4.6 Perciformes
4.6.1 Apogonidae (Cardinal fishes)
In our collection there are 23 different species belonging to six different genera. The general body shape varies from slightly laterally compressed and elongated to strongly laterally compressed and deep bodied. The gut begins to coil during the early pre-flexion stage, and by the beginning of the flexion it becomes deeply coiled and extends to approximately the middle of the body. Also, the gut varies in size from long to very long.
The head shape is variable as some species have large, deep, laterally compressed heads with a short, round to truncate snout, while other species have a head of moderate size with an elongated snout. The large mouth reaches to about the middle of the eye or beyond and varies from nearly horizontal to very oblique. Small, villiform teeth are visible in both jaws
in some of the pre-flexion larvae. The round eye is large in size but may be small in some of the post-flexion larvae. The presence of head spination is variable among species; in some they are absent completely but in others they are present. But, in general, the head spination appears during pre-flexion stage and disappears or is greatly reduced prior to settlement. Also, scales are not formed until after settlement (Lies, 2000). The pigments vary from light, restricted to heavy, and distributed along the body, but they are consistently present on the dorsal surface of the gas bladder. There also, any pigmentation pattern can be found. (Figures 4.15- 4.37 & Plates 6-28)
