Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.; specca: Name based on the Anglo/Saxon 'specca' for speckled, referring to the heavy speckling of chromatophores over the body; noun in apposition.
