When Mrs. Seahorse lays her eggs, she does it on Mr. Seahorse's belly! She knows he will take good care of them. While he swims about, waiting for the eggs to hatch, he meets some other underwater fathers caring for their babies: Mr. Tilapia, who carries his babies in his mouth; Mr. Kurtus, who keeps his on his head; and Mr. Catfish, who is baby-sitting his young hatchlings. Beautiful collage illustrations introduce the very young to the wonders of aquatic life . . . and some very special daddies. A "hide and seek" feature with acetate overlays adds a colorful surprise.
