Once upon a time, they were 'mimi lan mintuno',
but not anymore.
'Mimi lan mintuno' is a saying in Javanese culture, which used to speak as 'be like a mimi lan mintuno', it's an idiom about loyalty or true love of a couple, which taken from an animal's habit. In biology, it's known as horseshoe crabs, which it's not a crab at all, which grouped as Chelicerata and classified in Xiphosura. Well, now I also knew the connection between 'mimi lan mintuno' and 'horseshoe crab', which is very interesting to me lately. - added August 4, 2012.
