Bubbles are useful

Bubble Homes and Fish Farts
by Fiona Bayrock

Kids love bubbles! They also, to a slightly lesser extent, like farts. But herring farts, also known as Fast Repetitive Ticks, come from air that they gulp at the surface, not from food. The bubble streams are their way of talking to each other. This is just one of the many fascinating ways that animals use bubbles. Besides communication, bubbles are used for travel (violet sea snails), warmth (otters), protection (spittlebugs), and more. Even humans have found a use for bubbles: as curtains to protect fish from lethal sound waves produced during underwater construction. 

A fun-filled book for animal-lovers.
