Large predator fish play a vital role in coral reefs. Research indicates that reefs with these fish have more essential nutrients like phosphorous and nitrogen. In comparison, reefs lacking large fish have about 50% fewer nutrients. These nutrients are crucial for maintaining the ecosystem health of coral reefs and supporting marine life. Moreover, longer fish … Read more

Juvenile fish need adequate dissolved oxygen (DO) levels for survival and acclimation. Low DO affects their tolerance levels. High-quality nursery habitats enhance their survival. Poor DO conditions may reduce tolerance and increase aggression, especially when water fluctuations occur. Predator protection is also vital during their juvenile phase. Higher levels of dissolved oxygen enhance habitat quality. … Read more

Jellyfish reproduce in two main ways. Polyps reproduce asexually by budding. The adult form, called medusa, reproduces sexually. Medusae release sperm and eggs into the water, creating larvae. This dual reproduction method helps ensure the survival and continuation of the jellyfish lifecycle. The planulae then settle on the seafloor and transform into polyps. Polyps reproduce … Read more
