The Myth
The Saratan is a colossal sea creature described in Arabic literature as a monstrous crab of unimaginable size. Sailors believed it lived far out at sea, where it remained so still and vast that it was often mistaken for an island. Its back was said to be covered with soil, plants, and even trees, giving the illusion of solid land rising from the ocean.
According to accounts repeated by sailors, ships sometimes anchored beside what appeared to be an island, and crews went ashore to rest. They lit fires, gathered wood, and explored valleys and fissures, unaware that the land beneath them was alive. When the heat of the fire reached the Saratan’s shell, the creature stirred and began to move, sliding back into the sea with everything on its back. Only those who realized the danger in time and fled were said to survive.
The ninth-century scholar Al-Jahiz, writing in Kitāb al-Ḥayawān (The Book of Animals), reported these stories but noted that he had never met anyone who could truthfully claim to have seen the Saratan with their own eyes. He placed it among other legendary sea monsters such as the sea-dragon and the great whale, repeating sailors’ tales while acknowledging their fantastical nature.
The Saratan also appears in The Wonders of Creation by al-Qazwini, where it is listed among the marvels of the seas. In the tales of One Thousand and One Nights, the creature is echoed in the first voyage of Sinbad the Sailor, where sailors land on what they believe to be an island, only to discover it is a living monster that dives beneath the waves.
Across these stories, the Saratan is remembered as a deceptive giant of the sea—silent, immobile, and deadly—whose vast shell lured the unwary and whose awakening meant sudden destruction.
