Family AMIIDAE 



Body oblong or elongate, sometimes compressed and elevated. 

 Head rather large and compressed. Mouth cleft wide. Teeth villi- 

 form, in bands in jaws, on vomer and palatines, none on tongue; 

 canines sometimes present. Preopercle with double ridge, edges 

 entire or serrate. Opercular spine little developed. Pseudobranchiae 

 present, usually well developed. Branchiostegals 6 or 7. Pyloric 

 appendages few, when present. Lower pharyngeals separate, with 

 sharp teeth. Scales usually rather large, occasionally small, striated 

 and ctenoid, sometimes cycloid, sometimes deciduous. No axillary 

 ventral scales. Cheeks scaled. Lateral line usually complete and 

 distinct. Dorsals well separated, first with 6 or 7 rather strong spines. 

 Usually no dorsal sheath. Soft dorsal with spine and 7 to 10 rays. 

 Anal short or like soft dorsal, spines usually 2, rarely 3. Ventrals 

 thoracic, with spine and 5 rays. 



Small fishes of tropical seas, abundant on coral reefs or in sheltered 

 situations, some in deep water. Many are brilliant in color, often 

 bright red or pink. Some are interesting in the habit of the male 

 carrying the ova and very young in his mouth. Until the present 

 time only a few species were known to use this method, though now 

 we have found this condition more or less general. The male at this 

 season may easily be known by its swollen chin. The ova are carried 

 about packed closely as a dense mass.
