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.; karaspila: Name from the Greek words ' kara' meaning head and 'spilous' for spot; referring to the distinctive occipital spot; an adjective.
