Scientific Details

Meristics.
Dorsal fin spines/rays: X, 21-24
Anal fin spines/rays: IV-V, 20-25
Caudal fin rays: 13
Pectoral fin rays: 12-15
Ventral fin spines/rays: I, 6-7

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Detailed descriptions of fin count and other meristics are in:

Order level detail.
The order Zeiformes is a small order of marine fishes found in all oceans, and most are deep-bodied, highly compressed fishes, with large heads, large highly protrusible mouths and large eyes located near the dorsal profile. Many have elongate dorsal-fin spines, often with filamentous tips, and some have a row of enlarged scales or spiny scutes at the dorsal and anal-fn bases, or along the belly. Dories and their allies live near the bottom on the continental slope often around seamounts, to depths of more than 1000 m. Two species enter bays and harbours. Many species are commercially important.

Family level detail.
Members of the family Zeidae are very compressed deep-bodied fishes with large heads with large protrusible mouths. Body scales are either small or absent except for lateral line scales. Dories have large bony bucklers at the bases of the dorsal and anal fins an dalong the ventral surface. Species are commmercially important.
