Nematodes The phylum Nematodes also known as roundworms are one of the most common phyla of animals. There are over 20‚000 different species of roundworms. Roundworms can be found in water‚ and on land. Roundworms have a complete digestive system with two separate openings one for food and one for getting rid of waste. This type of digestive system is very common in complex animal. Nematodes use external and internal pressure and body movement to move food through their digestive tracts

Pharyngeal Gill Arches In high school I wrote a twenty minute speech for my public speaking class. The goal of the assignment was to pick a topic that we were curious about and didn’t know much about‚ and write an informative speech about it. I chose to write about the evidence for evolution. I learned about fossil evidence‚ genetic evidence‚ embryonic similarities‚ and homologous traits between seemingly unrelated species. In college‚ I took biology classes and learned that my speech that I wrote

Man-of-War The Portuguese man-of-war if a member of the Kingdom Animalia‚ phylum Cnidaria(1)‚ class Hydrozoa‚ order Siphonophra‚ the genus Physalia‚ and the species Physalia(2). The man-of-war is not an actual jellyfish‚ but a Siphonophor. Also the man-of-war is not a single organism. It is made up of many different organisms that work together. These organisms are called polyps. The Portuguese man-of-war is usually found in the Northern Atlantic gulf stream. It can also be found in the tropical
