The Surf-fishes
THIS is a large family, all the species of which are viviparous. The young are hatched within the body where they remain closely packed in a sac-like enlargement of the oviduct analogous to the uterus, until born. These foetal fishes bear at first little resemblance to the parent, being closely compressed and having the vertical fins exceedingly elevated. At birth they are 1 1/2 to 2 1/2 inches long, and similar to the adult in appearance, but more compressed and red in colour.
