AJHQ+A – Whales

Snowflake Daringwolf asks Tierney ‘how much can whales weigh?’ in this week’s AJHQ+A.

Have you ever wondered how whales sleep? Since whales breathe air like we do, they need to come to the surface even when they’re sleeping. Whales ‘sleep’ with only half of their brain at a time. One half stays awake to keep the whale breathing and aware of any danger, while the other half rests.

Some whales can live to be 200 years old or more! There may be whales alive that are even older. Unfortunately it’s very difficult to tell how old a whale is while it is still alive. And usually when they die they sink to the ocean floor where it is very difficult for us to study. But there may be whales in the ocean that were alive before electricity was invented. Whoa!
