Temporal range: Late Cretaceous–Recent 
Zeiform bodies are usually thin and deep. Mouths are large, with distensible jaws, and there is no orbitosphenoid. Pelvic fins have 5-10 soft rays and possibly a spine, 5-10 dorsal fin spines and up to 4 anal fin spines. They range in size from the Dwarf Dory (Macrurocyttus acanthopodus), at 43 millimetres (1.7 in) in length, to the Cape Dory (Zeus capensis), which measures up to 90 centimetres (35 in).
