Egg Guardians Open Response

Clownfish reproduction includes one of the most interesting examples of parental care in reef fish. This passage explains how the dominant female lays eggs on a flat surface near the sea anemone and how the male takes over much of the responsibility for protecting them. Readers learn how he fans the eggs with his fins to keep water moving over them, removes damaged eggs, and guards the nest from predators until the young hatch. The passage also introduces the unusual fact that clownfish can change sex, with the largest male becoming female if the dominant female dies.

This worksheet gives students strong practice with sequencing and process-based reading. They follow reproduction from egg laying to hatching while learning how parental care increases the chances that young clownfish will survive. Vocabulary related to spawning, fertilization, eggs, larvae, and parental care develops naturally through the passage. The sex-changing behavior also gives students an opportunity to think more deeply about adaptation and social structure, making this a rich reading for both comprehension and science discussion.
