Early in its development a tadpole breathes with gills.
Young amphibians, like the larval frog or tadpole pictured here, spend their early years in the water, breathing through gills in the side of their head in much the same way as fish do.
Frogs were not symbols of death but, on the contrary, of rebirth and renewal, because of its remarkable metamorphosis of egg into tadpole and from tadpole into frog.
One of the characteristics of amphibians is metamorphosis; when the larva or tadpole living in water and breathing with gills develops into an adult, it leaves the aquatic environment and breathes with lungs like a land animal.
Toad tadpoles appear to be distasteful to many predators, and, perhaps as a result of this, are much more often to be seen in open water than those of the common frog.
In several species, a parent remains with the non-feeding tadpoles at the nest.
The cells divide and change until they have a head and short tail, like tadpoles .
They will also prey on crayfish, frogs, tadpoles , and other aquatic dwellers.
We have observed that green frog tadpoles react less strongly to predators at very low resource levels.
Most tadpoles are suspension feeders, filtering out tiny particles while continuously pumping water.
