Description

Ichthyodectes ctenodon ("fish biter with comb teeth") was an ichthyodectid over 3 m (9.8 ft) in length.^[1] It lived in the Western Interior Seaway of North America during the late Cretaceous. It was closely related to the 4–6 m (13–20 ft) long Xiphactinus audax, and the 2 m (6 ft 7 in) long Gillicus arcuatus, and like other ichthyodectids, I. ctenodon is presumed to have been a swift predator of smaller fish. As its species name suggests, I. ctenodon had small, uniformly sized teeth, as did its smaller relative, G. arcuatus, and may have simply sucked suitably sized prey into its mouth.^{[citation needed]}
