It is beginning the process known as 'metamorphosis' - the tail is absorbed, and the legs start to grow. At the same time, the tadpoles gills are changed into lungs - in preparation for a semi-aquatic life.
frog eggs ==> tadpole ==> back legs appear ==> young adult frog (tail disappears) ==> adult frog

Back legs
Back legs
Tadpoles first grow hind legs and then front legs. the hind leg appear right where the tail starts
Mud is ephemeral - it may appear for a short time following a significant rain but quickly disappears. The water is either absorbed by the soil or evaporates.Mud is ephemeral - it may appear for a short time following a significant rain but quickly disappears.

To cease to appear or to be perceived; to pass from view, gradually or suddenly; to vanish; to be no longer seen; as, darkness disappears at the approach of light; a ship disappears as she sails from port., To cease to be or exist; as, the epidemic has disappeared.
Yes, because a male makes the babys when they mate
It typically takes about 6-9 weeks for a tadpole to develop hind legs. The front legs usually appear a week or two later. These stages of metamorphosis vary depending on the species of frog and environmental conditions.
No they are still vertebrates. And just to intrigue you further, though tadpoles might not appear to have a vertebrae, they too have one.
Red is the color that disappears first underwater as water absorbs and scatters light. As depth increases, longer wavelengths such as red are absorbed more quickly, making them appear darker or even black.
Tadpoles can originate from eggs laid by frogs or toads that visited the pond in previous seasons. Frogs and toads can travel long distances to find suitable breeding sites, so tadpoles may appear in seemingly isolated ponds. In some cases, birds or other animals may inadvertently introduce frog eggs to a pond by carrying them on their feet or feathers.
