Amphibians are a class of animals like reptiles, mammals, and birds. They live the first part of their lives in the water and the last part on the land. When they hatch from their eggs, amphibians have gills so they can breathe in the water. They also have fins to help them swim, just like fish. Later, their bodies change, growing legs and lungs enabling them to live on the land. The word "amphibian" means two-lives, one in the water and one on land.

Cnidaria is a phylum containing over 9,000 species found only in aquatic and mostly marine environments. All cnidarians have radial symmetrical. There are two major body forms among the Cnidaria - the polyp and the medusa. Sea anemones and corals have the polyp form, while jellyfish are typical medusae.
In this presentation, Phylum Phoronida, horseshoe worm is described. After watching this you will learn the characteristics and Examples Phoronis architecha, Phoronopsis, epistome, a lophophore-bearing mesosome, and an elongate trunk, metasome ectoprocts and cycliophorans. The brief description of Phylum Phoronida along with reproduction and fertilization also described. Its relationship with brachiopods as sister groups within Lophotrochozoa. It is part of the BS Zoology Course Animal diversity.
Define comparative anatomy.
Classifiy the phylum chordata.
Discuss the limb development of tetrapods.
Describe the features of tetrapods.
Explain the structure and function of the limb of tetrapods.
Discuss homology and analogy in relation to the limb of tetrapods.

This is presentation for school assignment on creating a power point, using slide share, and crating a lesson tied to the California Department of Education Standards
This is a presentation given at the 2009 Phycological Society of Southern Africa conference. The presentation looks at creating a debit credit account for an existing IMTA system in South Africa.
Designed for kids to learn about frogs and their life cycles, as well as their habitats, characteristics, diet, etc.
Special mention of a few native New Zealand Frogs is made.
Esta presentación ha sido elaborada para alumnos de 5º de Educación Primaria, en el área de Ciencias de la Naturaleza (Science). Con ella, podrán conocer los diferentes tipos de vertebrados que existen y poder estudiarlos de una forma motivadora y sintetizada.
CLASSIFICATION OF LIVING THINGS
KINGDOM ANIMALIA
The kingdom Animalia is large and compose of a wide variety animals, which vary greatly in structure,morphology and their body function.
THE DISTINGUISHING CHARACTERS
Animals are multicellular and each cell is bound by a plasma membrane.
Animals bodies are differentiated into tissues
Animals are heterotrophic.
Animals are capable of locomotion.
Animals have a nervous system
4. What do amphibians have in common? They live on land and in water They breathe water when they are young and either grow gills OR breathe air when they are older They are cold-blooded Many lay their eggs in water Most live in fresh water About 88% of amphibians are frogs
11. Camouflage Is common in frogs Most with camoflage are nocturnal awake at night this helps them hide Some can change colors only two colors
12. Poison Many frogs have toxins so other animals will not eat them; they taste bad Some frogs are very poisonous They usually have bright colors Some frogs get their poison from the animals they eat (e.g., ants)
13. Eating Frogs have teeth used to grind food Frogs have a sticky tongue Use it to catch food Most eat flies and insects Some large frogs eat small mammals, fish, and smaller frogs Very few eat just plants
14. Life Cycle 2. Tadpole (or Polliwog) 1. Egg – most female frogs lay eggs in early spring 4. Adult 3. Metamorphosis Captive frogs and toads can live up to 40 years
15. Frog Calls and Croaks Some are so loud they can be heard a mile away Many have deep calls or croaks They call by passing air through their throat The main reason they call is so males can attract females Other reasons are to guard territory, to forecast rain, and when under stress (if a predator is near)
16. Famous Frogs Frogs are used a lot in books, movies, commercials and cartoons!
