The black mamba and the blue-ringed octopus are among Earth's most venomous animals. Beyond that, they have little in common. One is known for its great size; the other is adorably small. They'd never meet in real life because one lives on land and the other dwells in the ocean, but imagine if they did meet. What would the battle look like? Who might win? This engaging volume compares the animals' qualities to see who might emerge victorious. Striking images and amazing statistics enhance the narrative as it addresses important science concepts.
