Ninja Art: Tadpole Respiration

Used primarily after submerging themselves in water or being submerged in water, this technique allows the user to convert the oxygen within the water into a gaseous, breathable form, as they quickly develop internal gills. Upon doing so, the user can breathe underwater for as long as they continue the technique. However the technique does require a lot of chakra for constant activation, thus is cannot be sustained for long periods of time.

Sannoto has shown a little more versatility with this technique, as he was capable of converting the lower part of his body into a tail, allowing faster swimming. He also could absorb oxygen through his skin, rather than breathing it in.
