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

CHAPTER NO-5 KINGDOM ANIMALIA Phylum Porifera (GK: Porous = Pores + Ferro = form) Main characters: 1. They are commonly called as sponges. 2. They are sessile animals. 3. Sponges range in height from about 1cm to 2cm. 4. More than 5000 species of sponges are found. 5. All are marine‚ while some are fresh water. 6. The central body cavity is called spongocoel. 7. A single large opening is called as osculum. 8. They are filter feeders. 9. Body lining is formed by flagellated cells

sponges. The phyla’s that do have three germ layers are the: Flatworm‚ roundworm‚ mollusks‚ echinoidea‚ chordates and the arthropods. (Clc.U.C.edu. 1997) 4. One phylum on the table has more species that all the others. State the name of this phylum‚ and provide several different examples of the species found in the phylum. The phylum that has more species than the others is the Arthropoda. Examples found in the arthropoda are: cockroachs‚ ants‚ flies‚ bees‚ beetles‚ and butterflies. (Biology Questions

Classification of Animals Animals divided into 35-40 phylum 32.3.1 Tissue symmetry separate the Parazoa and Eumetazoa Kingdom Animalia (Metazoa) is divided into 2: Parazoa Animals that lack tissue and symmetry Ex. Porifera (Sponges) Eumetazoa (true animal) Animals that have definite shape and symmetry and have organs All bilateria animals are triploblasty Can be protostomes or deuterostomes (depends on blastopore development) Only Cnidaria (sponges) and Ctenophora are diploblasty 32.4 The

this essay I will talk about two kinds of organisms that are called worms. That’s organisms use it in a labs. Which are the flatworm and the roundworms. However‚ every kind belongs to different phylum‚ so they are not closely related to each other. Flatworms ( phylum Platyhelminthes) and roundworms ( phylum Nematoda)‚ but there are many similarities and differences between these two types of organisms. Similarity: • There are many similarities between the two groups of worms‚ Platyhelminthes and

2.) A Brief List of 21 Animal Phyla A. Invertebrate Phyla Parazoa: Simple animals without a digestive cavity. 1. Phylum Porifera (Sponges) Simple multicellular animals that spend their lives anchored to a rock or ocean bottom; they are mostly marine but some species live in fresh water; sponges have radial symmetry with a cylindrical‚ globose or irregular body containing an internal skeleton of minute spicules made of calcium carbonate‚ silica‚ or a fibrous collagen protein called spongin; the

smaller groups‚ called Phyla. Each Phylum is split into smaller groups called Classes‚ each Class is split into Orders‚ each Order is split into Families‚ each Family is split into Genera‚ and each Genus is split into Species. A Species is a single organism‚ not a group. Some examples of species would be Southern Leopard Frog‚ Honey Mushroom‚ or White Oak. All seven types of groups go in order from largest to smallest‚ like this: ➢ Kingdom ➢ Phylum ➢ Class ➢ Order ➢
