More good questions from Mr. Niessen's Room!
1. Mothers don't have to teach their calves (babies) to swim. They
are born able to swim around and see things around them. Sometimes
the bigger problem for moms is that the babies want to swim around all
over the place and the mom sometimes has to chase them so that they
stay together!
2. Animals can communicate information in a bunch of different ways.
Whales can "talk" to each other with sound (for example, clicks,
whistles, and squawks), which is isn't produced by the mouth (like you
do), but thru the nose (the blowhole area). Studies are still looking
at whether dolphins can communicate information through taste
(chemical signals in the water). Dolphins can also communicate
information through body language. Dolphins spend a lot of time
touching each other, so depending on how you're being touched, would
give you a lot of information (for example, there's a difference for
people if someone hugs you or kicks you). Visual communication is
also important. Color patterns on the body would help dolphins
recognize each other as species, or even as individuals. Body shape,
movement, or posture also provide information (for example, when a
dolphin moves its jaws as if it's trying to talk, it's actually a mad
dolphin).
3. The only whales that eat sharks are killer whales (actually the
largest member of the dolphin family, which is part of the toothed
whale suborder). Killer whales are known to eat a variety of sharks
including blue, basking, reef shark, and even the whale shark (for
more information on the whale shark, look at one of the questions from
earlier this week on WhaleNet).
4. There are a number of whale and dolphin species that eat squid, so
there are probably those that also eat an octopus. Stomach contents
of some Gulf of Mexico bottlenose dolphins show an occasional octopus
having been a meal.
