While visual observations are still a very important part of investigative studies, various research efforts today can include hydrophones permanently mounted on the ocean floor; hydrophones trailed behind boats under the water; photography and video of individuals; attachment of cameras and acoustical devices to the whales; skin biopsies for DNA analysis; laboratory analysis of fecal samples to determine food preferences; transmitters to send signals to and from satellites and data collection systems; radio tagging to record pitch, roll, and acceleration during dives; dive recorders to determine how feeding at depths occurs; etc.. A prominent blue whale researcher has said: The mysteries of the blue whale will be solved, not by my generation or the next, but in the next30 years from now. This suggests that acoustic crypsis is being used by whale mother-calf pairs to minimize the risk of eavesdropping and detection by predators while still allowing for communication between mother and calf over relatively short ranges.
