One would assume that a shy fish is always shy, but research has found this isn’t always the case. Scientists working with two species of damselfish on Australia’s Great Barrier Reef have discovered that when water temperatures increase by as little as three degrees, fish personalities 1 change. They became an average of six times more active, four times more aggressive and four times bolder. Shy fish in cooler water that cowered 2 in shelters for up to ten minutes after being threatened by a stick would immediately emerge from the shelter in warmer water. So what does this mean in a time when oceans are becoming warmer? Are we going to hear news stories about mysterious fish attacks sinking ships? Scientists don’t think so. While many fish become bolder in warmer water, not all fish do. Scientists believe fish populations will adapt, and it will still be safe to sail the seas, even during the dog days of summer.
