REVIEW OF MORPHOLOGICAL FEATURES

1 Platycephalidae

- Platycephalids are small to medium size, elongate

fishes with a strongly depressed head They are benthic ambush predators and are found primarily on sand or mud bottom of estuarine and coastal waters, bur some are associated with rocky or coral reef areas Some

species are commercially and recreationally important

- From the tropical Indo - Pacific region, 14 genera and approximately 50 species are recognized

- Demersal, burrying in the bottom Feed mainly on

crustaceans and small fishes Occurring at about

10-300 m Maximum length about 1.1 m

REVIEW OF MORPHOLOGICAL FEATURES

2 Menidae

- Menids are small to moderate fish with an extremely compressed disc-like body This monotypic famly occurs

in habitats ranging from estuaries to the outer shelf

REVIEW OF MORPHOLOGICAL FEATURES

3 Cynoglossidae

- Tonggue soles are elongate, small to moderate,

sinistral flatfishes with continuous medial fins They are benthic carnivores and occur on soft bottoms There are three Indo-Pacific general in two subfamilies with

approximately 60 species, many of which are

commercially important

- To about 48 cm maximum length, usually below 30

cm Tongue fishes are found in warm waters of all

oceans (between 40° latitudes) Most species occur in shallow water or estuaries; Symphurinae are in deep

water of 300-1,900 m; many species are commercially important Five species are known primarily from rivers
