their
life in the ocean.

Subject: questions about blue whales
Dear Dr. Ford,
I learned that blue whales have blubber. They eat 30 million krill
each day. I went on the Internet I heard a hum of a whale. How do blue
whales make the sounds they make?
Sincerely,
Jessica
P.S. What are blue whales like inside?
