PPT-Vertebrates

By Haya Al Rabban What are Vertebrates Vertebrates are animals that have backbones like Fish Amphibians Reptiles Birds and Mammals Fish Fish have slimy bony scales for protection and They also have gills for breathing They get thousands of eggs and they dont worry about the eggs. Embryological Evidence for Evolution. Development Videos & Articles. Main idea behind our activity was to determine how the similarities between the embryos of vertebrates provides evidence of evolution . _____ American Toad _____ Armadillo _____ Bald Eagle _____ Blue Whale _____ Cardinal _____ Chimpanzee _____ Chipmunk _____ Duckbill Platypus _____ Great White Shark _____ Green Tree Frog _____ Hagfish Learning Objectives : To explain how animals are classified into groups.. Key Words: . How do we identify living from non living?. There are seven essential life processes..  . To remember these processes meet . The . Protochordates. as Ancestors. Some living chordate groups may resemble the primitive vertebrate ancestors (. protochordates. ). Hemichordates. Burrows in marine sediments (acorn worms). (+) pharyngeal gill slits; . Animals with backbones. Animals with backbones or vertebrates are classified into 5 subgroups. Fish is the largest of vertebrates.. FISH. Breathe through a set of gills. Covered with hard scales. Reproduce by laying soft, non-shelled eggs. Khlood. . Noori. . Saeed. Course book. 1. SUBJECT OUTLINE. 2014-2015. 2. 3. Vertebrates and invertebrates. Subject title. 2. (. Theory. ). Credit hours 2.

Which of the following traits is shared by all vertebrates, at least in some developmental stages, except the lampreys?. notochord. vertebrae. cartilaginous skeleton. cranium (head). mouth with jaws. . Diversity of reproductive strategies. Strategy. Description. e.g.. Advantage. Disadvantage. INTERNAL FERTILISATION . The sperm cell then fuses with the egg cell . inside. the body of the female. . Page: 500 - 519. Phylum Chordata. Classification. Kingdom: Animalia. Subkingdom: Vertebrates (has a backbone). Phylum: Chordata (has a spinal cord). Three subphylums are under Phylum Chordata:. Subphylum Cephalochordata. Part 1. Introduction. Introduction. The story of vertebrate history unfolds over more than half a billion years.. This period has seen some of the largest, most complex organisms to ever exist.. Vertebrate diversity can be attributed to opportunity and to their novel features.. - Reptiles and Mammals -. Amniote. Egg. Amnionic sac – protects embryo. Allantois – disposal sac for embryonic waste, works with chorion in gas exchange. Yolk sac – storage and transfer of nutrients to developing embryo. The . Protochordates. as Ancestors. Some living chordate groups may resemble the primitive vertebrate ancestors (. protochordates. ). Hemichordates. Burrows in marine sediments (acorn worms). (+) pharyngeal gill slits; . Introduction. To survive in a changing world vertebrates must detect changes in their external and internal environments and make appropriate behavioral and physiological responses.. The ability to detect and respond to change is a basic property of life. Derived. = appearing later in the fossil record as a new evolutionary innovation, descendant character state. Clade. = all organisms within a single evolutionary lineage; stemming from a common ancestor (can also be called a .
