Deep in the Forests....

     Heyy fellow bloggers! Today, we're gonna talk about animals. Last quarter, we talked about different kinds of animals as our CEO (Creative Expansive Output) for science. We're gonna say a few kinds of animals that we talked about...

    One kind of animals we talked about is the class Aves or the birds. These are animals composed of feathers, beaks, wings, and scaly feet. I was the one who reported this topic. Their wings are specially made for flight. There are many families of the class Aves, actually more than 20. Though, the oldest kind of bird is the Archaeopteryx. I prepared for this CEO through researching the net and making powerpoints and handouts. Here is an example of a bird, the pigeon:

     Another kind of animal we talked about are the mollusks or from the phylum, Mollusca. They have a hard shell that covers their body but their main body is soft. They are bilaterally symmetrical. They eat through using what they call radula that scrapes off nutrients from rocks and others. They move by using a muscular foot while marine mollusks move through jet propulsion. I prepared for this project by researching and I studied about the subject from many sources. It was hard to research because it is hard to find information about mollusks. Here is an example of a mollusk, the common garden snail:

     The next topic we are going to talk about are the vertebrates, fish. There are basically 3 classes of fishes. Class Agnatha, Chondricthyes, and Osteichthyes. The Agnathans are jawless fish and they are paraphyletic as such as the lamprey. The class Osteichthyes on the other hand, are made up of fishes with a bony skeleton and they are the class with the largest class of vertebrates today and they are primatively cold-blooded such as the rayfish. Finally, the class Chondricthyes are jawed fishes with cartilages with tooth-like scales called denticles, such as the shark. I prepared for this project by researching through books and the internet. It was hard to prepare because every topic I researched on, it only gave a few information. Here are example of a fish, the lamprey:

     Finally, here's the last topic we will talk about, the flatworms. They come from the phylum, Platyhelminthes. They are made up of 3 layers. They are, of course, dersoventrally flattened. They are bilaterally symmetrical. They reproduce both ways: asexual and sexual. Most flatworms are parasitic. I prepared for this topic by researching from different sources. This was quite hard for me to research because flatworms are hard to find in the net. Here is an example, the Pseudoceros dimidiatus:
