Smoke and Mirrors on Coral Reefs: How a Tiny Fish Deceives its Prey - @UniBasel - 0 views

  •  
    Basel Zoologists are unveiling the colorful secrets of coral reefs: On the Australian Great Barrier Reef they discovered a coral reef fish, the dusky dottyback that flexibly adapts its coloration to mimic other fishes and in doing is able to prey on their juvenile offspring. By changing colors, the dusky dottyback also decreases its risk of being detected by predators. The study has been published in the latest issue of the renowned scientific journal Current Biology.
