After about 10 days, the eggs hatch into larvae. The larvae are tiny, transparent fish that feed on plankton. They drift with the currents for several months, growing and developing.
As the larvae mature, they undergo a metamorphosis and begin to resemble adult swordfish. They develop a long, pointed bill and a long, dorsal fin. Their bodies become covered in scales, and they begin to develop the blue-black coloration that is characteristic of adult swordfish.
Young swordfish continue to grow and develop as they move through the ocean. They feed on a variety of fish, squid, and other prey. They may form schools with other swordfish, or they may live alone.
Swordfish reach sexual maturity at about 5 years of age. They can live for up to 15 years.
Here is a more detailed look at the life cycle of a swordfish:
1. The adult swordfish spawn in the tropical and subtropical waters of the Pacific, Atlantic, and Indian Oceans.
2. The females lay pelagic eggs, meaning that they float freely in the water column.
3. The eggs are fertilized by sperm from the male swordfish.
4. The eggs hatch into larvae after about ten days.
5. The larvae drift with the ocean currents and feed on plankton.
6. As the larvae grow, they gradually transform into juvenile swordfish.
7. The juvenile swordfish begin to develop their characteristic long sword-like bill and begin to actively hunt for prey.
8. The swordfish mature and reach sexual maturity after about 5-7 years.
Overall, the life cycle of a swordfish is complex and involves several stages as they grow and develop from a small egg to a large powerful fish.
