Summary:
- Use this resource to answer the questions that follow.
- In most fish species, fertilization takes place externally.
- Eggs are laid and embryos develop outside the mother’s body.
- Many adults of the same species may come together in a group and release gametes into the water at the same time, which is called spawning.
- A larva swims attached to a large yolk sac, which provides the larva with food.
- The larva eventually goes through metamorphosis and changes into the adult form.
- However, it still needs to mature before it can reproduce.
