Logging (far left)—Whales sometimes rest at the surface of the water with part of their heads and dorsal fins sticking above the waves.

Breaching (second from left)—Some whales can leap completely out of the water and create an enormous splash. Dolphins are especially good acrobats.

Lobtailing (third from left)—Imagine a whale’s giant tail coming out and slapping the surface of the water. Wow, that’s one big wallop.

Spyhopping (right)—Some whales pop their heads out of the water to look around. Killer whales like to poke out their snouts to see what tasty treats might be close by.
