The Singing Swimmers of the Ocean!
Hi! I'm Caroline, and I'm going to tell you all about whales.
First, whales are seperated into two groups: odontoceti and mysteciti. Mysteciti are big whales that have bristles for teeth. Odontoceti are whales with cone - shaped, hard teeth, like bottlenose dolphins.
Whales used to be mammals that lived on land. They were called mesonychids, and they were wolf-like predaters with hooves and short legs. They caught fish the way bears do: along the shore: which is probably what led to evolving into whales. Scienticts think that seals are probably what mesonychids looked like when they were in the middle of evolution.
In Antartica, there are alot of whales that are mostly odontoceti whales. The few mysteciti whales there usually perfer being in the north pole, where they can get to eat their faverite food: krill!
Speaking of tundras, there are three types of tundras: alpine tundras, antartic tundras, and artic tundras. The antartic tundra's ocean is aplace that whales will call home for a long time! On this next box, you will find out alot about some of my favorite types of whales. :)
