Daniel Sly, Sydney Beneath the Water (ANIMAL & NATURE 2025)

Sydney’s underwater world is full of fascinating creatures. Graceful weedy sea dragons float among the seaweed, while crested horn sharks rest quietly on sandy bottoms. The elusive blue-ringed octopus displays its bright warning colours, and schools of catfish move together in quiet harmony. These images showcase the unique and diverse life thriving beneath Sydney’s waves.
