A little about Cetaceans

Hi, my name is Grace and this is my blog. It’s a place where I will tell you about whales, dolphins, and other types of cetacea. I will post my drawings, poems and pictures of whales and some things will be for sale. Anything that is sold from this blog will have 50% of the money donated to a charity such as Save the Whales or Clearwater Marine Aquarium. When I find news about whales or petitions, I will post them on here so that you can help the whales too.

First, I would like to tell you about the types of cetaceans (that’s just a fancy Latin word for large sea animal.) The study of cetaceans is called Cetology. There are two types of cetaceans  – baleen and toothed whales. Mysticeti (from the Greek meaning moustache whale) are whales that have baleen. Baleen are not moustaches, they are plates that sits in the whale’s mouth that they use for filter feeding. The baleen is made of keratin and has bristles or hair (something like that) on the end of each baleen plate. Here is a picture from Wikipedia:

Some baleen whales are the blue whale, the humpback whale and the right whale. Baleen whales have two blowholes (toothed whales have one!) They filter feed on things like plankton, krill, small fish and sometimes crustaceans. Some baleen whales use bubble nets to catch fish. This youtube video shows humpbacks doing just that (if I were there I would be excited to see this too!)

The other order in the cetacean family is toothed whales or Odontoceti (think of an orthodontist or a dentist, they work with teeth.) Most toothed whales are smaller than baleen whales (well, except for the Sperm whale, it’s pretty big.) Toothed whales like the Orca the Bottlenose dolphin are easily trained to do tricks.

Though they should not be kept in captivity because they need a lot of room to swim and they prefer to live in pods as a family. Toothed whales have one blowhole and they use their teeth to eat fish, other whales, squid, otters, penguins, and other creatures that swim in the sea. These whales use echolocation to find their food.

Both types of whales can breach out of the water. They both migrate at different times of the year. They both use their hearing to find food and to follow their family. Sometimes humans do underwater testing and this hurts the whales’ ears. They might not be able to migrate or find food. Family is very important to both kinds of whales, they live in pods and like to be around each other.

I hope you liked this post.
