Whales of different species make very similar sounds.
You're right, the above statement is not true. Different species of whales make very different kinds of
sounds. Researchers have recently found that deep ocean whales, such as the
blue whale and fin whale, generate long, drawn out notes, that when recorded
and played at a faster speed, produce very rhythmic sounds. Whales living in
shallower waters, like the humpback whale, make sounds that are more melodic.
