Certain ponds and streams are used by frogs for breeding year after year. They travel overland from a wide area to these particular places during the breeding season, and meet up to find mates and lay their eggs. Let’s find out what are these frogs looking for?
Sometimes these favorite spots are filled in and build over during the construction of housing developments.
This is the reason construction of housing developments. This is the reason hordes of frogs are occasionally seen entering new states in the spring.
The circle shows the life cycle of the frog from spawn to newly hatched tadpole, to the final stage of tadpole development, to adult. The cycle usually takes about three months.
How do Frogs Develop?
During the spring, probably in May, you may hear a noise rather like the quacking of ducks. If you investigate this strange sound, the chances are that you will discover a frog pond in which the males are croaking for all their worth to attract the females. A male clambers onto the back of a female and as she lays eggs in batches, he fertilizes them.
A female can lay several thousand eggs in a season. A ball of protective jelly swells up around each egg as it is laid, sticking them all together into the familiar frogs’ spawn.
If you can find some frogs spawn it is worth keeping a dozen eggs in an aquarium at home to watch their development. The eggs hatch in about ten days and the larvae hang from the leaves of water plants until their mouths open.
They are active then and feed by scraping microscopic plants from the surfaces of plants and stones. Look carefully and you can see little tufts on either side of the head. These are the gills with which the tadpoles first breathe.
As the tadpoles develop, these gills shrivel up and a flap of skin grows over them, after about two months the legs appear, first the hand legs where the body joins the tail, and then the front legs.
The tadpole gulps air from the surface into its newly formed lungs and starts to include meat in its diet. It is important to feed you tadpoles on small pieces of cooked meat dangled in the aquarium on cotton threads at this stage.
The tail gradually shortens; the tadpoles stop feeding and eventually emerge as miniature frogs ready to feed on for your tadpoles to clamber on to. Once their lungs are fully formed they will soon drown if they cannot leave the water.
