J is for Javan Rhino. The next letter in the endangered species Animal Alphabets. Considered one of the rarest large mammals in the world, the Javan Rhino gets its name from one of the islands from which its population was once large – Java in Indonesia. In the 1600’s the Dutch introduced coffee beans to Southeast Asia. One location that several coffee plantations were established was Java. Somehow the name stuck as another term for coffee no matter its origin.
