🎥 + 💭: @matthewunderH2O Sir, are those eggs in your mouth? 🐟 "Male cardinal fish take on the remarkable role of protecting their eggs through mouthbrooding. The dedicated dad holds the eggs in his mouth, carefully opening and closing it to oxygenate them until they hatch—a delicate and vital job. This clip was slowed down 4x so you can see it happening! Even more incredible is the mom’s clever strategy for their survival. She lays yolkless "dummy" eggs alongside the real ones, tricking the dad into thinking his brood is larger. This motivates him to guard the entire clutch with even more dedication." #MarineMonday #underwater #scuba
