Whale Spouts
All whales have to surface to breath and when they exhale they produce a "spout" of moist, warm air from blowholes on the top of their heads. The different whale species can be distinguished by the size and shape of their spout. Three baleen whale species are shown below.
Minke Whale
This is the smallest of the baleen whales, which is up to 29 ft (9 m) long. The spout is low and barely visible.

RIGHT WHALE (below) This species is named as the 'right' whale to hunt because it is slow and easy to catch and is rich in blubber and baleen. It can grow to over 49 feet (15 m), it has two blowholes and a v-shaped spout.
