ANIMAL DIVERSITY Systematics • study of biological diversity and its origins Its arms TAXONOMY focus on properly describing‚ identifying‚ classifying‚ and naming of organisms. CLASSIFICATION focus on placing organisms within groups that show their relationships to other organisms.

Aquatic Science P.5 3/23/2013 Invertebrate Research – Stove Pipe Sponge If a diver or went snorkeling‚ it would be very lucky to find the Aplysina archeri‚ also known as the Stove Pipe Sponge. This sponge is in the Kingdom of Animalia‚ Phylum of Porifera‚ Class of Demosphongiae‚ Order of Verongida‚ Family of Aplysinidae‚ Genus of Aplysina‚ and Species of A. archeri. This sponge gets its name from its cylindrical shape and long tube like structure. It can grow up to 150 cm long with diameter of

ION OF CLASSIFICATION OF NON-CHORDATES UPTO CLASSES WITH SALIENT FEATURES Vanramliana Pachhunga University College Aizawl‚ Mizoram 1. Phylum Porifera: From the Latin porus for pore and Ferre to bear‚ hence an animal with with pores. ~5000 species. Characteristic features:- a) Multicellular; no true tissue; asymmetric; sessile b) spongin- protein fibers for structure; spicules for skeleton c) filter feeders using collar cells (choanocytes) & amoebocytes

Vertebrates are animals that are members of the subphylum Vertebrata /-ɑː/ (chordates with backbones). Vertebrates include the overwhelming majority of the phylum Chordata‚ with currently about 64‚000 species Vertebrates include the jawless fish‚ bony fish‚ sharks and rays‚ amphibians‚ reptiles‚ mammals AND ‚BIRDS 20 Main Characteristics of Vertebrates Main Characteristics of Vertebrates are given below: 1) Well developed brain. 2) Brain lodged in to box or cranium. 3) Notochord‚ forms

Prevent other sponges from growing in their area 2. Protection from predators and paracites Sponge reproduction Reproduce both sexually and asexually

the end of this Reading Guide chapter‚ you will find a chart that may help you to organize this knowledge. Concept 33.1 Sponges are basal animals that lack true tissues 1. You may have learned in an earlier course that sponges are in the phylum Porifera. This group is now known to be polyphyletic‚ and all sponges belong to either phylum Calcarea or phylum Silicea. They are the simplest animals and lack true tissues. Label the following: pores‚ spongocoel‚ epidermis‚ amoebocytes‚ choanocyte‚ flagellum

"Write a three sentence description for each phylum and list two examples for each. Also‚ draw a picture of a common example from each. (or cut out of a magazine). You will be graded on how accurate your information is as well as neatness." Sponges (Porifera): Poriferans don’t have mouths; instead‚ they have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter nutrients from the water as the water is carried through the body. The flow of water through the sponge

1. The term “metazoan” is a synonym with “multicellular animal.” Are there any single celled animals? How are single-celled eukaryotes classified? 2. Give eight characteristics of sponges. Multicellular animals‚ body had pores‚ canals‚ and chambers‚ all sponges are mostly marine or totally aquatic‚ they exhibit radial symmetry or no symmetry‚ all adults are sessile and attached to the substratum no organs or true tissue are present‚ asexual reproduction occurs by buds or germmules‚ outer surface

Diversity in Living Organisms (Science) |Close X | |[pic] Classification And Evolution Classification refers to the identification‚ naming‚ and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore‚ classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of

Multicellular tissue organism‚ second branch from the ancestral stock‚ differentiated further to become two layered and three layered organisms. Those multicellular organisms which had
