Some groups of insects ( e.g., dragonflies, mayflies, and mosquitoes) also lay eggs in water, and the larvae are aquatic. In animals that contain coelomic fluid instead of blood, oxygen diffuses across the gill surfaces into the coelomic fluid. Reptiles & Amphibians Science Lesson + Projects Easel Activity.
