Here is a group of Esvirans in the clouds of Electris 7, feeding on the static electricity. Those energy orbs are baby Esvirans. They have a strong electromagnetic attraction to their parents' EM frequencies, so a baby never goes far from its nearest parent. A baby Esviran will quickly grow into the standard Esviran shape, depending on how much energy it has consumed.

An Esviran can levitate by manipulating its body's electromagnetism. Parents like to take their young into the clouds to feed them, as baby Esvirans can easily absorb the static electricity.
