Moriro ain Mangermachh (Sindhi: مورڙو ۽ مانگر مڇ) is a Sindhi folktale story about the valor and inventive technique by which the hero Moriro (the fisherman-seeker) killed a sea-monster Mangermachh (Alligator) by diving deep in an especially built iron cage.
[1][2] The brave fisherman went into the sea to bring back his six dead brothers, who had been swallowed one after one by the devouring mangermachh.
It is also written by the famous Sindhi sufi poet Hazrat Shah Abdul Latif Bhittai.
There lived in a fisherman named Aoubhayo (Sindhi: اوڀايو) with his wife Mai Kolachi.
Learning about the tragic death of his brothers, Moriro, though handicapped, resolved to take revenge and rid the villagers of the calamitous monster.
Villagers incised its stomach and brought out remains of all the dead brothers and buried them near the northeast side of Kalachi, at the foot of the mountain, and Moriro spent rest of his life as keeper of their graves.
