Connections on the Reef: Clownfish, Anemones, and Climate Change
View through CrossRef
From their adorable name to their leading role in the movie Finding Nemo, many people find clownfish, also called anemonefish, cute and lovable. Clownfish must live in animals called sea anemones to survive on a coral reef. For 19 years, we followed two-banded anemonefish off the coast of Israel in the Gulf of Eilat (Aqaba), Red Sea. Based on their size, we divided the fish into adults, teens, and babies. In 1997, 195 fish of all ages lived at the site. By 2015, 52 fish—mostly adults—remained, a 74% drop. From 1997 to 2015, the number of sea anemones also fell from 199 to only 27, and each one was more crowded with anemonefish. Climate change may affect sea anemone survival. Without their sea anemone homes, clownfish cannot exist, raising concerns about their future.
