Indus Worm

Variations: Odontotyrannus (allegedly)


Deep in the Indus River live worms that resemble those found in figs or rotten wood, only seven cubits (over 3 meters) in length on average, and thick enough that a ten-year-old boy could barely wrap his arms around one. They have two square teeth, one above and one below, each about 18 inches long. The skin is two fingers thick.

By day the worms remain underwater, wallowing in mud, but they emerge at night to prey on animals up to the size of a cow or camel. Victims are seized, dragged into the Indus, and devoured at leisure. The large teeth can crush their way through flesh, bone, and stone, and only the paunch is left uneaten. There have also been cases of hungry worms seizing drinking camels and oxen by the nose in broad daylight, and pulling them under.

Despite its predatory nature, it is prized by the Indians for its oil, which is highly flammable and capable of consuming wood and animals alike. Fires started by Indus worm oil can only be quenched by throwing large amounts of clay and rubbish on them. The oil is so rare that only the king of India may possess it. To obtain this oil, the worms are captured on hooks to which a lamb or kid has been chained, and slain with javelins, swords, and clubs. After landing and killing a worm, it is hung up for thirty days, with vessels underneath to catch the oil that drips from its carcass. 5 pints of oil are produced in this way. The worm is then disposed of, and the oil is sent to the king. Stored in clay vessels, it makes a formidable siege weapon.

The amphibious lifestyle, geographical location, and predatory habits of the Indus worm have led to comparisons with the Odontotyrannus, although the similarities end there.
