What Makes them Special?

Built for Speed

Mackerels are perfectly designed for fast swimming. Their long, streamlined bodies, narrow tail base and powerful forked tails create very little resistance as they race through the water.

Tiny Fins with a Big Purpose

Look closely near the tail and you will see a row of small fins called finlets. These help control water flow around the body and reduce drag at high speeds, a clever adaptation shared with their tuna relatives.

High-Speed Hunters

Cero, King Mackerel and Wahoo are active predators that chase schools of smaller fish. Rather than hiding and waiting for prey, they rely on speed, sharp eyesight and razor-sharp teeth to catch it.

 More Than Just Silver

Their colours also help them hunt. A dark blue or green back blends with deeper water when seen from above, while their silvery sides and belly blend with the bright surface when seen from below.
