Dive to the deep.
Dive to the deep.
When a large whale takes a deep dive, it often arches its body and move some of its mass above water to dive in a steeper angle. As you watch the whale proceed forward, the last thing visible before the whale is completely submerged is usually the underside of the tail flukes. This is called fluking. Although this is a common behaviour upon a deep dive, fluking does not always occur. Original public domain image from Flickr
