Tuna

About

How tuna lives

Tuna are fast ocean swimmers with streamlined bodies built for long-distance hunting in open water. Some tuna can keep parts of their bodies warmer than surrounding seawater. Ocean animals navigate three-dimensional space, pressure, and constantly shifting currents.

Conservation

Status and habitat pressure

Vulnerable species face mounting risks and can decline quickly if habitats continue to shrink. Protecting tuna also depends on keeping ocean habitats healthy and connected.

Vulnerable species can decline quickly when habitat loss, climate pressure, or human conflict intensifies.
