Description
This fish was usually less than 15 centimeters long, and its appearance must have been very similar to that of the modern Elops . Like the latter, Davichthys had an elongated body with an oval cross-section, slightly flattened laterally. The eyes were rather large, while the mouth had robust jaws. The dorsal fin and the anal fin were rather small; the ventral fins were inserted far back, under the dorsal. The pectoral fins were placed low on the body. The caudal fin was very broad and strongly forked.[2]
