The free screensaver, Trigger Happy, was created by RateMyScreensaver.com and contains 29 high resolution images of Triggerfish.

Triggerfishes are brightly coloured fish of the family Balistidae.

Marked by lines and spots, they inhabit warm coastal waters of the Atlantic, Mediterranean and the Indo-Pacific.

Triggerfish have a roundish, laterally flat body with an anterior dorsal fin.

They can erect the first two dorsal spines, the first one locks and the second one unlocks.

This prevents predators from swallowing them or pulling them out of their holes.

This locking and unlocking behaviour is why they are named 'triggerfish'.
