Starfish and Their Babies — Passage

Starfish, or sea stars, exhibit diverse and fascinating reproductive strategies that ensure the continuation of their species in the vast oceans. Many starfish species reproduce sexually, releasing eggs and sperm into the water where fertilization occurs externally. The resulting larvae, known as bipinnaria or brachiolaria, drift in the plankton, undergoing a complex metamorphosis before settling on the ocean floor as juvenile starfish. Some species practice brooding, where females protect their developing eggs beneath their arms or in special pouches. Remarkably, certain starfish can also reproduce asexually through fission, where the animal splits its body to form two or more new individuals. This variety in reproductive methods showcases the adaptability of starfish to different marine environments and contributes to their widespread distribution across the world's oceans, making them an intriguing subject for studying marine life cycles and population dynamics.
