By overturning the nest-cave roof, the single-layered nest of eggs (outlined) is visible. A sheephead and rockfish, upper left, are showing considerable interest in the exposed nest. (Photo by Charles H. Turner.) ends, are attached directly to the rock but do not have adhesive threads. Immature eggs gave the nest a faded-pink appearance while mature nests were greyish due to pigment on the developing embryos. The earliest stages we observed were of recently differentiated em- bryos at a time when the yolk filled only a small portion of the egg sac. Excess space is rapidly used as the embryo develops, resulting in the tail curling back on the body in advanced stages. A well-formed em- byro, prior to hatching, nearly fills its egg case. Mature eggs average mm long by mm wide. The embyro within each mature egg is mm long and its head is directed op- posite (downward) the pole of attachment. The larva is released when its enveloping egg sac splits in a median plane. The attached end remains on the substrate, later disolving, and the larva drops out and swims away. Newly-hatched larvae are mm long, have prominent, large eyes and almost transparent bodies (Figure 4). A line of pigment extends posteriorly over the yolk sac then curves downward to the base of the ventral finfold, ending in the caudal region. There is another short line of pigment near the caudal peduncle at the dorsal finfold base. The.
