Thrissops was a fast predatory fish about 60 centimetres (24 in) long, that fed on other bony fish.[4] It had a streamlined body with a deeply cleft tail and only very small pelvic fins. Thrissops was one of the smaller members of the order Ichthyodectiformes, which also included giants like Xiphactinus and Saurodon.[5]
