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. Writing a scientific name. • Kimberlicus beltranus • Kimberlicus beltranus The Protozoans Protozoa Alveolates Ciliates Sporozoans Dinozoans Amoeboids Amoebozoa Cercozoa
Premium Arthropod Cnidaria Phylum
Out of these‚ phylum Annelidia composed of about 15‚000 species which is further divided into 3 main classes – the Polychaeta (marine worms)‚ the Oligochaeta (earthworms and freshwater worms) and the Hirudinida (leeches). On the other hand‚ phylum Arthropoda is the largest animal phylum which is composed of millions of species with more than a million being described (Solomon et al.‚ 2011). This phylum is further divided into five major subgroups – subphylum Myriapoida‚ subphylum Hexapoda‚ subphylum

Arthropods are part of the largest and most diverse phylum in the animal kingdom. The phylum which I am speaking of is called Arthropoda‚ which is Latin for "jointed feet." Arthropods are arranged of more than one million invertebrate species within four subphyla. The four subphyla consist of five classes of Uniramia including insects‚ three classes of Chelicerata including horseshoe crabs and arachnids‚ Trilobita (which are extinct)‚ and Crustacea. When you break down an arthropod you will find

Classification The crayfish falls within the kingdom - anamalia‚ phylum - Arthropoda‚ Class - Crustacea‚ Order -Decapoda ‚ and family - Cambaridae. Habitat Crayfish like to be where it’s dark and cool‚ and during much of the daylight they will be found by them selves‚ under a rock or vegetation‚ waiting for dark‚ when they come out to forage for food. This is highly variable‚ ranging from deep holes to sluggish streams. A suitable habitat is medium-sized streams containing riffles and rocky pools

Due to the scope of our course‚ you are likely to see more general questions on individual phyla. For each of the phyla that we highlight in the questions that follow‚ try to know the characters that are

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

The story of the phylogentic tree of the animal phyla Animals never just started out as being classified among 9 different phyla. It started off with a single group known as the Ancestral colonial protists or Ancestral stock. From this stock‚ multicellular organisms developed. These multicellular organisms then later branched off into two separate directions. One branch turned into organisms which were asymmetrical‚ with no true tissue layers and no gut although it has two cell layers – the
