词汇 | sea horse |
词源 | sea horse. The little sea horse, or Hippocampus, as it is known scientifically, swims upright and has a head and an arched, very horselike neck. Sea horses are also unusual in their breeding habits. During mating, the female’s eggs are fertilized by the male as they are shed, but the female deposits them in the male’s abdomen. The male’s pelvic fins are converted into a large incubating pouch that holds the eggs and he carries them about until they are ready to hatch, appearing as if he were pregnant. |
