Eleutheronema tetradactylum, a species which has a range from India through SE Asia, may reach a length of over 1.5 m (60"), but is usually much smaller. It is silvery-green above and creamy below. It is a fish of commercial importance in India, and is highly esteemed in Thailand—to be fried, boiled, steamed, roasted, pickled, or dried. The specific name means ‘three-fingered’, referring to the three long rays. Some related species have six or seven, but the one which costs most in Thailand, where it is in demand for some special fish soups, is E. tridactylum, which has three.
