Q&A+website

This part is from the Q&A website.

This is what I learned!

~The question is," Can ocean mammals such as whales and dolphins live in fresh water lakes and rivers temporarily? Which ones can't?" This question interested me. Dr.Greg Stone said that the animals could live in the fresh water, but only temporarily. The would soon become tired from the lack of buoyancy in the water. Another issue with that is food. I don't think you will find krill in a lake, so a whale might starve to death. Also, if a marine mammal's skin and eyes become exposed to fresh water for too long, it could cause damage, irritation and other issues. I am interested in this topic and I want to learn more about this. Hopefully I can research more on this later...

~ Another thing I learned is that the BIG drop in krill is affecting a lot of animals that eat krill like whales. Since whales eat krill and there isn't any around, not only can we say good-bye to krill, but whales as well. Also, I learned that krill depend on sea ice to survive. If climate change and global warming is melting our sea ice then it is affecting the sea krill. It's sort of like a chain reaction. One thing leads to another. :-`(

~ One other topic I learned about was about memory with marine mammals. Seals and dolphins display their memory by remembering how to forage for food, how to avoid certain predators, and how to remember other animals by vocalization. This was so cool and interesting!
