Sheartooth

A Sheartooth is a kind of fish living in Umbriel's sump. Sheartooths have a maw full of teeth. The teeth are even bigger than those of a shark. They can be as long as fifteen feet long. Its tail is long, whiplike, and it has two great swimming fins set under it, like a whale. They have an incredible force.

A Sheartooth attacked Mere-Glim during his first day at the sump, and it severely wounded Wert. Skraws ate sheartooth steak sometimes.
