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!
Giraffes are back in Jamaa!! They’ve traveled far and wide and have lots of tales to tell.
There’s only one species of giraffe, and they are only native to Africa. They have different spots depending on which part of the country they live. They are the reticulated, Nubian, Uganda or Baringo, Masai, Angolan, and the southern. All giraffes have two furry little horns called ossicones.
Giraffes drink little water and only eat acacia leaves. They get most of the water they need to survive from the leaves. They’ve adapted this way because when they are drinking they are extremely vulnerable as this is the only time predators can stage an attack. But they’re generally not worth the effort as they have very keen eyesight, can kill with a kick, and their skin is extremely tough to chew making them more work then their worth.
Frozen Fuzzystar asks Brady Barr ‘why do monarch butterflies migrate?’ in this week’s AJHQ+A.
Do you want to know some more interesting things about butterflies?
Butterflies taste with their feet! Different species tend to lay their eggs on only one type of plant, so it’s important to find the right one. They have tiny spines on the back of their legs called chemoreceptors (key-moe-ree-sep-ters) that can tell the right plant taste!
Butterflies drink from mud puddles. Just like us, they need vitamins and minerals to live healthy lives. Mud puddles are rich in minerals. When a mud puddle is found you can often find a group of butterflies sipping from the same pool. This is called puddling.
