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; ancora: Name from the Latin 'ancora' meaning hooked; referring to the distinctive orange hook-shaped marking on the side of the head; an adjective.
