Marine Biology Maldives | 2026 January: Marine Acoustics – The Sound from the Sea
The ocean is not a silent place. Underwater, a rich world of natural sounds reveals how marine life communicates, feeds, and survives. Scientists call this underwater world the marine acoustics.
Dolphins are among the most famous ocean musicians. They use whistles to socialize and clicks for echolocation, a biological sonar that helps them navigate and find prey. Each dolphin has a unique whistle, much like a name. These sounds can travel far through seawater, which carries sound more efficiently than air.
On coral reefs, you may hear a constant crackling noise. This often comes from parrotfish. As they bite algae from coral surfaces, their strong beaks scrape and crunch the coral skeleton. This process, called bioerosion, helps keep reefs healthy and even creates much of the white sand found on tropical beaches. Waves and moving water also play an important role in the ocean’s soundscape. As waves break on reefs and shorelines, they create low, rhythmic sounds that can be heard underwater.
These natural noises help some fish and coral larvae orient themselves and find suitable habitats. All of these natural marine sounds invite the body to relax and the mind to slow down. Enter the sea, let its timeless music surround you, and allow the ocean to quietly heal the soul.
