About the size of a modern trout (10 to 20 inches), it was a variety of the jawless fishes common during the Early Devonian Period. Its mouth was on the underside, suggesting that it was a bottom-feeder, moving its head from side to side to stir up prey such as worms and crustaceans, which it would vacuum into its jawless mouth. Its eyes were on top so that it could watch for predators such as the terrifying “sea scorpions” of its time, like Pterygotus.
