Amphibians

In temperate areas where their are seasonal changes, frogs will lay their eggs in the spring.

Baby frogs and toads are called tadpoles. Baby newts are called efts. And baby salamanders are called nymphs.

Order Anura (frogs and toads)

Adult frogs and toads are characterized by long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail. Most have a semi-aquatic lifestyle, but move easily on land by jumping or climbing. They typically lay their eggs in puddles, ponds or lakes; and their larvae, called tadpoles, have gills and develop in water.

Order Caudata (newts and salamanders)

Cuadata have slender bodies, short legs, and long tails. The moist skin of the amphibians fits them to habitats either near water or under some protection on moist ground, usually in a forest. Some species are aquatic throughout life, some take to the water intermittently, and some are entirely terrestrial as adults. Salamanders superficially resemble lizards, but are easily distinguished by their lack of scales. They are capable of regenerating lost limbs.

External fertilization.

A typical amphibian lives on the land until it is time to breed and lay eggs, when it returns to the water.

Yes...just seen it happen. In the morning, adder had frog in it's mouth but released after a while when frog gave out it foamy deterrent. 5 hours later adder had frog almost totally in it's mouth...just back legs sticking out...frog struck out again and adder needed to take in air and so released frog!

Forest destruction has also caused amphibians to move miles from their natural habitat.

Hope this is helpful

If 20%of the

all amphibians are borm with a shell or in an egg or in water.

Many amphibians, like the frog, reproduce in water as the new generation will spend its first few months a water animal. For instance, the frog lays an egg, which becomes a tadpole, breathing through gills. Were the amphibian not to return to water, any eggs that were fertilized would not survive.

It's a type of fish.

Amphibians live double lives by changing colors. They also live double by changing from human to fish. This sounds odd, but by having lived human for so long, they provide their smarts when they are fish.

During the U.K.'s spring months of February and March, many fresh water ponds are occupied by one or more species of amphibian. Each male will try and claim a female. Those males who are successful will fertilize up to four thousand eggs as the female lays them into the shallower water, often within clumps of aquatic plants.

The fertilized eggs are just the first stage in a remarkable transformation called metamorphosis. This describes the process of change from egg to tadpole (the larval stage), through to adult amphibian.

Many of the eggs which are laid will hatch into tiny tadpoles with dark, oval bodies and a waving tail which propels them through the water. At this stage, they do not resemble the parents in any way and only a small proportion of the tadpoles will ever reach adulthood. Many will be eaten by other creatures or die of disease.

At first the tadpoles eat the remaining egg gel from which they hatched. They then eat submerged vegetable matter whilst absorbing oxygen directly from the water using their gills (fish also use gills to extract oxygen from the water). As they grow in size, lungs will develop inside the tadpoles and they will then begin to visit the surface in order to breathe in some of their oxygen from the air. Eventually the diet becomes more carnivorous as the tadpole will start eating small invertebrates in the water.

As their bodies continue to grow, legs will sprout out and in frogs and toads the tail will be reduced in size. From now on, the tadpoles will become more adult like as time passes. Eventually the gills will disappear and the body changes shape into that of a miniature adult. Frog and toad tadpoles will lose their tails all together. At this stage they normally leave the water. In Britain, most of these changes take place during a 4-5 month period so that by August each year, many British amphibians have completed their development from egg to tiny adult.

Some ponds become home to many thousands of toads and frogs in spring time when mating takes place. One such location is at the Woodland Education Centre, situated in East Devon, South West England. On only a few nights, visitors to the reserve are treated to a natural spectacle of vision and sound. Thousands of mating toads can be heard and seen within the Centre's ponds and lake.

"vent" describes the opening on the underside of the animal which contains the reproductive organs. it is also used as a common point in the measuring of amphibians by researchers. known as SVL (snout to vent length) it ensures that accurate data is collected by using standard points on all animals.

amphibians use gills AND lungs, fish/marine life use gills alone

There are many poisonous amphibians, in which case poison dart frogs are notorious.

Means amphibians don't have hair/fur,scales,or any type of skin.

No

No.

No, frogs only lay clear eggs with a brown or black nucleus. Normally in some sort of water. Frogs lay them in large clumps and toads lay them in a string.

In water like auther frogs

Yes, they do. All amphibians are vertebrates, so they have backbones.

The relationship of amphibians and insects is a predator-prey relationship. Amphibians hunt insects for food. As such, they help to control insect populations.
