Ocean Sunfish

Mola mola

Also known as Common Mola

The Ocean Sunfish has a huge laterally flattened body, tall dorsal and anal fins, and a short rounded rear edge instead of a typical tail. It sometimes rests near the surface or visits cleaning stations where smaller animals remove parasites.

Why interaction risk is high
Its great mass and fins can injure close swimmers; never touch, chase, or obstruct it.
Why it is dangerous
A startled animal weighing hundreds of kilograms can collide with swimmers, divers, or small craft.
How to recognize a risky encounter
Confirm the truncated disk-shaped body with very tall dorsal and anal fins moving together.
What to do
Never touch, tow, ride, or crowd the fish; move away calmly and keep vessels slow.
Responsible observation
  • Surface: Watch for a tall fin moving slowly or a body lying flat.
  • Boating: Reduce speed and give any surface-resting animal a wide berth.
