Hi Dr. Ford,
My 4th grade students are currently doing research on whales and small
science experiments that help them better understand how they live.
We are curious...are whales larger in certain regions of the world? Do they
lose or gain weight in the summer or fall months?
Any help you can provide would be greatly appreciated.

Whale sizes on record seem to show some species of whales are larger in the southern hemisphere. There is a size difference due to sexual dimorphism in many species. For example the male killer whale is significantly larger than the female. the same thing is true in sperm whales.
In baleen whales the reverse is true females are much larger than males.
Baleen whales lose weight in the late fall and throughout the winter. Soon after the vernal migrations of these animals they begin to gain weight again.
All the best,
