Yes, hydra do lay eggs.
Hydra, small freshwater polyps related to jellyfish and corals, reproduce in several ways, including budding (asexual reproduction) and sexual reproduction. When reproducing sexually, female hydras form eggs, while males produce sperm.
Based on the provided information:
- Eggs are formed by female hydras and initially remain attached to the female's body.
- Male hydras release sperm into the surrounding water.
- Fertilization occurs when sperm reaches the egg attached to the female.
- Once fertilized, the eggs develop a hard protective shell.
- These hardened, fertilized eggs are then released into the water.
This process allows the eggs to survive harsh conditions, such as freezing temperatures or dehydration, enabling them to overwinter before hatching when conditions become favorable. This method of sexual reproduction through egg-laying is crucial for hydra survival in temperate climates, allowing them to persist through unfavorable seasons.
Understanding the life cycle of hydra provides fascinating insights into the diversity of reproductive strategies in aquatic invertebrates.
