Mimi or Belangkas (Limulidae tribe) includes four types of animals (arthropods) that inhabit the shallow waters of swamps and mangrove areas. All of them are members of the tribe of Limulidae and become the only representatives of the Xiphosurida people who still survive on earth. These animal fossil prints have not changed in significance since Devon (400-250 million years ago) compared to their present form, although the species are not the same. 
The Acehnese call momo. This animal is monogamous, so it is often used as a symbol of sibling married couple. The English know him as a horseshoe crab or "horseshoe" because of its shape that is considered like a horseshoe.
Momo eggs can be eaten and rich in nutrients. contain high protein that can not be consumed excessively. I often eat it while fishing in the estuary near the beach.
