Echolocation is when mammals produce sound waves and listen to the echoes that return from objects around them. Whales generally breed once every 2 to 3 years throughout their average lifespan of 80 to 90 years. WebLike other mammals, whales breathe air, are warm-blooded, and produce milk to feed their young.

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. Therefore, attempting to injure and kill a large whale would likely be a huge waste of time and energy. Sometimes theyll also slap their tails against the water. Sperm Whales.
