The Lost Clownfish

 

There are a number of problems which can arise as a result of Ocean Acidification - neurological problems in fish, are one of them.
 
Scientists have discovered that a lower pH can also affect neurological problems. A study showed that some young clownfish have lost the ability to navigate home because of changes to their sense of smell. This is because the fish can be attracted to smells they’d otherwise avoid, leading them to predators or leading them far away from their home. Scientists believe that the reason behind this is because of changes in a neurotransmitter in higher carbon dioxide levels. They also found that this might be reversible with the addition of a chemical. Although adding chemicals could be very costly, particularly as it would need extensive testing to make sure it wouldn’t harm other species.
