The animal on the cover of Developing Backbone.js Applications is an Australasian snapper (Pagrus auratus), which is primarily found off the coast of Indonesia, China, the Philippines, Taiwan, New Zealand, Australia, and Japan. This fish goes by many names, depending on the region in which it’s found, but it is a prized eating fish everywhere.
Australasian snapper spawn inshore and live in rocky areas and reefs. During spawning, they turn a metallic green, an indicator of highly concentrated acid building up in their scales. Their growth patterns vary based on region, but they can live up to 40 years.
