The eggs float freely with the currents until hatching. The larvae drift in oceanic waters or in the outer shelf for a period of 4–8 weeks until they metamorphose and develop barbels. Soon thereafter, most species take on a bottom-feeding lifestyle, although other species remain in the open water as juveniles or feed on plankton. [ 7 ]
The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if they must withstand physical force or desiccation. These type of eggs can also be very small and ...

The characteristic yellow patch, or saddle, located on the upper part of the fish’s caudal peduncle, gives the yellow-saddle goatfish their common name. [2] Different life stages of this fish may be found at varying depths, however, most yellow-saddle goatfish remain at around 20 metres (70 ft) of depth or in coastal regions with reefs. [ 3 ]
Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them. These eggs do not have a shell and would dry out in the air. Even air-breathing amphibians lay their eggs in water, or in protective foam as with the Coast foam-nest treefrog, Chiromantis xerampelina .
