Frogs are amphibians in the order Anura. The order Anura is broken down into 22 different families of frogs and toads. Although they belong to the same order, frogs and toads are different in a lot of ways. Some of the more distinct differences are their skin and where they live. Frogs usually have smooth moist skin and toads usually have dry watery looking skin. Frogs spend most of their lives in or near water and toads spend more time on land. Amphibian means “double life.” Frogs and toads each have two parts to their lives: when they live on water and when they live land. A frog’s life starts in the water when it is hatched from an egg as a tadpole. A tadpole looks very different from an adult frog. A tadpole has a tail, no limbs, and breathes through gills. After a while the tadpole goes through metamorphosis. During the change the frog grows limbs, the tail disappears, it uses lungs to breathe, and it doesn’t have to live in water anymore. As a tadpole, the frog feeds mostly on vegetation. The tadpoles have a small rasping mouth suited especially for scraping algea from the bottom of ponds. Depending on the species, it can take a few weeks to a year or more for the tadpoles to become fully grown. Not all frogs hatch as tadpoles. Some species of frogs hatch as froglets. Froglets look just like adult frogs but are a lot smaller. Froglets don’t go through a metamophosis. Most species that hatch as froglets are found in dry places. Frogs who live in dry places where rains are seasonal have to grow up quickly because a tadpole will die if their temporary pond dries up. Adult frogs can live in water or on land, but it always needs to be near water so its respiratory organs don’t dry out. Frogs also need to be near water because most species of frogs in the water. In most species only male frogs croake. They croak to attract female frogs, to display distress, and to warn away other male frogs. A has to protect itself from the climate because they are cold-blooded. As you can see, frogs are very different animals. You will never find one like it.Order now
Study On Rana Pipiens Essay 483 Words | 2 Pages
Leopard Frog - Rana PipiensDistribution: Found throughout Ontario but more abundant in southern and central Americas. Range: Adults maintain small home ranges (up to 500 m2) in fields or open forest during the summer. Where terrestrial habitats are quite dry, home ranges include some shoreline. A minimum of 4 ha of terrestrial habitat is recommended for the vicinity of breeding sites, however, individual adults may move several kilometres away. Most recently metamorphosed froglets stay within 20 m of shoreline although some froglets begin dispersal before metamorphosis is entirely complete.Diet: Larvae eat algae, phytoplankton, periphyton and detritus. Adults eat mainly invertebrates...

Bonnie GleasonEcology October 20,1995Endangered SpeciesOne example that can affect mankind if not foretell it, that seems small and insignificant, is the disappearance of frogs. In 1970, a science students was studying frogs. While collecting information out in a field, she had to take care not to step on any of the frogs that she was studying as there was so many of them. Two years later, all she encountered were a few dying frogs with puffy red legs. The frogs' immune systems had been destroyed and they fell sick easily. In 1979, not a frog was to be found in...

THE DIGESTIVE SYSTEM OF THE FROG The digestive organs are usually divided into two main groups. The gastrointestinal tract or the alimentary tract and The accesory organs. The gastrointestinal tract (alimentary tract) -is a continuous tube running from the mouth to anus. This compose of mouth, parynx, esophagus, stomach, small intestine and large intestine.

The Australian Cane Toad Essay 2726 Words | 10 Pages
THE AUSTRALIAN CANE TOADIntroductionThe cane toad, Bufo marinus, or giant toad, was introduced to Australia by the sugar cane industry with government sanction, in order to control two specific pests of sugar cane. The grey backed cane beetle and the frenchie beetle. Native to Central and South America, the cane toad has been introduced to several Pacific islands as well. One hundred and one toads arrived at Edmonton in North Queensland in June 1935. About 11 sugar growing locations in northern and central coastal Queensland received authorized shipments. People at Normanton and Burketown, and in northern New South Wales deliberately...
Cloning Endangered Species Essay 724 Words | 3 Pages
Cloning is the production of duplicate copies of genetic materials, cells, or entire multi-cellular living materials. For years cloning had only been a fantasy, but with new scientific research cloning can be very successful. Because there are so many advantages in areas like agriculture, medicine, and biological research in producing genetically identical organisms, artificial cloning has become the focus of attention with scientists today. "At last there is hope of saving endangered species. We might be able to witness the cloning of now nearly extinct condors, tigers, rhinoceroses, and so many other living marvels. " That was a quote from...
Effects of Acid Rain on Water Essay 368 Words | 2 Pages
The effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes. Acid rain flows to streams, lakes, and marshes after falling on forests, fields, buildings, and roads. Acid rain also falls directly on aquatic habitats. Most lakes and streams have a pH between 6 and 8. However, some lakes are naturally acidic even without the effects of acid rain. Lakes and streams become acidic (pH value goes down) when the water itself and its surrounding soil cannot buffer the acid rain enough to neutralize it. In areas like the Northeastern...
Genetics Essay 721 Words | 3 Pages
The process of cloning is the process of using the genes of a being to create another being genetically identical to it. Cloning technology has been called the "forbidden fruit of biology" (Begley 54). For years, scientists have been trying to perfect the cloning technique. In Scotland, scientists at the Roslin Institute have finally succeeded. Their success comes in the form of a Finn Dorset ewe named Dolly. Dolly is a clone. Now that the cloning of mammals from body cells has been accomplished, we are forced to consider what stand must be taken on the issue of cloning human...
Heaney Poems Essay 1086 Words | 4 Pages
“On the surface, Heaney’s poems are very simple. This simplicity however is deceptive, for the poems are usually most subtle and complex. ” What do you think of this response to Heaney’s poems? Heaney’s poetry may at first, initially seem simple, yet his poems do contain more complex underlying themes and ideas. Heaney has refined his poetry to such a simple state, such as in ‘Punishment’, Blackberry Picking’ and Death of a Naturalist’, that his poems are superficially simple, yet have complex, thought provoking ideas seeded deeper below. This initial simplicity is seen in the poem ‘Punishment’, yet is deceptive,...
Cloning Of Animals Essay 488 Words | 2 Pages
Cloning of AnimalsOn Sunday, February 23, 1997, Scottish researchers broke one of nature'sgreatest laws by cloning a lamb from a single cell of an adult ewe. Thisbreakthrough opens the door to the possibility for the cloning of other mammalsincluding humans. This remarkable achievement is being looked at as a great advancement inanimal agriculture. But this achievement could lead to ethical questions ofstandard. Researchers lead by Ian Wilmut of the Roslin Institute in Midlothian,Scotland, showed that a fully differentiated cell from the mammary tissue of anewe could be manipulated in such a way as to produce a genetically identicalcopy of the...
