Amber Holmes-Turner Biology 2 12. Rays: a broad, flat marine or freshwater fish with a cartilaginous skeleton, winglike pectoral fins, and a long slender tail. 13. Tilapia: an African freshwater cichlid fish that has been widely introduced to many areas for food. 14. Tetrapod: a four-footed animal, especially a member of a group which includes all vertebrates higher than fishes. 15. Gnathostomes species: The Gnathostomata are a superorder of sea urchins, including the familiar sand dollars. Gnathostomatans are irregular in shape, but unlike other irregular sea urchins, possess a feeding lantern. The mouth is located in the centre of the lower surface, as it is in most other sea urchins, but the anus is found to one side of the upper surface, rather than being central. The members of the group are adapted for burrowing in soft-bottomed marine environments. 16. Order Urodela: One of the orders of the class Amphibia, also known as the Caudata. The members of this order are the tailed amphibians, or salamanders, and are distinguished superficially from the frogs and toads (order Anura) by the possession of a tail, and from the caecilians (order Apoda) by the possession of limbs. 17. Order Anura: an order of animals in the class Amphibia that includes frogs and toads. There are more than 5,000 species currently described in the order. The living Anurans are typically divided into three suborders: Archaeobatrachia, Mesobatrachia and Neobatrachia 18. Order Apoda: The smallest order (sometimes called Gymnophiona) of the class Amphibia, known as the caecilians. These are wormlike, legless animals with indistinct or even hidden eyes. A series of annular grooves is usually present along the length of the body, heightening the resemblance to an earthworm 19. Amphibians: cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, and salamanders. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage. 20. American alligator: a large semiaquatic reptile similar to a crocodile but with a broader and shorter head, native to the Americas and China 21. Marsupials: a mammal of an order whose members are born incompletely developed and are typically carried and suckled in a pouch on the mother's belly. Marsupials are found mainly in Australia and New Guinea, although three families, including the opossums, live in America. 22. Orangutans: a large mainly solitary arboreal ape with long reddish hair, long arms, and hooked hands and feet, native to Borneo and Sumatra. The mature male develops fleshy cheek pads and a throat pouch.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
