What Is A Vertebrate? What Characteristics Do
May 20, 2013What is a Vertebrate?What characteristics do chordates share?What characteristic do all vertebrates have?How do vertebrates differ in the way they controlbody temperature?
May 20, 2013Characteristics of Chordates vertebrates are a subgroup in the phylum Chordata members of this phylum are called chordates (examples: fishes,frogs, snakes, birds, mammals) most chordates are vertebrates, but a few are invertebratesAT SOME POINT IN THEIR LIVES, CHORDATES WILL HAVE ANOTOCHORD
May 20, 2013A notochord is a nerve chord that runs downthe back of a chordate, and slits in its throatareaSome chordates have notochords for their entirelife, however in vertebrates, part or all of thenotochord is replaced by a backbone
May 20, 2013Ner ve cord in back / slits in throat area
May 20, 2013Ner ve cord in backThe ner ve cord is the connection bet ween thebrain and the ner ves, where messages travel backand forth.Animals such as arthropods and segmented worms have a nerve cord BUTit does not run down their backs
May 20, 2013Slits in throat areaAt some point in life chordates have slits called pharyngeal (fuhRIN jeeul) or gill slitsSome chordates keep these slits as part of their gills (fishes),but for many the slits disappear before birth
May 20, 2013Characteristics of VertebratesA vertebrate has a backbone that is part of aninternal skeleton (endoskeleton) that supports thebody and allows it to move
May 20, 2013Backbone Also called a spine, runs down the center of avertebrates back Formed by many similar bones calledvertebrae Vertebrae are lined up in a row and havejoints/moveable connections to give the spineflexibility Each vertebrae has a hole the allows thespinal chord to pass through it
May 20, 2013Internal Skeleton (Endoskeleton) Protects internal organs helps give body shape gives muscles a place to attach skull protects brain ribs attach to vertebrate and protect the heart,lungs and other internal organsMany vertebrateshave arm and legbones adapted formovement
May 20, 2013Endoskeleton of a vertebrate Endoskeleton does not need to be replacedas the animal grows (unlike arthropod) Forms an internal frame that supports thebody against downward pull of gravity Vertebrates can grow bigger than animalswith exoskeletons or no skeletons at all
May 20, 2013Keeping Conditions StableDifferent types of vertebrates have different ways ofcontrolling body temperatureMost fishes, amphibiansand reptiles have a bodytemperature that is closeto the environment theylive inBirds and mammals havea stable bodytemperature that is oftenwarmer than theirenvironment
May 20, 2013EctothermsFishes, amphibians, reptilesAn ectotherm is an animal that does not producemuch internal heat Body temperature changes based on the temperature of theenvironment Sometimes called "coldblooded" however, their blood is oftenwarmExample: A turtle's body temperature will change as it entersa different environment - laying on a sunny riverbank vs.turtle swimming in cool water
May 20, 2013EndothermsBirds and mammalsAn endotherm is an animal whose body regulates its owntemperature by controlling the internal heat it produces body temperature usually does not change much even when thetemperature in the environment does - adaptations allowendotherms to live in a greater variety of environments sweat glands, fur and feathers are adaptations for maintainingbody temperatureOn HOT days endotherms SWEAT - cools the animalOn COOL days fur and feathers keep endotherms warm

Characteristics of Chordates vertebrates are a subgroup in the phylum Chordata members of this phylum are called chordates (examples: fishes, frogs, snakes, birds, mammals) most chordates are vertebrates, but a few are invertebrates
Page 1 of 8 Vertebrate Diversity, Function, and Evolution Objective: To recognise that all vertebrates share basic characteristics reflecting a common ancestry. 1-1 The Vertebrate Story 1) Evolution through natural selection is central to vertebrate biology. 2) More than 57,000 extant (living) species of vertebrates ranging from 0.1 g to 100,000 kg in .
It stresses major concepts of vertebrate anatomy and physiology in order familiarize students with the form, structure, and function of the vertebrate body, especially domestic animals. Scientific method of thinking and the experimental approach will be stressed. The topics studied in this course include a survey of all vertebrate species, and

vertebrate animals and invertebrate animals. A vertebrate animal has a backbone (spine or spinal column). Humans, dogs, sharks, owls, snakes, and salamanders are all vertebrate animals. Invertebrate animals don’t have a backbone. Worms, slugs, spiders, insects, squid, a
