TED-Ed: The big-beaked, rock-munching fish that protect coral reefs | Mike Gil

Parrotfish play a crucial role in maintaining coral reef ecosystems by consuming seaweed that competes with coral larvae for space. Their unique beak-like teeth allow them to scrape seaweed from rocks, promoting coral growth. However, human activities like overfishing and pollution have disrupted these ecosystems, leading to unchecked seaweed growth and weakened coral defenses. Understanding parrotfish behavior and their ecological importance can help develop strategies to preserve coral reefs, which are vital for marine biodiversity and human benefits.
