The Impact of Ocean Acidification on Olfactory Navigation in Coral Reef Fish Larvae
Quick fact
Ocean acidification can disrupt the olfactory receptors of coral reef fish larvae, causing them to lose their ability to distinguish predator cues from settlement cues, and making them more attracted to chemical signals they should avoid.
Why this is interesting
Imagine you’re a tiny fish larva, lost in the open ocean, and you rely on your sense of smell to find your way home—but that smell is slowly vanishing. What would happen to you if the ocean became more acidic?
