Humpback Whale Spout

undefined

All whales have to surface to breathe and when they exhale they produce a spout of moist, warm air from blowholes on the top of their heads, like this Humpback Whale near Shelter Island north of Juneau. Different whale species can be distinguished by the size and shape of their spout. For instance, Right Whales have two blowholes, creating a v-shaped spout.
