Description
Advanced embryos, larval and early juvenile snook, Centropomus
undecimalis, are described from laboratory reared specimens. This description
includes details of advanced embryos, changes in body shape,
pigmentation, and osteological development. Eggs ranged from 0.68 to
0.73 mm in diameter with a single oil globule. Larvae were between 1.4
and 1.5 mm standard length at hatching. The yolk sac was absorbed by
2.2 mm and adult pigmentation began to appear on the head and fins by 7.0
mm. Ossification had commenced by 5.5 mm and all bones, except the
ethmoid and preyomer, had at least begun to ossify by 21.9 mm. Illustrations
of snook eggs and larvae, including details of the caudal skeleton,
are presented to show changes that occurred during development.
