Meet the infamous triggerfish! 🌊 These fish create nests in soft sand on the ocean floor, right out in the open. With an exposed nest creating a wide area for the fish to defend, some – such as the titan triggerfish – are known for their aggression towards intruders.

Triggerfish, known for their tough, armor-like skin and diamond-shaped scales, use their unique dorsal spines to defend themselves and wedge into crevices, making them difficult to dislodge or swallow. They are also known for their aggressive behavior, especially when guarding their nests. | Fishing World Tv

These little fish have trigger-like spines on the tops of their bodies that will pop when threatened, but they use it more like an anchor than anything else, locking them into small spaces to stop predators from getting to them.

16 reactions | Meet the queen triggerfish in Great Maya Reef! The name triggerfish comes from their ability to lock its dorsal fin. When upright, the dorsal-fin spine is locked in place by its second spine. The first spine can only be lowered after the second is pulled back, like a trigger! | Audubon Aquarium | Facebook
