Introduction to the Subphylum Vertebrata,eries of small skeletal structures, the vertebrae. These are associated with the notochord during embryonic development but in most cases replace it in adults. Like the notochord the vertebral column functions as an axial supporting rod, but it has the additional function of protecting the nerve cor

Vertebrate diversity,us vertebrates have adapted their basic structure at different levels of organization to a variety of different modes of life. Vertebrate zoology is a vast subject with an extensive literature. Since vertebrates include most of the largest and most conspicuous animals, as well as man’s food, and dom

Phylum Annelida,system are found in forms such as the nemerteans; however such systems are far more complex in the coelomates, elaboration being due to a large extent to their possession of a coelom. Coelomates also show increasing complexity within their nervous system associated with more elaborate behaviour patterns.

,Epilogue: Uncaging Chaucer’s Animal Voice,ive to ‘Cnidaria’, is actually synonymous with the term Radiata. Whereas Porifera are multicellular forms which function at a cellular level of organization, the radiate phyla are more advanced. These phyla function at the cell tissue level, with similar cells aggregated into definite tissues.

https://doi.org/10.1007/978-88-470-0690-4in spite of their relatively recent emergence, chordates have established themselves as one of the major animal phyla, with dominance of the water, land, and air. They cannot rival arthropods in terms of numbers of either species or individuals, but outstrip them in terms of total biomass and ecological dominance.
