Ecosystem Facts

🌊

Ocean Zones Most marine fish live in the photic zone (0–200 m) where sunlight penetrates. Below 1,000 m lies the mesopelagic and bathypelagic - home to bioluminescent species rarely seen alive.

🐠

Coral Reef Density Coral reefs cover less than 0.1% of the ocean floor yet support over 25% of all marine fish species - the highest biodiversity density of any marine ecosystem.

🦈

Open Ocean Migrants Pelagic fish like tuna and marlins travel tens of thousands of kilometres annually, tracking warm water currents and seasonal prey aggregations across entire ocean basins.

🌡️

Osmotic Challenge Marine fish lose water to the surrounding salty sea. They compensate by drinking constantly and excreting excess salt via specialised kidney cells and gill chloride cells.
