A farm pond, usually dry during winter, has plenty of water and aquatic pond life duringthe summer. One summer, Sarah returns to the family farm from college. Observing thepond, she is fascinated by some sixlegged organisms that can crawl about on submergedsurfaces or, when disturbed, seemingly "jet" through the water. Watching further, she isable to conclude that the "mystery organisms" are ambush predators, and their preyincludes everything from insects to small fish and tadpoles

Sarah observed that the mystery pond organisms never come up to the pond's surface. Ifshe catches one of these organisms and observes closely, perhaps dissecting the organism, she should find

gills

fins

feet

None of the above
