Dear Ms Margaret Slowinski and clearly smart students,
So many good questions.
You are going to make me work hard.
Well that is what I am here for.
The whale is blowing out warm air. The warm air condenses ( forms water
droplets) when it hits the colder ocean air. There are times when some water
caught on top of the blowhole gets sprayed upward as well. Whales do not
shoot water out of their lungs and blowhole.
Dear Camilla Mia, and Karla,
Killer whales are whales with a special job. They are predators. Predators
have the job of keeping the other groupss of whales , dolphins and other
animals healthy. They eat other animals for a very simple reason. They, the
killer whales, are hungry. All killer whales do not eat other mammals many
eat only fish.
Check the websites for "The Center for Whale Research" www.whaleresearch.com
and "Orcas in Patagonia" www.naturephotography.net/orca.hmtl. another
wonderful site is stubbs-island.com/english/orca/index.html
You will see the different ways that killer whales eat.
Dear Mary and Jacob,
Blue whales can hear very well because their ears get the sound through the
skin over their ears. The outer earhole is the size of a pencil but the
inner ear is the size of a small grape fruit and specially adapted to hear
very low sounds.
Dear Scott, Michelle, Matthew, Sam and Samantha.
Are you folks all in a club ?
A baby blue whale is about the same size and weight as an eight passenger
Dear Drew, Nicki and Kendall,
You guys are a more manageable group.
Blue whales have two blowholes because the blowhole is their nose. Like you
they have two nostrils in that nose. Toothed whales only have one nostril
Dear Zach and Mason ,
A female blue whale is larger than a male because she has babies. As I told
the club two answers ago a baby blue whale is huge. In order for the mother
blue whale to grow and feed such a baby she has to be enormous. Blue whale
mothers nurse their babies and need large amounts of stored nutrition to
make enough milk to feed the baby. Male blue whales only have to feed
themselves and so only eat for one. Mother blue whales are eating for two
and so have to store large amounts to feed the lucky baby whale.
Dear Tommy and Alex,
A blue whale can be as big as two large school busses parked end to end. A
measured blue whale was 40 meters long and weighed 94,000 kilograms. that is
,in our measurements, 131 feet long and 198,360 pounds or 99.18 tons. It
must have been a female blue whale.
Dear Anna and Kelly,
Blue whales get large by eating gigantic numbers of tiny things. A blue
whale like the one i told Tommy and Alex about probably ate two and a half
TONS of food a day. That is easy to do when you have a huge mouth. A 40
meter blue whale would have a mouth about 8 meters long and 5.5 meters wide.
All the children in your class could play dodge ball in that space. A large
suv weighs about two tons.
Whales sing in the ocean because the birds have used up all the trees. That
was a lame joke . I am sorry because whales sing for important reasons.
Different species of whales sing in different ways. Blue whales have very
deep voices and sing low songs slowly. Toothed whales, like beluga whales,
have high voices and sing quick high songs. All whales sing to communiate
and find mates. There are two record albums by Dr. Roger Payne and you can
hear different species sing. They are; Songs of the Humpback Whale and Deep
You have the most interesting question.
It is quite profound.
The short answer is .......yes.
All whales have come from an old group called archeocetes. Over several
millions of years they have diversified(changed) into the many types of
whales that we see today. There was even an old whale that had feet. It was
called pakicetus. Scientists are just now discovering several old fossil
whales that will have a lot to show us about how and when whales became
different from each other.
Blue whales are a modern species and were certainly not the first whales on
earth. They are however the biggest of them all. The older ancestors of the
blue whale were big but they were not true blue whales and much smaller.
This is another very good question. Whales are so big because they have to
be big. If people like us stay too long in water we get very cold. We get
cold because we are not big and do not have good insulation. Whales use fat
for insulation. The bigger an animal is the easier it is for that animal to
stay warm in water. So a big and fat insulated whale can stay warm easily
even in ice water.
Well this is a very bright and perceptive class. You have all asked good
questions . The best questions are always short and to the point. They are
also about ordinary things like singing and size and eating. There is also
nothing about any question that is wrong because it is a simple question. So
in the future please keep asking question about all sorts of things
GOOD JOBS KIDS
