This image provided by NOAA shows a deep-sea Chimaera. Chimaeras are most closely related to sharks, although their evolutionary lineage branched off from sharks nearly 400 million years ago, and they have remained an isolated group ever since. According to scientists the lateral lines running across this chimaera are mechano-receptors that detect pressure waves, like ears. Scientists using cutting-edge technology to explore waters off Indonesia were wowed by colorful and diverse images of marine life on the ocean floor. They predicted Thursday that as many as 40 new plant and animal species may have been discovered during the three-week expedition that ended Aug. 14. NOAA Okeanos Explorer Program/AP
