Chordate

Chordates and Vertebrates Lab Introduction/Background: In this lab students are learning all about chordates and vertebrates and will be viewing examples of them as well. The examples to be viewed in the lab are Tunicates, Lancelets, Lampreys, Rays, a Dogfish shark, a Perch, Catfish, Eels, Toads, Frogs, Lizards, Snakes, Roadrunner (foot), Barn owl (wing), Cotton tail rabbit , and an Opossum. The different types of chordates/vertebrates discussed in this lab are the urochordata, cephalochordate,

Chordates have 4 common features; dorsal hollow nerve cord, notochord, pharyngeal gill slits and tail; define These characteristics of these animals are only present during embryonic development in only a few chordates. The notochord provides skeletal support, and develops into the vertebral column in vertebrates. The dorsal hollow nerve cord develops into the central nervous system, which is in the brain and spine. Pharyngeal slits are openings in the pharynx that develop into gill arches in bony

Introduction Chordates are an animal phylum that is classified by four main characteristics that they all obtain over the course of their lifespans. The first characteristic is the pharyngeal slits, which can be found in non-vertebrates, allow substances to enter and exit (Speer 2000). The dorsal nerve cord serves as a connection between the brain and other muscles (Speer 2000). The notochord can be found below the nerve cord and acts as a support system (Speer 2000). Finally, the post-anal tail

Animals share certain characteristics such as being heterotrophs, multicellular, no presence of cell walls, and many more. Animals can further be divided through the use of a phylogeny, which is an evolutionary tree. A phylogeny shows patterns of relationships between several different types of species. When branching off to dissimilar species, characteristics are taken accounted for whether they are derived, ancestral, or shared traits. Traits include symmetry, tissues, segmentation, body cavities

perch, chordate, and fetal pig they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of all animals before going into major detail about them. According to the online website named dictionary.com, Starfish are any echinoderm of the class Asteroidea, having the body radially arranged, usually in the form of a star, with five or more rays or arms radiating from a central disk; asteroid (dictionary.com). It is known that a chordate is

Phylum Hemichordata Phylum Hemichordata are marine vertebrates that live in shallow water. Hemichordates have two significant features with chordates which are pharyngeal gill slits and dorsal nerve cords. The name "hemichordate" means "half chordate," and hemichordates share some of the typical chordate characteristics. There are branchial openings, or "gill slits," that open into the pharynx; there is a rudimentary structure in the collar region, the stomochord, that is similar to a notochord;

Chordata family have four key features: notochord, dorsal hollow nerve cord, pharyngeal slits, and post-anal tail. Notochords are a flexible rod-shaped structure that is found in the embryonic stage of development along in the adult stage of some chordate species. This feature is located within the digestive tube and the nerve cord; it provides skeletal support through the length of the body. The dorsal hollow nerve cord comes from the ectoderm that rolls into a hollow tube during the development

(No author, 2015) The Wallaby belongs in Phylum Chordata because it has a dorsal notochord, which commonly is known as back bone. All chordates have a notochord at first, but some turn into vertebrae in the process of growing like wallaby. Chordates have a spinal cord which is a large nerve that helps the brain communicate with the small nerves. It is protected by the notochord. All

Grouping of organisms according to the similar anatomy helps to understand their evolution and how those organisms have being developed over millions of years. Similarly, structures of organisms have developed over years to function better to survive on the earth. Even though some organisms are unicellular, while some are multicelliular, both types of organisms have got particular structure to function that helps to fulfill their needs. Thus, structure and function of the organisms, including humans

Migration and parental care in Pisces Classification: Kingdom: Animalia Phylum: chordate Subphylum: vertebrata Class: Pisces Some of the well studied characteristics of Pisces are: 1. The body is covered with skin from the outer surface. Presence of scale in the body. 2. These are cold blooded animal which means that their body temperature changes according to the temperature of the surrounding. 3. The fertilization is external and reproduces numerous eggs having soft shell. 4. Respiration takes
