Common clownfish

Clownfish form symbiotic relationships with sea-anemones found on coral reefs. The decline in coral reefs due to climate change is seriously impacting clownfish habitats.

Increasing ocean acidity may reduce the ability of clownfish to detect chemical signals in the water that help them find anemone hosts.

Rising sea temperatures may affect clownfish breeding and development, as they are known to only reproduce within a very small temperature range.
