* Sperm and eggs: Fish release their sperm and eggs into the water for fertilization.
* Development: Fish eggs develop and hatch in water.
* Larval stage: Fish larvae are typically free-swimming and require water to survive.
* Habitat: Most fish species are adapted to live in water, and breeding is an integral part of their aquatic life cycle.
While some fish species have evolved adaptations for breeding in specific environments, such as mud or damp areas, the majority rely on water for successful reproduction.
